When using either detergent or cleaning agents always allow time for the product to penetrate the surface that needs cleaning before wiping off or rinsing down. This will produce a cleaner result and effective use of the product on the task you are doing.

Pretesting surfaces
Add a small quantity of detergent to the surface at a dilution to be used for cleaning. Leave for 15 – 30 mins. Wipe from the surface and look carefully for any effect to the surface. If even the slightest effect is observed, do not use the cleaner on that surface.
