The short answer
For most RVers the best exterior cleaning setup is a waterless wash-and-wax like Aero Cosmetics Wash Wax ALL (safe on fiberglass, gelcoat and decals, and allowed at campgrounds that ban hose washing), a concentrated bug and tar remover such as Bugs N’ All for the front cap, Star brite Black Streak Remover for the streaks under windows and rails, a soft flow-through brush on a 5–12 ft pole, and plenty of microfiber towels. Clean a rubber roof with Dicor roof cleaner a few times a year, and polish with 3D Speed (or compound with Meguiar’s M67 first) only if the finish has oxidized.

#1
Best overall
Aero Cosmetics Wet or Waterless Wash Wax ALL kit (144 oz)
4.7 out of 5 on Amazon · 131 ratings · About $50 (checked September 26, 2026)
This is the product that made us stop dragging a hose around campgrounds. Wash Wax ALL is a water-based, aircraft-grade cleaner that lifts dust and road film while leaving a thin UV-protective wax, so you spray a panel, wipe it with one towel and dry it with another. It is safe on fiberglass, gelcoat, painted aluminum, decals, windows and rubber roofs, and because there is no runoff it is allowed at most parks that ban RV washing. The kit’s gallon plus a 16 oz spray bottle and four plush towels will handle several full washes of a 30-footer.
What we like
- No hose or bucket, so it works at campgrounds with wash bans
- Safe on decals, gelcoat, clear coat and ceramic coatings
- Cleans and waxes in one pass
Keep in mind
- Waterless washing is for light to moderate dirt; a mud-caked rig still needs a rinse first
- Wax protects but does not restore an oxidized finish (see 3D Speed below)
#2
Best bug & tar remover
ProSol Works Bugs N’ All multipurpose cleaner & degreaser (32 oz concentrate)
4.4 out of 5 on Amazon · 4,660 ratings · About $36 (checked September 26, 2026)
After a day on I-40 the front cap of an RV looks like a science project, and baked-on bugs will etch gelcoat if you leave them. Bugs N’ All is a concentrate you dilute in the included spray bottle; mist the nose, wait a minute and the bugs slide off with a soft sponge instead of scrubbing. It is non-toxic and non-caustic, so it is safe on paint, chrome, glass and decals, and the same bottle diluted weaker handles tar, tree sap and light black streaks. One 32 oz bottle makes up to eight gallons of cleaner, so it takes little storage space.
What we like
- Dissolves dried bugs without scrubbing
- Concentrate: one bottle lasts a season of travel
- Safe on paint, gelcoat, glass and chrome
Keep in mind
- You have to mix it (the 32 oz bottle is included)
- Heavy tar still needs a second application
#3
Best black-streak remover
Star brite Instant Black Streak Remover
4.5 out of 5 on Amazon · 619 ratings · About $44 (checked September 26, 2026)
Black streaks are the dirty rainwater that runs off the roof, awning rail and window frames, and they bake onto white fiberglass faster than you would think. A regular wash barely touches them. Star brite is made for exactly this: spray it on a cool wall, give it a few seconds and wipe, and the streaks come off without scrubbing. It is safe on gelcoat, painted surfaces and decals and will not strip wax, so it fits right into a normal wash day. It also handles exhaust soot on the back of a motorhome and scuffs on the entry step.
What we like
- Removes black streaks with a spray and a wipe
- Safe on gelcoat, paint, decals and existing wax
- Also cuts exhaust soot, grease and scuff marks
Keep in mind
- Costs more per ounce than a general cleaner
- Work in the shade; it streaks if it dries on a hot wall
#4
Best roof cleaner
Dicor RP-RC-1GL deep cleaning rubber RV roof cleanser (1 gallon)
4.6 out of 5 on Amazon · 2,719 ratings · About $18 (checked September 26, 2026)
A dirty roof is where black streaks start, and rubber roofs need a cleaner that will not dry them out. Dicor makes a lot of the roof sealants RVers already use, and this cleanser is built for the same membranes: spray it on, work it with a medium brush, and rinse. It lifts the chalky film, tree sap and grime that ordinary soap leaves behind, and it is the prep step Dicor recommends before a roof protectant or coating. Clean the roof two or three times a year and check the sealant around vents and the AC while you are up there.
What we like
- Made for RV rubber roofs; will not dry out the membrane
- Big gallon refill for the price of a quart elsewhere
- The recommended prep before roof coatings and protectants
Keep in mind
- Needs a rinse, so it is a hose-day job
- A roof is slippery when wet; use the ladder and take your time
#5
Best wash soap
Rain-X 620073 Spot Free Car Wash (48 oz)
4.4 out of 5 on Amazon · 8,773 ratings · About $10 (checked September 26, 2026)
When you do have a hose (at home, a storage lot or an RV-friendly truck wash), a pH-balanced soap that rinses clean matters more than any fancy formula, because water spots on a 12-foot-tall wall are impossible to reach with a towel. Rain-X Spot Free is designed to sheet water off so you can air dry, it will not strip the wax you just applied, and at one ounce per gallon the 48 oz bottle lasts a long time. Skip dish soap: it strips wax and dries out rubber seals.
What we like
- Sheets water so tall panels air dry without spots
- Will not strip existing wax or sealant
- Very concentrated and inexpensive
Keep in mind
- Needs a hose and bucket, so it is not for campground washing
- Not a degreaser: pre-treat bugs and black streaks first
#6
Best wash brush
Buyplus 5–12 ft telescopic flow-through wash brush with hose attachment
4.3 out of 5 on Amazon · 1,248 ratings · About $44 (checked September 26, 2026)
A flow-through brush turns a two-person RV wash into a one-person job: the hose screws into the end of the pole, an on/off switch at your hand controls the water, and the 12-inch soft-bristle head rinses as it scrubs. The aluminum pole extends from 5 to 12 feet, which reaches the top of a Class A sidewall and most roofs from the ground, so the ladder stays in the basement. The bristles are soft enough for clear coat; we still rinse grit off the head before starting so it cannot scratch.
What we like
- Reaches 12 ft, so most sidewalls and roof edges are done from the ground
- Water flows through the pole with a switch at your hand
- Soft bristles are safe on gelcoat and paint
Keep in mind
- Fully extended, 12 ft of pole is heavy at the end of a wash
- Check the hose gasket is seated or the connection drips
#7
Best for tall rigs
Aero Cosmetics Waterless RV Wash Wax Mop kit (9 ft pole, 144 oz)
4.7 out of 5 on Amazon · 519 ratings · About $230 (checked September 26, 2026)
The Wash Wax Mop is the premium way to use the same Wash Wax ALL formula on a big rig. The 15-inch pivoting head carries a wet pad on one side and a dry pad on the other; you spray a section of wall, wipe with the wet side, flip and buff dry, and the 9-foot pole reaches about 13 feet up. Aero says a 40-foot motorhome takes about an hour, and in our experience that is close. It costs more than everything else on this list, but it replaces a ladder, a hose and a lot of towels, and the kit includes a gallon of product.
What we like
- Wash, wax and dry a 40 ft RV from the ground in about an hour
- Two-sided head: wet pad washes, dry pad buffs
- Same decal-safe, campground-legal formula as our top pick
Keep in mind
- The most expensive item here
- The mop head is bulky to store in a small rig
#8
Best for oxidation
3D Speed all-in-one polish & wax (16 oz)
4.5 out of 5 on Amazon · 6,515 ratings · About $32 (checked September 26, 2026)
Southwest sun turns white gelcoat chalky and dull, and no amount of washing fixes that. 3D Speed is a light polish and wax in one: it has enough cut to remove oxidation, swirls and light scratches, then leaves a sealant behind, so one product does the whole job. Work a 2 x 2 ft section at a time by hand or with a dual-action polisher, wipe off before it dries, and follow with Wash Wax ALL or Fortify to keep the shine. Do the front cap and the sunny side first; that is where the chalk shows.
What we like
- Removes oxidation and swirls, then seals in one step
- Works by hand or with a DA polisher
- Made in the USA; no silicone dust
Keep in mind
- It is real work on a whole RV; plan a day per side
- Heavily oxidized gelcoat needs a compound first (Meguiar’s M67, below)
#9
Best for heavy oxidation
Meguiar’s M67 Marine/RV One-Step Compound (32 oz)
4.6 out of 5 on Amazon · 5,170 ratings · About $23 (checked September 26, 2026)
If the gelcoat leaves white chalk on your hand, a light polish like 3D Speed will not be enough. Meguiar’s M67 is a marine and RV compound made for exactly that: it cuts through moderate oxidation, stains and water spots on fiberglass gelcoat and brings the color back. It is the step before the shine. Work a small section at a time by hand or with a dual-action polisher, then follow with 3D Speed or a wax so the fresh gelcoat is protected. On most rigs you only need it once every few years.
What we like
- Removes moderate oxidation that polishes cannot
- Made for fiberglass gelcoat on RVs and boats
- Restores color on faded front caps and sun-side walls
Keep in mind
- It is a compound, not a wax: always follow with protection
- Real work on a big rig; a dual-action polisher helps a lot
#10
Best UV protectant
303 Aerospace Protectant for vinyl, plastic & rubber (32 oz)
4.7 out of 5 on Amazon · 27,657 ratings · About $28 (checked September 26, 2026)
Sun does more damage to an RV than dirt. The rubber seals around slides and windows, the plastic vent covers, vinyl trim, tire sidewalls and even the dash cracks and fades from UV. 303 is the protectant RVers swear by for all of it: spray on, wipe off, and it leaves a dry, non-greasy matte finish that repels dust instead of attracting it. Slide seals in particular last longer and stay supple when they get a coat every month or two in the Southwest.
What we like
- UV protection for seals, trim, vents, tires and the dash
- Dry matte finish; no greasy shine that collects dust
- Water based, with no silicone oils or petroleum distillates
Keep in mind
- Needs reapplying every month or two in strong sun
- Not for fabric awnings or unfinished leather
#11
Best quick shine
Shine Armor Fortify Quick Coat ceramic waterless detailer (8 oz)
4.3 out of 5 on Amazon · 95,120 ratings · About $13 (checked September 26, 2026)
Fortify is the bottle we keep in the door pocket for the tow vehicle, the entry door and the dusty lower panels between real washes. It is a waterless wash with a ceramic (SiO2) polymer that bonds in about 15 minutes, so water beads and dust wipes off more easily for the next few weeks. Spray, wipe with one microfiber, buff with another. It is not a substitute for a full wash on a dirty rig, but for a light coat of dust or fingerprints around the door it saves a lot of time.
What we like
- Adds hydrophobic protection in minutes
- Great for the tow vehicle, doors and lower panels between washes
- Cheap enough to keep a bottle in every rig
Keep in mind
- An 8 oz bottle does not go far on a 35 ft coach
- Use on a lightly dusty surface only; grit under the towel will scratch
#12
Best towels
HOMEXCEL microfiber cleaning cloths, 12-pack (11.5 x 11.5 in)
4.5 out of 5 on Amazon · 50,864 ratings · About $7 (checked September 26, 2026)
Every product above works better with a stack of clean microfiber, and a waterless wash goes through towels fast because you switch as soon as one gets dirty. This 12-pack is cheap, lint-free and color-coded, so you can dedicate green to bugs, blue to glass and so on and never drag bug residue across a window. Wash them without fabric softener (it kills the absorbency) and they last for years.
What we like
- Twelve towels for the price of one detailing towel
- Four colors make it easy to keep glass, wax and bug towels separate
- Lint-free and safe on paint and glass
Keep in mind
- Thinner than plush drying towels; buy a bigger one for drying a whole rig
- Wash separately and skip fabric softener
#13
Best space saver
Bettaclean collapsible bucket and outdoor scrub-mop set
4.4 out of 5 on Amazon · 420 ratings · About $36 (checked September 26, 2026)
A rigid five-gallon bucket is one of the most awkward things to store in an RV. This set folds the bucket flat for the basement, and the adjustable-handle scrub mop turns out to be the right tool for the jobs you forget about: the outdoor mat, the steps, slide toppers, the awning fabric and a muddy tow-vehicle floor. Fill the bucket with Rain-X wash for a hose wash, or use it to soak a wash mitt for the wheels and lower panels.
What we like
- Bucket folds flat for RV storage
- Scrub mop handles mats, steps, awnings and slide toppers
- Handle adjusts for taller users
Keep in mind
- The folded bucket does not hold as much as a rigid one
- The mop pad is not for painted walls; use the brush or a mitt there
#14
Best ladder
Soctone 10.5 ft telescoping ladder with stabilizers (330 lb)
4.6 out of 5 on Amazon · 180 ratings · About $100 (checked September 26, 2026)
Even with a 12-foot pole, some jobs (checking roof sealant, cleaning the AC shroud, reaching the awning arms) need a ladder, and the flimsy factory ladder on many rigs is only rated for a rooftop peek. This one retracts to about 34 inches with a thumb button, has two triangle stabilizer bars that cut the wobble, slows the rungs as they collapse so fingers stay safe, and holds 330 pounds. It fits in a basement bay or a truck bed. Set it on firm, level ground and keep three points of contact.
What we like
- Collapses to about 34 in. for a basement bay
- Stabilizer bars make it much steadier than a bare telescoping ladder
- Rungs retract slowly, so no pinched fingers
Keep in mind
- Around 25 lb; not the lightest ladder
- Ten and a half feet reaches most roofs, but a tall Class A may want the 12.5 ft version
#15
Best gloves
MedPride powder-free nitrile gloves, large (100)
4.7 out of 5 on Amazon · 104,891 ratings · About $10 (checked September 26, 2026)
Degreasers, bug remover, polish and rubber-roof cleaner are hard on skin, and a box of nitrile gloves is the cheapest protective gear you can carry. These are the ones that also handle the sewer hose, the propane tank and the greasy hitch, so we buy them by the box and keep one in the basement and one under the sink. Powder-free means no residue on the paint.
What we like
- A box covers washing, dumping, hitching and greasing
- Nitrile stands up to solvents and degreasers better than latex
- Powder-free, so nothing transfers to the finish
Keep in mind
- Single use; you will go through them
- Sizes run a little small; order up if you are between sizes
Step by step
How to wash an RV exterior
Six steps, with or without a hose. The whole routine takes about an hour on a 30-footer once the bug remover has done its work.
- Park in the shade and let the walls cool Hot fiberglass flashes soap and wax before you can wipe it, leaving streaks. Early morning or a shaded pull-through is best; if the wall is hot to the touch, wait.
- Pre-treat bugs, tar and black streaks Spray diluted Bugs N’ All on the front cap and mirrors, and Star brite Black Streak Remover on the streaks under windows and awning rails. Give it a minute; do not let it dry.
- Rinse from the top down Knock the grit off with a hose (or, for a waterless wash, dust the lower panels with a soft brush first). Grit is what scratches, not the soap.
- Wash one section at a time With a hose: Rain-X in the bucket, the flow-through brush on a 12 ft pole, roof line to bottom. Without a hose: spray Wash Wax ALL on a 3 x 3 ft section, wipe with a wet towel, then dry with a clean one, switching towels as they load up.
- Do the roof and awning carefully Rubber roofs get a roof cleaner such as Dicor’s and a medium brush, never a petroleum solvent. Check the sealant around vents while you are up there. Extend the awning, brush it with the collapsible-bucket mop and let it dry fully before rolling it up.
- Protect the finish Badly chalked gelcoat: compound with Meguiar’s M67, then polish with 3D Speed. Light chalk: 3D Speed alone. Then wax (Wash Wax ALL does it as you dry) or ceramic-spray with Fortify. Two or three times a year is plenty; in the desert sun, lean toward three. Finish with 303 on seals, trim and tires.
Before you start
Check the park rules. Many RV parks ban hose washing to save water; nearly all of them allow a waterless wash because there is no runoff. Big rigs that need a real rinse can use a truck wash such as Blue Beacon, which has RV bays at many locations.
Buying guide
What to look for in RV cleaning supplies
The four things that separate an RV-safe product from a car-wash-aisle impulse buy.
Know what your walls are made of
Most RVs have fiberglass with a gelcoat or painted finish; some older and lighter trailers have painted or bare aluminum. Everything on this list is safe on all three, but polish (3D Speed) is for gelcoat and clear coat, not bare aluminum.
Protect the decals
Vinyl graphics crack and peel when they are hit with solvents, strong degreasers or a pressure washer up close. Use a pH-balanced soap or a waterless wash over graphics, and keep any pressure washer at least two feet away on a wide fan.
Buy concentrates
Storage is the scarce resource in an RV. A 32 oz bottle of Bugs N’ All makes eight gallons and a 48 oz Rain-X makes 48; both take less room than one ready-to-use jug.
Skip the dish soap
Dish soap cuts grease, which is exactly why it strips wax and dries out the rubber seals around slides and windows. Save it for the sewer hose.
