CHLOR-KLEEN EXTRA is suitable for use as Farmyard Cleaning Chemicals on Concrete, Patios and for General Cleaning. Due to the broad variation of patio slabs and other paving materials, a small area should be tested first for suitability as colour variations may result.

CHLOR-KLEEN EXTRA concentrate or solutions should not be sprayed on herbage as may cause damage or burning.

Use Instructions

Please check the label for all usage information

Apply a 20/1 dilution of CHLOR-KLEEN EXTRA (1 part CHLOR-KLEEN EXTRA to 19 parts Water) by brushing or spraying.

Spread evenly over the surface.

Leave in contact for 15 to 30 minutes before washing off with a large volume of water.

Additional Information

CHLOR-KLEEN EXTRA is most effective for cleaning concrete type materials and is not recommended for tarmac cleaning. Short term contact on tarmac surfaces is acceptable provided the contact time is short and the CHLOR-KLEEN EXTRA solution is rinsed completely with a large volume of water.

To maintain your surfaces algae free for an extended period ROCKQUAT KG should be applied when the cleaned surface has dried at a rate of 1 part ROCKQUAT KG to 100 parts water and repeated every three months for best results particularly if the surface is shaded from direct sunlight.
