Cleaning climbing holds?

I recently bought some used climbing holds that are very slick because of the chalk/sweat cake covering each hold.

What is the best way to remove it and get some of the texture back?

PS -- I have already tried the dishwasher without much success

As Will said vinegar works great. I use a 3:1 ratio, soak the holds for about 10 minutes, scrub with a nylon brush and rinse (no pressure hose for me).

We used to run all the holds through a dishwasher with dish detergent at the old gym. It work pretty well. Sometimes, you'd get a little residual grime, but it comes off with a brush.

If you are looking for a no scrubbing way, its a good option

Hey Brett,

Have tried muriatic acid yet?

works pretty well for getting the crap off without messing up the texture. Just be REAL careful with the stuff!

Alcohol works well.
