I had an very unfortunate event yesterday - a can of insect repellant (30% DEET, by Sawyer) leaked in a bag, and soaked through onto my Roadster's passenger seat. This is nasty stuff - it damaged my binoculars, the bag, and worst of all, the seat. The stuff seems to have an ingredient that makes rubber, plastic, and apparently, leather seats sticky and discolored. My black leather now has a blotch of grey and is a bit sticky. I called Tesla, who suggested leather cleaner, but it had no effect I could detect. I also tried Dawn, since I think it is the oils in the stuff. Also no difference. If anyone on this forum has experience with this, I would be most grateful for any suggestions. TIA! P.S. - too late for me, but never let this stuff anywhere near your vehicle!
