Rust on door sill panels...

Stainless steel is easy to clean. I suggest you try simple wd40 to clean it with a paper towel... this way, it doesn't scratch. If this doesn't work, then try some all purpose cleaner. Last resort if steel wool.

There should be a rust guarantee -- no silly comments please :-) -- from Merc. Won't the dealer deal with it?

Yeah, there should be, and there probably is, but it's not that bad, and if I can remove the stains without the hassle of a service appointment, all the better.

If not, I'll just wait until it has to go in for standard service and have it taken care of then. I can't imagine the dealer refusing to replace them.

Self-help may invalidate the guarantee as the problem would not have been dealt with 'professionally' as soon as known....
