Needed a line brush to ensure line cleanliness before and after each brew session. This tool makes it possible to clean approx. 4' of hose in a quick second. I wish this had been included with my first brew kit. Cleanliness is next to Godliness and this product almost makes you a monk.
These brushes are the best way (only way?) to scrub inside your tubing. Running water and cleaner through the tubing is not going to ensure that all the built-up scale and residue will be removed. Your tubes may LOOK clean, but there is still plenty of invisible stuff going on in there. Unless you scrub it all out with one of these brushes!
How else do you get those lines clean? You need a brush! It's long and flexible, gets all the little solids dislodged. Can be a little funny to store because the handle is so long but that's the nature of a long brush.
