Cleaning ovens, grills and cooking plates: ensure that the surface to be cleaned is not hotter than 80°C (ideally 50-60°C). Apply neat product to the surface and leave to work for a few minutes. Remove any residue with an abrasive sponge or brush. Rinse thoroughly with water. Cleaning fryers: drain off the oil and close the valve. Fill the vat with water to the level of the oil. Add 50-100 ml of product per litre of water (5-10 caps per 10 litres). Switch on the fryer and bring the solution up to boiling point, without exceeding 100°C. Cool and empty the vat then remove any residue with an abrasive sponge or brush. Rinse thoroughly with water. Cleaning cooker hoods: prepare a solution with 50-100 ml of product per litre of water. Use hot water for better results. Leave the disassembled cooker hood components in soak for 5-30 minutes. Rinse thoroughly with water.
