Cleaning pumps before storage

[Europhyllia]

I am expecting my new pump(s) next week and want to put my old ones away.
What would be a good way to clean them before storing them.
I thought of just putting them in a bowl with vinegar, plugging them in and just running them in vinegar.
Is that too acidic? Will it corrode things? Should I dilute it?

I did 2 gallon of RO/DI water and 2 cups of vinegar. Then let it air dry before storage.

+1 on soaking in dilluted vinegar solution. That's what we have always done. Not necessary to run them while they soak.

I have done it both ways - running in vinegar and sitting in vinegar. I was told that when storing pumps it is a good idea to take them apart. That way any water or moisture will evaporate out and not sit in the impeller area.

Dilluted vingar works great. I use a cup of vinegar for several gallons of water. Running the pumps is good if you don't feel like scrubbing.

I always use 1/4 vinegar, 3/4 water and run the pumps. you probably don't need to run them but it seems like it makes them come out cleaner.
