Once you have washed your car if you let it air dry or drive it around the block to “dry” it, you will get watermarks, especially if you live somewhere with hard water. Water marks are caused by mineral deposits that leave the outline of a drop of water on your vehicle’s paint. All water has minerals, whether it’s from the tap or the sky. As the water evaporates the minerals remain on the surface and create water spots.
Instead, get a cloth or towel to dry off all the water.
Drying is another big culprit in scratching or swirling your car paintwork so care is needed.
Even after a good wash a car can still have some small bits of grit left on it. Even if you are very careful and certain you have got it all off at the wash stage, it can simply drop out of the sky while you are drying!
When working on your car, you should really only be using one type of cloth and these are called microfibre. They are very absorbent and soft and will leave a clean bright finish. They are also used to clean glass, as well as lenses for glasses. They do not scratch, and are the best for your paint.
A chamois can cause more damage than a microfibre cloth because the microscopic bits of grit are trapped between the surface of the chamois and the car body work (similar to a sponge) and so tend to get ground into the body work.
When using a microfibre cloth these tiny, damaging particles go into the microfibre weave and away from the paintwork. Dedicated car drying microfibre towels can absorb more water than a chamois. Just be sure to wash the microfibre cloth carefully after use to remove any embedded grit and be aware that fabric conditioner should NOT be used.
Microfibre is commonly made from a mixture of polyester and polyamide. Ideally you should be looking for a drying towel that is labelled as a blend of somewhere between 70 to 80% polyester with the rest polyamide. Signs of a good towel are a non-scratch edge and a sticker label as ripping a sewn in label off can leave a rough and scratchy edge.
