This floor was in a former gas station grocery store.
It was a variety of soils and when first looked at it was suspecting possible topical but turned out just heavy type soil that would cling to even the ceramic tile
We tested variety of products as you might see in the pic and variety of tools.
For this floor, the heavier weight of the RX 20 with an aggressive tile and grout brush was best for agitation...
For chems... We did find one that worked better and stuck with it. We also went back over all the other areas we had tested with other products to make sure would match.
The Rotovac 360 XL tile head is pretty awesome but it won't necessarily replace the good old TH 40 hydroforce turbo....
For grout line we were finding the interlink Stainless steel grout brush was best there but also used one of the shark brushes for edges... But the rotary with aggressive brush really helped.
No sealing wanted after, just clean it up.
Overall, I just think a person needs to be prepared for the unusual on these jobs but we did make nice time and pretty good pay...
New guy doing great by the way... His feet never stop moving... Good kid
