Bilt-Hamber Auto Clay Medium is a professional clay bar developed to mechanically remove embedded contaminants – iron particles, brake dust, tree sap residue, and traffic film – that regular car washing cannot reach. The result is a paint surface with factory-smooth finish, ready for polish, sealant, or wax.

Auto Clay Medium is optimised for paint in normal to moderately contaminated condition. The clay is easy to knead and quickly forms a fresh clean working surface, making it efficient and time-saving in professional settings. See more Bilt-Hamber products for paint care in our range.

Unlike many competing clay bars, Bilt-Hamber Auto Clay Medium requires no expensive dedicated lubricant – ordinary tap water provides sufficient lubrication during use.

What is Auto Clay Medium and why choose it?

A clay bar works mechanically across the paint surface, shearing off contaminants embedded in the pores of the clear coat. Bilt-Hamber Auto Clay Medium has been ranked as the leading clay bar on the market for several consecutive years by the British trade publication Auto Express, and in independent tests has been shown to outperform both competing clay bars and modern clay cloths.

The product is developed to suit a wide range of vehicles and paint conditions. Because the clay requires no specialist lubricant, the cost per treatment is kept low – a clear advantage for detailing studios and reconditioning workshops operating at high volumes.

Frequently Asked Questions (FAQ)

Does Bilt-Hamber Auto Clay Medium work without a dedicated lubricant?

Yes. Bilt-Hamber Auto Clay Medium is designed to work with ordinary tap water as a lubricant. The paint area should be thoroughly wet during use – the clay bar should never be used on a dry surface. This means there is no need to purchase a separate lubricant, which reduces the cost per treatment compared with many competing clay bars.

How many treatments does one bar of Bilt-Hamber Auto Clay Medium provide?

According to the manufacturer's guidelines, one bar of Bilt-Hamber Auto Clay Medium is sufficient for approximately 4–5 complete treatments on a medium-sized car. Longevity is affected by the degree of paint contamination. To maximise coverage, it is recommended to pre-treat the paint with an iron remover (such as Bilt-Hamber Korrosol) before the clay bar treatment, so that the majority of iron particles are removed before the clay is used. Never drop the clay bar on the ground – grit and sand that become embedded in the clay can scratch the paint.

What sets Bilt-Hamber Auto Clay Medium apart from other clay bars on the market?

Bilt-Hamber Auto Clay Medium has been voted the best clay bar on the market five years running in independent tests by Auto Express, and has been shown to outperform both competing clay bars and modern clay cloths. A key differentiator is that the product requires no expensive dedicated lubricant – tap water is sufficient. The medium grade is optimised for paint in normal to moderately contaminated condition and is easy to knead, making it straightforward to quickly expose a fresh clean working surface.
