It’s one of those questions that crops up after a good morning’s wash of the car. Swirl marks. What do we do about them? Or perhaps we should ask: where do they come from?

The fact is this. They’re near nigh unavoidable. No matter how new and how fine your microfibre cloth is, the fibres themselves will cause a surface effect called micro marring. Yes, the finer the cloth the finer the fibres and the less effect they’ll have but they will mar the surface and it’s more noticeable on older paints.

Another key cause is the polish used. A good analogy is sandpaper. They have what’s called a grit number. The higher the number, the finer the grit, and the less damage, if you will, it’ll do to a flat surface.

Swirl marks are also more obvious on darker painted vehicles. This is nothing more than contrast between the sides of the scratch and the surrounding surface.

There are different methods of polishing a car. There’s using a mechanical polisher and in the wrong hands can do irreparable damage. Hand polishing is more labour intensive but far less prone to causing permanent damage. Using the wrong type of polish for the intended end result is also a cause of scratches and swirl marks.

NuFinish offers a product to help look after reducing and potentially almost removing swirl marks. An easy to remember name, Scratch Doctor is best used on new, washed, microfibre cloths. Washing ensures that any potential particles of dirt or left over manufacturing residue is removed and won’t impact the surface further.

After washing the vehicle to be treated, and dried with a clean chamois (it’s about cleanliness too), a small amount should be applied to the microfibre and applied to the area that’s affected. It’s here that a critical part of the process comes into play. A simple few rubs won’t be enough, it must be rubbed in thoroughly. It must then be left to dry until a haze is visible. Another microfibre cloth should be used and with light to medium pressure, clear the area until the haze has been removed.
