What is Clay Bar (Paint Decontamination)?

It is used after washing and before polishing. A lubricant is needed. Paint feels smooth afterwards. Clay mitts and towels are faster alternatives to bars. Light polishing afterwards removes any marring. Iron fallout removers can be used before claying to dissolve metal particles from brake dust and rail dust, which makes the clay last longer. Most cars need claying only once or twice a year.

How it works

The clay picks up particles sitting on the surface.

Why it matters for your car

Clay can leave fine marring. Discard dropped clay.
