Just so you know we don’t just clean stone and tile floors we also do external patios as well and this particular job was at a property in Cambridge with a Sandstone patio. We have all the tools and products to clean most surfaces so cleaning patios and brick paved driveways isn’t a problem.

The process was quite straight forward and involved pre-soaking the driveway with Tile Doctor Pro-Clean, it’s a versatile cleaner that equally effective on Patios as well as Tile, Grout and Stone; being an alkaline cleaner it has the added advantage that it doesn’t cause damage to the surface that typical acid cleaners can.

The Pro-Clean was left to dwell on the patio for a good hour before scrubbing it in with a stiff brush and following up with a high pressure professional jet washing machine which did a great job dislodging the grime that had built up on the surface over time. You can see from the photographs what a difference it made.

Pressure washing can dislodge the grout joints so once we were done cleaning the floor the gaps between the tiles was filled in kiln dried sand.
