All StoneClean Concentrates are exceptional and grabbing the dirt and grime and then floating it to the top to be mopped away.
My first time using StoneClean 104 was deep cleaning a Saltillo tile floor that had not seen a mop and bucket for years. I was shocked to see how where I mopped the floor came clean where I rinsed.
The homeowner was shocked as well and then ordered six gallons. They probably still have product left!
One homeowner in Kansas City commented that her grout was coming cleaner with each cleaning without scrubbing. The surfactant based cleaning chemistry puts the cleaning solution into full contact with the floor allowing it to work deeply better than any other product I am aware of today.
I will comment on StoneClean & Strip tomorrow.
