1. Remove the wheels from the skates and take the bearings out of the wheels.

2. Remove at least one shield from bearings. Use something sharp to do this like a needle or a pushpin.

3. place bearings and other parts in wash container. a bowl or cup is a cheap alternative.
We recommend:
- Powerslide Turbo Wash
- Bones Bearing cleaning unit

4. Add a special cleaning liqued. Soak for a few minutes and swish lightly. Brush slightly with old tootbrush and soak them again for a few minutes. The cleaning liqued can be used 3 or 4 times. just pore it back in to the bottle after you are done.
We recommend:
- Powerslide Citrus Cleaner

5. Remove bearings and allow bearings to dry before lubricating.

6. Grease the bearings with bearing oil or grease. Grease stays in the bearing longer and oil lets you go faster.
We recommend:
