text: Well it depends, have you used them in a while? Are they clogged with hair? Your best bet is to get a clipper wash (its really a spray in a can) and hit em with that, following directions. Then if you havent used them in a while you may need a clipper oil (most tack shops have it along with the wash, try statelinetack.com or doversaddlery.com) to get them moving again.
