General Dirt
Scrubbing with a stiff brush using a mild detergent and hot water is normally sufficient to remove this.
Heavy Staining
Proprietary cleaners are available. Many are acid based and therefore should be used with caution, as they may damage the paving. If they have to be used, test a small area first before an overall application and always follow the manufacturer’s instructions. These can be obtained from Builders Providers.
Oil Stains
Oil penetrates readily into most surfaces and once staining occurs it is difficult to deal with.
Do not wipe as this drives the oil deeper into the surface.
Stains should be removed promptly by soaking up with an absorbent material, eg. a paper towel.
If the stain persists, use a proprietary cleaner in accordance with the manufacturer’s instructions.
Should staining be substantial, it may prove necessary to replace the affected area.
Power Washing
This is not normally recommended, but if it must be used, observe the following:
Remove loose debris.
Test a small area first.
The lance should be held at no more than 30 degree angle and a medium pressure selected.
Any jointing sand which is removed must be replaced.
