66 Caravel--I am finishing up interior renovation. The bathroom is in good shape and just need a good cleaning of the walls. There are some scuff marks as well as being generally dirty. Has anyone found a good product for doing this? The owners manual says use soap or detergent only--"never use scouring powder". But also says "Wrights Silver Cream is an ideal cleaner for the plastic lavatory and skirt". Anyone tried that? Wondering if there are new products since 1966
that might be effective.
