Well, we have tried things that should probably never be used on an RV and so far nada. Ronda is out buying magic erasers and WD-40 since I can’t find my can.
If that doesn’t work I give up, I will have thrown everything but the kitchen sink at it. I’ll try and come up with a list of things I tried later.
We’re getting the rig cleaned up for our last trip of the season…. more to come soon!
