Cleaning White Interior
LOL if you want to. I use a multi-surface cleaner on the vinyl making sure that I wipe it dry. I follow with a cheap suntan lotion (w/o alcohol) rubbed until dry.
One of my B-I-L is a PhD research chemist specializing in plastics. I asked about my practice that it wouldn't hurt the vinyl and that possibly the uV protection in the suntan lotion might help. He was the one who steered me away from lotions with alcohol because it does dry out the vinyl.
