you in Edmonton? Go to Fibreclean on the south side they can set you up.
Have you tried Babes? I've had really good luck with that. You have to be careful with the magic erasure as it is an abrasive ( even though it doesn't feel like it), it could take the finish off of the vinyl.
Anytime I've had to clean the upholstery in my boat, I've used Spray 9 and a coarse bristle scrub brush. Haven't had a problem getting anything off yet.
Try a magic eraser, they seem to work on almost anything
Tks for the info. no haven't tried Babes. Is that something available at Canadian Tire?
