how to remove calcium build up within bathtub valve body?

After removing the valve in a Kohler Coralais bathtub valve set I tried to remove calcium before putting in a new valve. I tried to stick in a CLR soacked rag with limited success. Is there something like CLR in paste form? Or trade tricks?

I want to clean area where valve meets hot and cold seals.

i've never seen anything like that, I have a faucet where the water flows out through a small troth and calcium builds up, to clean I've had to tie a plastic bag around it to fill with vinegar, a past would be a great way to clean!!

Sounds like the next great "As seen on TV" product!

I've used a brush with muriatic (hydrochloric) acid. Because it's much stronger than CLR it works MUCH faster so you don't have to worry about evaporation.

Make sure you read and follow all the safety precautions if you work with muriatic acid. It is possibly the strongest acid you can readily buy and it is dangerously strong.
