Reddit reviews Gordon Glass Cerium Oxide - 8 Oz with 3" Felt Polishing Wheel

I'll give it a try, but I'm just about to pull the trigger and buy one of these from Amazon. Reviews are pretty good. On these cold misty mornings my wipers just aren't cutting it. Been tailgating every gravel truck I can find in the hopes of getting a bad chip.

I've already tried regular window cleaner, meths, auto window cleaner and glass scrub. Honda service tech said "yeah, that'd drive me nuts too but if you've already replaced the blades I don't know what to do."

Not quite the right sub, we deal predominantly with glass art however, there is something that may work if the scratches are not too deep. Cerium Oxide Powder can be used as demonstrated on This Page to polish glass. You don't necessarily need an expensive electric buffing tool if they arent deep it will just take some elbow grease. Alternatively if you have an electric drill you can get Buffing Wheels and Cerium oxide powder combos as well

All things considered though I'd first contact the manufacturer and ask about warranty options for a broken (smashed not scratched) jar or if they can supply you with a new one and at what cost. sometimes the manufacturers will really stand behind their products no questions asked. Had huntington Beach send me 2 new crockpots because mine went bad after only a year, never hurts to try.
