PT RC Racing Gear Diff Cleaner is a silicone based cleaner that works by diluting the diff oil that it is to be removed from the differential. Since it is silicone based it will not contaminate the differential with other chemicals that may harm the seals or contaminate the new diff oil.


(1) Open the differential, removed as much oil as possible but leave all the gears inside.

(2) Pour Diff Clean in the differential and temporarily close the differential.

(3) Agitate the oil by spinning the gears in the differential 10-15 seconds to dilute the diff oil.

(4) Open the differential, pour out the diluted oil, a microfiber towel may be used to clean the differential.

(5) Repeat steps 2 thru 4 approximately 3 times as required to completely dilute and clean the differential and gears. May require additional times if the oil is of very heavy viscosity. (If available low pressure or canned compressed air works well by blowing air into the differential housing with the cross shafts and satellite gears removed. Always exercise caution when using this method, always direct spray away from you and/or cover diff with a cloth.

(6) Lastly do a final wipe down of the diff housing, diff cap, cross shafts and satellite gears. For best results discard the gear diff cover gasket and replace with a new gasket every diff rebuild. (if applicable) The result is a differential assembly that is completely clean without the use of any hard solvents. Using Diff Clean allows for a consistent operation of the differential. Diff oil viscosity changes are consistent and accurate due to the differential not containing any residues of old oil or harmful solvents.
