The Automotive Clay Bar is an engineered mixture of resins that auto detailers use frequently to remove contaminants and pollutants from the car’s paint, glass, fiberglass, and metal.

The clay bar is used to remove dust, dirt, industrial fallout, acid rain, and other contaminants from your car’s exterior surfaces. The Clay Bar Detailing process removes the contaminant particles that stick to the clay when it is rubbed along the car’s surface leaving the surface smooth as glass. It is considered as one of the most important parts of detailing.

The Clay bars can be bought as mild, medium, and aggressive. Used as per the condition of the surface to be restored. Mild and medium being the most user friendly for the novice user.


The clay bar needs a lubricant in order to slide across the surface with medium pressure, (not in a circular motion) the lubricant can be a quick detailer or a shampoo. Sliding it side to side and then top to bottom sort of in a hashtag motion, covering the whole surface. If it sticks to the surface it needs more lubricant, every couple of minutes it needs to be folded over so that the contaminants that have been removed do not scratch the surface. It is important not to let it fall out of your hand on to the ground, as this will contaminate it and it should be discarded as the contaminants attached to it will tend to scratch the surface.

A 50 gram clay bar is good for claying 3 to 4 cars, if you cannot find a clean part in it, it is time to go for a new one. Some clay bars come in 200 gram size, it is always better to cut them into smaller pieces.

The new age Clay Bars are made from synthetic material, that have advantages over the conventional ones. One of the major ones is that if you drop it you can wash off the contaminants. The synthetic mitt or pads are also available. The pads can be used in dual action polishing machine at low RPM with a suitable lubricant.
