Rubber roof cleaning black mildew stains

I have a 99 Fleetwood Flair with a 3 year old rubber roof. Last year I washed the roof with car washing soap, and applied protectant. Today I washed the roof but found quite a bit of what looks like mildew stains in various places. They didn't wash off with the car washing soap. I am tempted to use a mild solution of Javex or Clorox to get rid of the mildew, but I am afraid of damaging the rubber material. On the other hand, I am afraid the mildew is feeding off the rubber and will do even more damage than Javex in the long run. Suggestions?
Thanks for all responses.

Yesterday a guy with Country Coach said he sealed his with Mop&Glo yearly. Never used it myself.

Try Simple Green full strength on the spots and see if that works. Then wash it down good. I have been able to remove tree sap off my roof but mine is fiberglass. Make sure when you use anything on the roof to wet down the sides of your rig first to thin out any run off and then rinse the sides good.

Are you sure that it's not the EPDM backing'? The actual white is a sacrificial coating that eventually washes off in rain or scrubbing. If indeed that 20 year old roof has live its life, you will either need to replace it at a high cost or use one of the new 'wonder' products to coat the base material. Been there once before myself.

We use a power washer on our roof once a year with no chemicals. The TPO roof and EPDM slide replaced roof both come out clean.

Ok, I managed to clean 97% approx. Of the mold stains using increasingly stronger water/clorox solutions, almost 100% pure clorox at the end. Used a bottle sprayer, to contain any overspray, and ran lots of water to flush it all out, including lots of water on the sides to prevent streaking. The heaviest spots of mold were located where the tv antenna used to be. I did remove the antenna and we use a $40. flat indoor antenna from Walmart with better success. I applied epdm protectant to the roof, so I am done for 6 months.
Thanks for everyone's help.

Oxy-Clean. The best rubber roof cleaner. Put it on good and hot let it set for 20 minutes or so then rinse off.
