I use microfibre pads from Solutions along with their Fusion Clean.
This is in a railway maintenance office above New Street station in Brum, and it gets really bad in one end.
There is around 450 sq mts and two of us with 4 pads do it in 4 1/2 to 5 hours.
Equipment needed is a double bucket mop wringer and a larger bucket. I have a plastic box around 2 ft sq. This I have on a flat trolley. One bucket of the double set up has cleaning solution in it. The other is for collecting dirty water.
The floor is presprayed in sections and must not dry out. 15-20 sq mts max at a time.
The first pad is dunked in the solution bucket and very lightly wrung out, then used on the floor. When one side is dirty it is turned over and reused. One pad will do from 5 to 15 sq mts per side.
It is then put in the soak tank of plain water to soak.
When the next pad is needed on the floor the pad that is soaking is well wrung out with the mop wringer on the dirty bucket then dunked in the cleaning solution and lightly wrung out.
The pads in the soak bucket are rotated, the next pad being taken from the bottom.
This method works very well with two rotaries and if there is a third person to prespray and do the pads it is more than twice as quick as two operators.
It does not take long for the soak water to get dirty and need changing. The dirty wrung water is dumped as it is pretty gruesome.
I hope you can follow that lot!! It is easy when you have done it a couple of times.
