Cleaning without an Ultrasonic

•Dab off dirt etc. with a cloth, clean brush or cleaning putty. Further clean with a damp towel (Simple Green or Orange Clean)
•If using a foaming spray cleaner…it will migrate into the bearing. If liquid, a heavy spray, or sitting them in a jar will help get the solution in. Blow out lightly if possible or dry on a towel.

•Turn gently to check if clean. Repeat if necessary.

•If clean, oil and re-install.
