Koch Chemie Clay Bar Heavy

Koch Chemie Clay Bar Heavy is a more aggressive option for deep surface cleaning. Built for heavily contaminated paintwork thats due for polishing.

The Heavy Clay Bar from Koch Chemie is a high-strength car clay bar designed for tough jobs. Its made to tackle deeply embedded contaminants like overspray, road tar, brake dust, industrial fallout, tree sap and rust bloom, particularly on neglected, weathered or older finishes. Its intended for vehicles that are going to be polished afterwards, where the priority is maximum cleaning power rather than paint safety alone.

Its abrasive formulation means its not suited to new paintwork or surfaces where correction is not planned. But when used correctly, especially with a proper clay bar lubricant like Koch Chemie Clay Spray, it makes short work of contamination and preps the surface for serious correction or coating work.

Use it on paint, glass and other smooth surfaces where bonded grime has built up. Youll feel the difference straight away. It has real bite, but stays consistent and predictable during use. For detailers working on daily drivers, commercial vehicles or paint thats been neglected, this bar saves time and gets results fast.

If youre after something gentler for soft clear coats or coated cars, the Koch Chemie Clay Bar Mild is a better fit. But when aggressive decontamination is needed before polishing, the Heavy Clay gets it done.
