Salt mixture residue removal?

[Reef Reaper]

I use Reef Crystals for my tanks. The tanks are fine but the residue in the mixing container. I was wondering if there was a quick method of removing the residue from the mixing pumps? The salt is great but maybe it is time for a different, less messy salt. Any suggestions, i know this is an old question that has been asked many times. Thanks for looking

Try some citric acid and water. Should take it right off.

I tried the citric acid and water but it was still stuck on but thanks for the info.

Hmm. It usually works for me. I do over mix it though. Use a lot more than needed.
