Cheap Tire Foam

[BlackCadi14]

I used X product (Hot Tire Foam) and now I got black spots on Wife's running boards, I was able to get spots off car, how do I get the spots off running boards?  The vehicle is a Chevy Tahoe 2007

I use a different tire shine for now, will try Adams once this product is done with but I do use Adams foam pad to apply it with and it does great.

Are the running boards plastic?

If you have Adam's Tire & Rubber cleaner you could try that. If not, try any strong APC with a microfiber towel that you don't mind getting dirty.

What Chris said.  Tire & Rubber Cleaner or APC and some elbow grease should get them off.  Don't be afraid to scrub hard.  You might have to.

Yes they are black plastic ones, I have Adams Eco Cleaner, I can try that to see if I can get them clean.
