Hello Readers!

Has anyone used a product called Wet and Forget on an EPDM roof for the mold/mildew.  It states it is noncaustic, no bleach, can be used on 'rubber' among A LOT of other products.     We used it recently on our vinyl home in the Carolinas for the green mold on the north and northeast sides, and WOW! it did a wonderful job, green is gone.  Also cleaned the gutters and aluminum decking that was an overspray.  Supposed to fight the mold/mildew/moss/algae from returning - so time will tell.   Here is Amazon's link, and if you scroll down a ways, there is quite a product description.   https://smile.amazon.com/Wet-Forget-800003-Mildew-Remover/dp/B001GTRBMO/ref=sr_1_fkmr0_1_m?ie=UTF8&qid=1498857085&sr=8-1-fkmr0&keywords=Wet +'n+forget#Ask

If anyone answers, I'll just say "Thank You" in advance!

Interesting... I will have to sift through the 1460 reviews of it.  I wounded if it would effect the wax on the rig as the rain washes it off.

I am looking forward to see if anyone gives feedback on here.

We were thinking of it for the roof since it acts on mold, algae - but not on 'dirt'.  Some people felt it should clean the dirt on their home and rated it one star because it did not work for them.   We actually had the chemical stored since last year - never got around to using it, so wondered about the expiration of the it, but no, no problem.  You put it on a dry surface (no dew, nada) and let the rain activate it.   You do not have to wash the surface first - and we had plenty of pollen on top of the mold, a real mess.    We saw the green mold on our vinyl house start to go into little balls and it took a few rains from various directions to get under the eves, etc. but - tada!  it is all gone, and we're believers in this stuff.   So now we wonder, will it stave off mildew, mold, etc. on EPDM roofing, spray it off before it starts?  Would be great if you just sprayed this stuff on once a year and didn't worry about black blotches appearing on the rubber. 

Instead of spending more money, I use 2-3 oz bleach in my 5G wash water bucket. This kills mold and mildew on the exterior of the RV and awnings, including those pesky black spots on vinyl trim and the roof membrane.

Hi Ray,  We're not full-timers yet, and I know I don't get out there and wash the trailer often enough, and I really don't feeling comfy walking on the rubber roof(my quirk) -- hence, it doesn't get washed as it should.   This W &F product gets re-activated by moisture/rain.   We remain amazed how algae-free our house is, as we are experiencing one of the rainiest spring-summer seasons in a long time; everything is staying soaked, windows fogged up day and night.  I have not been able to get an answer from the manufacturer to date about EPDM.  Every Spring or Fall my husband would be on a two-story ladder with bleach/soap/water/brush/hose scrubbing the house,   It's been months and not a speck of green has returned.  If we can spray once a year, we'll be delighted.... and that's what I was hoping about the EPDM roof.   Thanks for jumping into this topic.

Epdm roofs caulk. Houses don't. If you don't remove. Caulk it will streak the sides of your camper. 

I agree with   mysticms  I believe in Wet and Forget.

Over about 10 years,  have done power wash and the apply Wet & Forget and I have just applied Wet & Forget over the green. Both methods have worked on vinyl and metal siding.

I tested it on Tombstones by just spraying on with no cleaning. A year later I inspected and compared pictures. The results where good, the stones was shiny again if the tombstone less than 5-7 years old. Returning to stones 11 years old or older required additional labor to clean the mold.

I haven't heard of any results on the EDPM roof material. Would be interesting to find such a RV in a junk yard with green to test

   That's good news from you since you have been using W&F much longer than we with positive results.  I was thinking about the same:  if only someone had an old trailer parked and would do a test patch for the club.  Perhaps I should have posted this under General rather than Housekeeping to begin.  I think there would be a ton of happy campers out there if this stuff could be sprayed on the roof,say once a year,  and it did the battle of the mold/mildew/algae, even if one still had to rinse the road grime from time to time.   As the one writer mentioned, the roof will still chalk.     Thanks for the tombstone application idea, as we have our pet cemetery here at home - and under pines, the granite is green.  I was told to use vinegar and water solution, but no more effective than soap and water.

Thanks for adding to the conversation.

Watching this post, I use wet and forget 2x a year at my house (I do the roof, all concrete and deck) and the results are amazing, talk about making a roof look new again!  I simply hadn't thought about spraying it on top of our ugly dirty RV roof, now I'm wondering why I hadn't thought of this.

The caulking will streak the sides of your camper. I see no way not to regularly wash it to prevent it unless you seal it.

Impressed with what you do for home maintenance and very encouraged with your results.   So, do you want to be a test roof for the Escapees and Wet & Forget?!!!  Uh, I'm half joking.   Anyone brave enough to do a test patch on an EPDM roof on a no-longer-used trailer?

Thanks for your comments.

Hi Glenn, this Wet and Forget is like a stain and growth (algae, mildrew, mold, moss) remover - and then it keeps the stuff from growing back as rapidly.  I don't think it does a 'sealing', but it may help make washings easier on a trailer roof, maybe less frequent washings, and most likely less scrubbing when it comes to those black blotchy patches we get on EPDM.  I'm encouraged others have found this product long before I and continue to use it effectively.  We just need a test roof  w/before and after pictures!  I'm guessing it would be fine on Dicor caulk and I think  I'm going to try some on the caulk on one of our trailers, which would be more pleasant than turpentine, although  the turp works really great w/ great whitening powers.  It just MIGHT, "MIGHT" stop caulk from streaking, just like we won't know unless we try if the chalking MIGHT stop on the EPDM.   Okay, are there any chemists out there, we could use one to jump in here, please! 

I did the roof of my BT Cruiser with amazing results, it still looks great.  I just re-applied yesterday and decided to do the entire awning, side walls, etc.  I can't say enough good things about this product (not affiliated in any way).

Husband just reapplied W&F to our vinyl siding on house after 3 years, and I must add we have had continuous wet weather for over a year as well as warmer-than-'average' temps that aided the growth of green mold. We were impressed it lasted 3 years on the house before needing to be reapplied.  Husband washed house this time before applying W&F, but had done no prep the first time W&F was applied.
