Thanks for letting us know your experience with hot water. The chemist who designed the strips even provided us with instructions on what to expect when using hot water with quats.

Excellent product- temperature range is far more liberal and fits our needs. State surveyor recommended! Down side is cost may be a factor considering old strips are provided for free from our vendor.

— Indigo:

If you are using old strips, be careful as they may not be accurate. We in fact guarantee ours for 3 years minimum.
