Apply BIOTENSIDON'S Metal-Cleaner mixture (depending on the pollution you can make a mixture with the ratio up to 1:3) on the surface according to the contamination. 

Processing temperature mustn’t be less than 1°C. Spray on the surface and scrub with a plastic brush (not with a sponge because it absorbs too much of the product) Rinse with clean water.

All general waste disposal requirements are met; there are no additional requirements to be observed.

The concentrate must be mixed with water, needs oxygen and more than 1°C for perfect results. It should be pointed out, that if the concentrate is diluted with normal tap water, the Metal-Cleaner mixture may change its properties (substance and cleaning effect) after 2 to 4 weeks.

To avoid that (in case the storage of the product is for a longer period than 4 weeks) it is necessary to use purified water instead.
