How The Heck Can We Remove The Black Spots On Our RV?

How to Remove Black Streaks on an RV

How to Remove Black Streaks on an RV

Pictured Above: AutoRight Easy Wash Stick

The Class C RV we own, we purchased last summer. This spring I am beginning to really detail and clean the RV for the summer and I naturally want it to look as good as possible. There are rubber gaskets/seals around all the windows of the RV that have black spots (almost looks like mold) on them (similar to what you might see on the roof).

I have tried everything I can think of to remove this to no avail. (Purple Power, Grease Lightning, Bleach, RV Black streak remover, Magic Eraser Pads, Roof cleaner, etc) Is there something that will restore these to their glory days? It is the only thing that looks bad on the RV and I am afraid to have them resealed with new ones since they currently don't leak just to improve the looks. Don't fix it if it ain't broke as my granddaddy used to say.

ANSWER: Hi Jason, welcome to wonderful world of getting rid of black spots on an RV. I am sorry that you have used so many products without success. Part of the problem may be that someone may have applied wax over the black spots which does not allow the cleaners to get to the actual stain.

That being said, I do not have a recommendation for any product that I can guarantee will remove the black spots. All I can do is convey to you what other RVers have used with success.

DISCLAIMER: Since I have not used any of these products personally I cannot tell you if they actually work or even if they could cause damage to your RV's finish. So it is up to you to read the labels of these products. I would not use any of these products on or near any decals on your RV.

I would also try the products on a very small area of the RV to see what happens before attempting to use it on the whole RV.

Here are some of the products that some RVers swear will remove black streaks and spots; AWESOME, Spray & Wash, Castrol Super Clean, Dow Scrubbing Bubbles Bathroom Cleaner, a diluted solution of Tide Laundry Detergent and some RVers even use WD-40 to remove black streaks and spots.

Hope this helps.

AWESOME


We have a fiberglass camper that has a lot of black spots that look like mold. The RV place said nothing will take it off. I read the articles and went to our local Dollar Store an bought AWESOME and Kaboom, I had Goo Gone. I tried them all. The Goo Gone did nothing. Kaboom took to much product. The AWESOME worked with a little elbow grease and a very worn-out green scrub pad. I wish I could post pictures. It’s amazing how it looks.

Awesome Cleaner Degreaser

I have tried many of the commercial products with little success and way too much work. On another forum, I saw where someone recommended Awesome Cleaner Degreaser which you can buy at Dollar General. Truly an amazing product and have been using it for 2 years! Wet, spray-on, nylon brush takes it all off.

Spray-on engine degreaser works great to remove black streaks. Spray on; wipe off. Clean with spray-on wax to restore the finish and remove the yucky smell of the degreaser.

Goo Gone

I have tried multiple ways to remove black marks on our RV. Today, I tried Goo Gone for the first time. It definitely won’t be the last time, it worked perfectly! No need to scrub, just sponge off.

Totally Awesome

I tried what seemed like everything. The one product that works for me is LA's Totally Awesome. I buy it at the Dollar Tree. Yep, $1 a bottle.

I caution you that it worked for me. It will leave a residue so going back over it with clear water is a must. It is a strong cleaner but I haven't had any issues.

Use at your own risk.

clr mold and mildew

Today I used a product called clr mold and mildew. Wow 8 bucks did my front to my back of the rv. I used it right out of the spray bottle on to a watered wall. I scrubbed by hand but not hard. It looks amazing. I will wash it again well this time roof and the walls again when I come back from camping. I didn't need pressured washer or anything. Great stuff

Mix a bottle of hydrogen peroxide with a cleaner like Kaboom, or your favorite. Apply wih a spray or even a lawn sprayer. If the spots are mold or mildew the peroxide will kill it. The soap will make the water wetter so it clings to the wall. This is less abrasive than using soft scrub or other harsh cleaners. Also you can use Bonami or Bar keepers friend as an addition to the solution.

Hi Guys, I live in North West Washington and on my aluminum siding I used Tilex Mold & Mildew Remover "NOT" Tilex bathroom cleaner. and on my Fiberglass I use Simple Green both of these I spray directly onto the trailer its self, right onto the problem area and then I spray my car brush with it and it really comes right off.

When you open your awning in spring time and it's covered with mold spots use the Tilex Mold and Mildew and the car brush, I spray the awing and then I spray the car brush, brushing the entire awing and then rinse with a hose on all of it. I have ruined many shirts in the process with the bleach:) Thanks Jay

I use Lysol Mildew and Stain Remover. It's hard to find cause not many places carry it. Walmart has it occasionally. I guess it's just too potent for them to carry, but I love it....

starstarstar 		Read cleaner instructions
by: pacamper.com

I have yet to find the perfect cleaner to remove those horrible black streaks.

What I can say however is that to be sure and read the instructions on the back of the cleaner. this is something I learned the hard way.

thinking Purple Power wash would effectively remove the black streaks(which it didn't), I immediately began washing my camper. What I found was what I thought to be soap residue on my RV windows. So, I began the rinse process again - same results. Turned the container over and it clearly stated to not use on windows.

At first I was upset with Purple Power wash but the mistake was my own. So my advice is to KNOW what you're using before you make the same mistake as I.

There is a product sold at Family Dollar store called "Awesome" it will remove black streaks. But you will need to re-apply wax. Another product that will remove black streaks is "GOJO" hand cleaner. The regular GOJO without the pumis works great. I have personally used both!
