Cleaning question

[d-maz]

Hey Roger, what's the best way to clean the hole where my 6105s impeller goes? There is some caked stuff on the sides down toward the bottom.

Thanks, Dave

I pour vinegar in it and let it sit, when it stops foaming I rinse it in warm water and repeat until it is all gone. A 1/4" diameter nylon brush can help loosen it and it may well take some hours if it is really caked on and a few fills.
