I am pleased to provide this reference in relation to our program’s use of the Protocol K-650. We are excited about using a product that is not only environmentally safe to use, but that is also incredibly effective. Our cleaning staff also find easy to use. In fact, of all similar products that we have trialed over the years, we have found this to be the most effective calcium, lime and rust remover we’ve seen. It is also easy to clean up-no sticky gel. It goes on like water and instantly removes build-up. We have also found it very effective at removing stains that we have not been able to successfully remove with other products-such as on flooring and stainless steel, and grime/build-up in floor sinks that we thought were stained beyond repair. It’s surprisingly gentle on surfaces that tend to be quite sensitive to such products.
