Cleaning the lines of your tap is a necessary and valuable thing to do if you want that perfect pour every time, but many beer line cleaning chemicals are harsh and can be fatal if swallowed. It is important to rinse your lines thoroughly after every cleaning to make sure there are no leftover chemicals in your lines that may transfer to your beer.
This is why this specially designed pH Testing Paper will allow you to check the pH level of the rinse water. Keep it between 7.0-8.0 and you’re in the green. This litmus paper product changes color to indicate pH levels.
