I've been using Applegarde for a few years and decided to spray my mini white mc speedy about a month ago. I've never had a problem with the water/stain spray before so imagine my surpise when I picked up my mini speedy and there were horrible yellowish/tan stains all over the white mc canvas! I emailed applegarde a month ago and no response so far. Anyone have any hints or tips I can try to get the stains off? And has anyone had this problem before with white MC? Thanks!!
