The walls on my busses interior is looking a little yellow in places, age or possibly the adhesive coming through. Has any one tried a vinyl spray to freshen it up? There's a few products on the market, I've sprayed seats in the past which turned out well but don't know whether it will work https://www.vinyldye.co.uk/All-Vinyl-Dye-Color-Sprays/Brillo Vinyl Spray Dye Mist
Carnt comment on that spray stuff but a few years ago I used jif or cif I think it's called now. Did quite a good job but did smell a bit funny for a few weeks but it certainly took some of the discoloration out of the Walls/ headliner just check a small area before doing the lot Sent from my SM-J500FN using Tapatalk
