I’m restoring a 78 Chevy stepside, and trying to stay mostly stock appearing. The original steering wheel is in good condition except for being extremely sticky, almost like the backing of adhesive sandpaper 🙁 . I’ve read and tried different things, like cleaning it with WD-40 and it stays OK for awhile, then it seems to get sticky again. I’d really like to keep this original wheel and wonder if anybody has ever dealt with this problem and how or what did you do to clean it. Thanks for any advice..
