Method to Clean Patio with Rob Parkers Best Patio Cleaner (removes black spot)

For best results we recommend :

  • Pour product into a bucket. Apply by spreading and brushing with a deck brush.  This ensures true contact with the surface and indentations in the stone.
  • To work effectively the surface needs to remain saturated. Therefore cover the treated area to keep wet, excluding air.
  • Cover treated area with thin plastic and leave for 24 hours.  This will prevent evaporation, and ensure product can really get into the blackspot.
  • Coverage will be approximately 3-5 sq m per litre
  • The black spot will now be dead but still adhered to the treated surface.
  • To remove, rinse off with water using a stiff bristle brush or a power washer to dislodge the dead black spot.
