Front windshield of my 2017 Infinity QX60 had acid rain spots ingrained in glass. Tried white vinegar, glass polish, Windex, etc. without any success. This disc along with Ceriglass Polish was 100% effective in removing all spots in one attempt. Window is now like new and totally clear. GREAT products!!!

This worked perfect along with ceriglass to remove scratches out of my windshield.

It worked well with the CarPro glass polish.

Does not work at all.

It was okay, I had better results with a wool pad.

Works great, enjoyed the results.
