Hi, this is a FYI fo...
It's ok to clip them dry and dirty. I do it too, sometimes. Its recommended to clip them clean. The life of your clippers will be longer if you bathe the animal first. When you don't bathe them first, the clippers will get duller faster and heat up quicker. Just remember to change the blades a little more often and clean and oil them. I usually clean my blades with blade wash then oil them when I'm finished, and I clean the clippers and oil them also.
