Quit putting it off & go buy a blower. You need it, and you're not gonna be able to do the things that you really want to get done without it.
Here's what we do when rinsing calves daily:
1. Bring them in and blow them out thoroughly. This removes all the dirt and debris from them before you start rinsing. This does the lion's share of the cleaning.
2. Rinse them really well. I turn on the fans when I'm doing this, and blow 2 sullivan turbo fans right up their tailpipe from this point on. I rinse them and let the fans blow on them until they're cold.
3. I comb them all over with a plastic palm brush, and I work the hair on their legs and tailhead with a rice root brush. If you'll do this one thing every single time you rinse, you'll have trained hair within a week.
4. Blow your calf out thoroughly, being careful to blow the hair the direction that you want the hair to be trained to go.
5. (Turn your fans off) Sheen the calf and blow it in lightly, then blow the calf out again completely.
Every monday I wash with soap, and every Tuesday I treat them with revive very thoroughly. If I find any dandriff spots, I blow some pink oil into those spots when I'm done with everything, and let it stay until I rinse the next morning.
