How to clean GHL 2.1 Doser?

[Steve1500]

I need to clean my GHL Doser. I plan to clean the rollers and covers by wiping them down, but how do I clean the pumps? I was thinking about running vinegar through the pumps, thoughts?

The white lines in the pump rollers should be periodically replaced every 12-18 months or so. There is no fluid going through the pumps themselves, you'll see when you get it apart. Basically just replace the lines and clean the rollers and you're good to go.
