Cleansing Patios and Paths
The process I follow for cleaning paths, patios and paving generally is basically to apply a strong dilution of Tile Doctor Pro-Clean and then let it seep in to get to work on the dirt and grime for about ten minutes before scrubbing with a stiff brush; this is then followed by pressure washing.
Home owners can buy pressure washing machines and many domestic models are available in DIY stores nationwide, however none are as powerful as the machines used by Tile Doctors which can generates pressures far in excess of a domestic system that make light work of cutting through grime.
