How to clean a pump impeller

[ari5736]

My Blueline impeller is all cruded up. Do I soak in vinegar or acid? What type? What do I use to scrape with?

Soak it in distilled vinegar for a few hours and the take an old tooth brush to it. The longer you let it sit in the vinegar, the easier the crud will come off.

You could also just let it run in a bucket of vinegar water for a couple hours. Might be less work.
