It does what it promises. It is not a strong chemical, so there is no risk of damage. With the help of a brush, the wheels shine.

It is perfect until the last drop.

The custom wheel cleaner is one of the three wheel cleaners from AutoGlym. This one is the mildest and suitable for all types of wheels, including plain aluminum, chrome, lacquered, anodized, and even plastic (if a wheel has a cap or something similar), without causing any damage to the brake pads.

For use, it is simple (on cold wheels):
- Wet the wheels.
- Shake the bottle.
- Spray the wheels one by one, covering them. It is not necessary to soak them. I usually spray four to five times from about 20cm away in a star-shaped pattern.
- Wait for 1 minute for it to take effect. (You will see the dust from the brakes running off.)
- Clean the wheel with a sponge as thoroughly as you want.
- Rinse with water and you're done.

Now, as I mentioned earlier, this is one of the three cleaners, the mildest one. For this reason, you may need a second round to properly clean the wheel. I get about 12 washes per bottle, depending on how much time passes and how dirty the wheels get from the brakes. (One wash includes all four wheels.)
