The paper cleaning method for cleaning yoyo bearings.

Learn to clean a yoyo bearing with lighter fluid and then get it extra clean with the paper cleaning method.
What you need: A glass dish, a solvent (we use lighter fluid), a pin, the bearing you wish to clean, a pencil, a piece of paper towel, a piece of paper, scissors.
Step 1: Remove the bearing shields. Press the pin into the c-clip on the bearing to remove it. Once the c-clip is removed the shields will fall off. (After cleaning, the shields do not need to be put back on the bearing.)
Step 2: Put the bearing into the glass dish and put in enough solvent to cover the bearing.
Step 3: Give the glass container a little shake to move the solvent around, then wait five to fifteen minutes.
Step 4: Remove the bearing from the solvent (you can use the pencil), and let it sit to dry on the paper towel for about 10 minutes.
Step 5: Once the bearing is dry, put the bearing on the tip of the pencil and spin it with your finger. If the spin is smooth, pat yourself on the back, you're finished! If not, repeat all the prior steps. If the bearing still does not spin smooth proceed to step 6.
Step 6: Cut off the corner of the piece of paper to make a triangle about 1.5" long and 3/4" wide. Fold the paper in half.
Step 7: With your bearing on the end of the pencil, thread the thin end of the paper between the balls of the bearing while touching the outer race of the bearing. The paper should poke through to the other side.
Step 8: Pinch the bearing and rotate the pencil 10-20 times.
Step 9: Remove paper and check for black on the edges.
Step 10: Repeat steps 6-9 until no black gunk appears on the paper.
Step 11: Once the bearing is spinning well, lube the bearing with thin yoyo lube.
Step 12: Rejoice, you are done!
