Santizing Test Roll Quat Test qt-10-1

Started using Quat tab since COVD-19 (1 tab to 1 gallon of water with spray bottles). Read somewhere cotton cloth is no good because cotton binds to the ions rendering Quat tab ineffective. Decided to experiment. From the picture there are 6 test strips. Starting at extreme right, solid green was from a freshly made Quat tab batch in one gallon of water. To the left a lighter shade of green tested immediately after dropping cotton towel. To the left of that the almost yellow looking strip was tested about 1 minute after towel was in bucket.200 PPM is acceptable according to health codes so the yellow strip still passes but I prefer my batch to be stronger at 400 PPM so want to see more green color.Three test strips on the left side of picture all show solid green. They are tested the same way except micro fiber cloth was used instead of cotton. It shows micro fiber does not reacts with Quat tab. Research I read said the same and recommended micro fiber cloth instead of cotton.

I got this to test hypochlorite acid solution but once the paper touch the solution become decolonized pale yello not exactly a reading

Oops. Bought this instead of chlorine testing strips for hypochlorous water testing for sanitation. I'll see if this can find a purpose.

This works great if people remember to use them. It's great to do training, then have the health department show up and ask how they work and no one has a clue. Demoted a manager because he could not demonstrate it properly.

The product does not work, it's the same with water as with vinegar.Im sad.
