Getting roof White Again??

[D_and_A_plus_6]

Got a 2nd TT, and roof wasn't been cleaned for several years and was pretty dirty almost black. I realize its not recommended, but took it to a car wash and between spray wand and soap brush, I was able to make it look better. Besides lots of Elbow Grease, any ideas of getting it whiter before I use the Thetford Rubber Roof Cleaner Condictioner? Thanks

Main reason I'd like it whiter/clean to reduce the black streaks doing down the side of the TT.

Thanks for all the info.

Fairly certain there is little difference between dirty gray and crisp white in regards to heat. Cleaning it isn't going to give you enough of a difference to justify the job.

The cleaner conditioner should finish the cleaning you are looking for.

Why do you want it to be white? Why do you want to put conditioner on it?

It needs neither.

Quite possibly your roof is black with a thin coating of white. Keep scrubbing and it will only get worse.

The only answer to your question is MAGIC ERASER. Get the regular not the kitchen ones with dawn in them. You will be surprised how little work, with no effort. My motor home is 24' and i used 6 of them. Took me about 1/2 hr. Gaurenteed you will be satisfied. Pm me if you use them, you will thank me.

Agree on the bleach. Make a strong bleach solution, spray on with a tank sprayer and let it sit for 10-15 minutes then hose off. I also like 30 seconds cleaner to remove mold, mildew and stains. The same company makes Spray and walk away which works over time.

X2 on the bleach. Don't let any straight bleach get on the roof as it will leave greenish blue streaks. I use awesome and bleach.

Put some Dawn or other soap in a yard sprayer along with a few cups of bleach. Spray it liberally on the roof and using a medium stiff brush clean the roof. Let it set for 20-15 minutes so the bleach can work on the mold and mildew. Reapply for tough areas or areas you may have missed. If it doesn’t come white, at least you know it’s clean.

Don't worry about it, only God and birds see it. LOL

While pleasing the eye, did your washing make the roof more or less water resistant/proof?

I have power washed my roof and made it better but under the maple tree, where the leaves have left their mark, even the power wash didn't get it clean.
I have also tried Soft Scrub with bleach which works well but one has to use a lot of it.
