Cleaning the roof

[Eagle]

When I got the camper out this spring, the roof looked nice and clean although I didn't scrub it prior to putting it away for the winter.

Last week when replacing two gutter spouts (cheap plastic gets hard in the sun) noticed the roof looked really dirty and had 'sap spots' that collected dust over the summer.

Yesterday decided to clean the white rubber roof. What a job! It's TPO with a textured surface, not smooth. I used "Best rubber roof cleaner" and a long handled car wash brush. It removed "some" of the dirt but left the roof a dull grey and the dark black 'sap' spots.

So, down on the hands and knees with a hand scrub brush and worked away hand scrubbing the vent covers, antenna, A/C cover, etc. The frig vent would NOT come close to returning to white.

About 1/3 of the way done, ran out of BEST cleaning product - local camper store was out of stock or ordered some, to be here Friday.

I use this: https://www.amazon.com/B-S-T-55128-C...0359024&sr=8-3

But what a PITA to clean.

What product do you use and how well does it clean?

Mop on dish soap and water. Hit it with an electric pressure washer 25 degree nozzle about 6” away. No scrubbing and white as snow. Same as you would a rubber roof on a building.

My pressure washer puts out 1,600 PSI - either hot or cold .... might be a bit much?

Whenever I clean the roof I always follow up with a spray on roof UV protector. Not sure how much it helps, but it gives me peace of mind.��

I have a cheapo Harbor Freight pressure washer that works great on the roof after a light hand washing. Not too much psi/gpm.
And yes on the UV stuff afterwards. Use it on the tires as well.

Mine is 2030 PSI. No problem at all with a 25 Degree nozzle. Just stay off the Dicor.
