What does GofX remove that a glass cleaner won't?

It targets bonded contamination: oil film, insect residue, water spots and old coatings. A regular cleaner mostly lifts dust and light grime.

Does it leave protection behind?

No. It cleans and prepares the glass. You apply a ceramic coating or sealant afterward for protection.

It is made for exterior glass surfaces. Keep it to the outside of the windshield and windows.

Work it onto clean glass with a pad by hand or machine, then buff off the residue. Several passes help on heavy buildup.

Used with a suitable pad and normal pressure, it is formulated for glass. Avoid grit on the surface and work in sections.
