Hazing on XPEL clear bra
I have an XPEL clear bra installed last summer. Now after a winter of driving there is a haze on the bra that will not wash off. I've tried regular car 'shampoo' and Dawn dish detergent. It's still there. I rubbed a dry microfiber cloth on a very small spot quite hard and was able to get it off, but I'm afraid I'll ruin the bra (and it will take forever) to do the whole front end.
Any advice on how to safely remove it? Anyone else have this issue?
I've attached a pic showing the hazing.
