This was a very colourful floor after we had cleaned it, as you can see, it wasn’t before! For cleaning this Limestone floor in Lancashire we mopped a solution of heavy duty floor cleaner and stripper on to the floor and allowed it to work in for 10-15 mins to loosen the old sealers and soiling etc, gave it a good clean with a heavy rotary machine with a medium to stiff floor scrubbing brush, hand cleaned the grout lines, edges and corners, thoroughly rinsed the floor with fresh water after extracting the slurry, allowed it to dry and applied a sealer, protector to leave a lovely Satin finish.
