La Tromba AG In Clean

I have used this cleaning fluid for my tubas. Very large and heavy instruments, so internal cleaning can be difficult. After some trial and error, I found the best way to use it was to mix this cleaner with water (in the correct proportion) and then place that mix into a spray bottle. I then spray the mix inside my tuba. Wait a few minutes. Do it again. Wait, agin. Then flush out the tuba's pipework with fresh running water. Works very well and no having to lift a heavy tuba around during cleaning.

This fluid has good smell and is not too harsh to the hands. Not sure about "protection" efficiency but it seems to be gently cleaning.

This is a great product from the brand (Tromba), you don't need to use much to leave your instrument very clean, I recommend it!!!
