Up on the roof

I took me about two weeks to replace and clean around all of the vent and A/C covers on the fifth wheel. I tried several different cleansers around the vents before I installed the covers. CLR with mold and stain remover whitened the old rubber roof the best so I used it on the whole roof. Makes the roof look about five years newer again. I used it with a tire and wheel brush around the vents and then a bigger brush-mop on the rest of the roof.

You can use a gas powered pressure washer, just make sure and use the black tip which has a larger opening and lower pressure, drop the pick-up wand on the pump outlet into your cleaner,when the cleaner runs out, now you are rinsing with plain water.

I have pressure washed my roofs every spring for years with a gas powered pressure washer using the yellow nozzle. No problems with it, it's enough to clean the dirt off and make is sparkly again but doesn't hurt the caulk. The only way you are going to hurt the roof/caulk is if you are irresponsible and let the tip get to close. If you hold it 18-25" away you have nothing to worry about. I sprinkle powdered laundry detergent on, wet it, scrub it with a long handled brush, and pressure wash any stubborn spots. If you are lazy skip the detergent and just use the water. The key is to not use the fine red tip, that will tear wood up and wreck everything. The yellow and white tips are much less psi and do a great job.

While I do like a clean roof, a clean roof makes for clean sides, there is no way for using harsh cleaners never mind a pressure washer.

What cleans the roof is the same stuff that cleans the sides, the Meguires auto cleaner, or similar, in the pink bottle & a soft brush. It then gets a wiping down with 303.

I took a pressure washer to my rubber roof and did some damage to several areas of the roof. Indeed, you need to be very careful of letting the nozzle get to close to the rubber fabric because it'll peel. A learning experience and spent another day on the roof patching and caulking.

Strong cleaners on the roof washes down the sides of the trailer. I always do a wax job afterwards.

I have lost track of how many times people told me that and said THAT IS CRAZY MAN! and now they are doing it as well:B but after 3 5er's and 10 years of 3 times a year of doing the Electric power washer with no damage ya think I would have done damage by now AND I do the top of the Awning while I am up there Again the key is ELECTRIC power washer it does not even come close to taking caulking off or lifting the rubber roof off I would NOT use a gas 4-5K P.S I. washer That would be Crazy ,my Neighbor has been doing the same thing for years like I have if other folks want to spend a few hours scrubbing with cleaners and brushes have at it I got better things to do,believe me try it and you will never go back to Scrubbing and love the results:)

X2. The pressure will do its best to lift the roof material.

Man I agree CLR would not be a good choice IMO and you put alot of work into it to boot, for the last 3 5er's I've owned I just use a ELECTRIC 1700 P.S.I. power washer and it takes most stains out Pronto and makes roof cleaning a 1/2 Hr job ,Electric power washers work great because they are just powerful enough to clean the roof Without removing any Caulking

That is the last thing I would use on a rubber roof.

My roof isn't...cleaner than your roof. Will use a mild soap next spring prior to maintenance.

I guess a sparkling white roof is desirable, but I would be VERY hesitate to use CLR on an RV roof. CLR is super strong stuff.....lots of warnings about where and on what to use it.
