Remove heavy organic soil first.
Spray on, leave for UP TO 5 minutes, work any stubborn areas with a cloth or plastic bristle stiff brush and ALWAYS rinse off with a neutral detergent (dishwash super suds ideal) to neutralize the aluminium cleaner, then a final rinse with clean water.
Do not go in a circular motion with a cloth, as this can cause the aluminum to look uneven in the finished product.
Top tip, a wipe with baby oil when done will leave an amazing finish!!
Always wear suitable PPE when working with Aluminium Cleaner
Try a dilution of 1:30 parts water (+/- 30mls product with 1L water) if you are unsure of the quality of the surface to be cleaned otherwise use neat.
