• Concrete and tile cleaner

Directions
RUST REMOVAL
1. Clean surface of excess rust deposits by wire brushing or chipping.
2. Apply METCLEAN 40 by dipping or painting surfaces to be cleaned.
3. Allow painted surfaces to dry and a smooth grey finish indicates all rust has been converted to a passive phosphate film suitable for application of paint.
4. When dipping components, immersion time is dependent on the degree of rust but with METCLEAN 40 when used in concentrated form METCLEAN 40 immersion times between 30 and 60 minutes should be sufficient to convert all rest to a passive phosphate film.
5. Do not rinse component with fresh water otherwise the passive film will be destroyed and rust will form.

DESCALING OF GLAZED SURFACES
1. Dilute METCLEAN 40 5:1 with water
2. Apply METCLEAN 40 solution to sealed surfaces by painting or wiping
3. Once generation gas from scale has ceased, rinse off with water
4. Do not allow METCLEAN 40 solution to dry on glazed surfaces or allow it to remain in contact with aluminium components more than is necessary to
complete descaling of the glazed surface.

PIPE PICKLING
1. Dilute METCLEAN 40 with water 4:1.
2. Circulate solution through pipework or allow to soak overnight.
3. Drain and allow to dry.
4. Do not wash treated surfaces with water as rust will form.
