Beer Cleaning Kit for my System

[c59]

I have a single kegerator with 3 perlick faucets that I would like to clean every month.

Interested in the pressurized cleaning system, but I don't know what size to get 1.3gallon or 3.9gallon? Also, the cleaning solution required asks for 1/2oz. of powder per quart of water. 1.3gallon kit requires 2.6oz. and 3.9gallon kit requires 5.2oz. Seems like I'll go through this powder really quick. Maybe I need to understand how many quarts is required to clean the 3 kegerator lines. Any thoughts?
regards,
Vince

I have the 1.3 gallon and it does not need filled all the way to clean your kegerator lines. I fill mine about half way to clean my three taps and that is more than I find I need typically.

Agree with Psychodad.
