Glass Compounds

A glass compound is an abrasive polish made for glass. Worked by machine on a glass pad, it takes out wiper arcs, water spots and light scratches that a glass cleaner cannot shift. The range is CarPro CeriGlass in a 250ml bottle and Sonax PROFILINE Glass Polish.

How to choose

• Check the mark first: run a fingernail across it. If the nail catches, the scratch is too deep to polish out safely. Haze, wiper arcs and etched water spots are what these compounds are for.
• Pad: use a firm pad from Glass Polishing Pads, because a soft foam paint pad does little on glass, which is far harder than paint.

Good to know

• Keep the pad moving and the glass cool: work a small area at a time and stop if it gets hot to the touch, as heat can crack a screen, especially on a cold day.
• Mask the rubber seals and trim around the glass first with Masking Tapes. Afterwards, clean the screen and protect it with one of our Glass Sealants.

Can you polish scratches out of a windscreen?

Light scratches, wiper arcs and etched water spots can usually be polished out with a glass compound on a firm glass pad. If a fingernail catches in the scratch, it is too deep to remove safely and the glass needs a specialist or replacing. Work a small area at a time and keep the glass cool.
