Clipper blades last longer and work more efficiently if you keep them clean. Cleaning is also necessary to prevent spreading fungus (such as ringworm), germs or parasites (such as lice) during dog grooming. You should clean your clipper blades after each use. It doesn't take long, especially as you won't have to deal with a build-up of pet hair, dirt or rust on the clipper blades if you do clean the blades every time.
Brush off excess debris from the blades with an old toothbrush. Pour an antibacterial clipper blade wash into a shallow pan. There are many brands of these washes and you can find them easily at most places that sell pet grooming supplies.
Submerge the blades, still intact on the clipper, into the cleaning solution and turn the clipper on for few seconds. Turn it off and then on again. You should see some hair and dirt come out into the pan. Do not submerge any other part of the clipper except the blades.
Wipe the blades with a soft cloth. If you notice any remaining dirt, submerse the blades again in the cleaning fluid, with the clipper running.
Remove blades and wipe with a soft cloth, and then let them air dry on a towel or soft cloth before oiling. You should always oil the blades with clipper oil before returning the clipper to storage or using it.
Always keep the blades pointed down while cleaning to avoid getting moisture in the clipper's motor.
The manufacturer of your clippers may recommend a specific product for cleaning your clippers. Using other products may void the clipper's warranty. Always follow the manufacturer's advice for best results. Only use clipper blade oil on clippers and follow the manufacturer's instructions. This prevents rust, prolonging the life of the clipper. You can find clipper blade oil most places clippers are sold.
