By big ass, size 13 shoes leave scuff marks on the black plastic door sill when I get in and out of the Stook no matter how careful I try to be about it. Anyone have a good cleaner that will get these out. I haven't found one yet.

 

I have tha same problem. I'd be interested in finding a good cleaner too. Right now, I use One Grand Vinyl cleaner, but it doesn't seem to remove the scuff marks entirely.
