Mold and Dicor

[rlwhit]

Have had increasing amount of black spots on roof. I'm sure it is mold. Tried Dawn and Diror cleaner. No help. Sent an email to Dicor asking what to do. Within minutes recieved a reply. Very interesting instructions on how to remove mold. Wish I knew how to copy the whole thing. It came as an attachment done in Word. Tried the Control-C bit but to no avail.

The good news is that the mold will not damage the rubber. only unsightly.

Anyway told to use Tilex. Do only small areas at a time and be careful not let it get on things that it could damage. Let it stand 5-10 minutes than brush it. Rinse very well. Tried it and 98% of stains are gone. It is slow going but will be worth it.

White roofs are happy roofs.

Thanks for the information Dick, Tilex who would have thought of that, how do you keep it from running down the side of the Monty and if it does does it hurt the decals or gel coat.

Some additional information about using Tilex to remove mold from the roof can be found at the bottom of this page. Very interesting. Used carefully, it looks like a whiter roof may be in my future.

One word of caution if using the Tilex method or any roof cleaner. KEEP THE SIDES OF THE RIG WET!!! If the cleaner runs down the dry side of the rig it will leave a very clean streak that is very hard to remove. It is usually hot up there so have the wife hose the side and you down occasionally, but keep it wet until any chance of the roof cleaner dribbling down the side is gone... Dave

"Awesome" will do the same thing, HOWEVER, as Dave says, you need to constantly be rinsing the top and sides as you brush. I also used the "Clorox" brand of spray cleaner, which is bleach, and it did a fine job also, BUT again, and I can't emphasize enough, Keep it rinsed well and it will look almost like new when done......Of course, no one sees it but you, or the guy next door that stands on top of his RV checking others out.....

Below is the information from Dicor that rlwhit received. Enjoy!

CLEANING MOLD AND/OR MILDEW FROM RUBBER ROOFING

MATERIALS NEEDED:

• BUCKET OF WATER
• SPONGE
• MEDIUM BRISTLE BRUSH
• TILEX BATHROOM CLEANER (MOLD/MILDEW)

TILEX BATHROOM CLEANER (MOLD/MILDEW)

There are no ingredients in EPDM rubber roofing that will promote the growth of mold and/or mildew. Atmospheric dirt, shade, sun, humidity and moisture are some of the contributing factors that form mold and/or mildew. Regular cleaning of your rubber roof will help prevent mold/mildew from forming on the EPDM roof. Dicor recommends that you wash your roof an average of 3-4 times a year using a non-abrasive cleaner (Dicor Rubber Roof Cleaner RP-RC160C concentrate or RP-RC320S ready-to-use) and a medium plastic or nylon brush.

Mold/mildew on your EPDM roof is simply a parasite that attaches itself to the roof and grows – similar to bathroom mold that grows in your shower. It does NOT attach the membrane but is unsightly and if allowed to grow will discolor the roof completely and may become a stain that cannot be removed.

Please note the removal of mold and/or mildew is not a job to be rushed. Allow ample time to complete the job and follow the instructions carefully. Although the products mentioned will not harm your roof, if you do not follow the instructions, other areas could be affected.

Tilex is a bathroom cleaner that can be purchased at many grocery stores or discount stores. Tilex contains strong chemicals. Please read the label thoroughly. Tilex should not come in contact with painted or aluminum surfaces. If it drips over the sidewalls or comes in contact with painted or aluminum surfaces, wipe immediately with a damp sponge.

WORK WITH A SMALL AREA in order to maintain the control. Spray a small area approximately 2’ x 2’ with the Tilex. Allow the Tilex to remain on the roof for 3-10 minutes per area. Scrub with a medium bristle brush. After scrubbing, wipe with a damp sponge.

When finished with whatever time frame you intend to spend on the roof (whether you do the entire roof or just a portion) rinse the roof thoroughly with a garden hose. BE SURE TO RINSE WINDOWS AND SIDEWALLS ALSO.

Most often one application is all that is needed to alleviate the problem. Depending on the amount of mold and/or mildew and the length of time growing, more than one application may be necessary.

Follow this procedure with the Dicor Roof Gard (RP-RG320S) protectant.

05 3500 has almost black spots on the lengthwise rubber molding...think that Tilex could work on that? Have tried numerous cleaners and methods with only limited success. It is worse on one side of camper.
