Under a winter layer of dirt small scratches often disappear, and salt and filling brick spoil appearance of elegant wheels of your car.

Three factors are pernicious for aluminum disks: metal raid from deleting of brake shoes, salt and even insignificant blows about a border of sidewalks.

Let's begin check of wheels with their thorough sink and cleaning. For aluminum disks there are special cleaners which are applied with a dispersion method. It is important to consider the liquid influence time specified on the label. If "underexpose", then dirt will remain on wheels. If "overdo", then chemical means can damage a surface. Therefore it is important to wash away its remains a water stream. The remained pollution are removed a sponge or a brush.

On the washed-up disk all winter damages are clearly visible. For example, small scratches at edges of a rim which arose from contact with a sidewalk brow. They can be zapolirovat a small sandpaper or by means of a drill with a grinding nozzle, and then to put with a brush a varnish. Eliminate with the same way small hillocks and swellings on metal. For processing of big surfaces from an aerosol barrel remove a wheel not to splash a brake.

1. Plentifully moisten an aluminum disk with the cleaning liquid from a spray.

2. Leave for some time on rubber – liquid "will eat".

3. Remove a sponge or a rag a layer of dirt and wash out a disk a strong stream of water.

4. Clear a surface a rag.

5. Remove the dirt remains from hard-to-reach spots.

6. Clean a disk a soft brush.

If disks need painting, it is necessary to exempt them from rubber tires, then to do all above-stated operations.

If you want to cover a disk with a protective varnish, remove previously a wheel from the car not to spoil the painted surface of metal details.
