Product Details



SP10 is a very powerful caustic detergent. It can be used neat to remove high concentrations of grease or carbon stains. In addition, as it’s a super-strength solution, it can be diluted with water (see below). SP10 contains an anti-rust additive to prevent flash rusting on clean steel.

  • SP10 will remove grease, dirt and carbonised grime.
  • Can be diluted in a 1:4 ratio for general cleaning (1 part SP10 with 4 parts freshwater).
  • Can be diluted up to 1:100 when used neat in a power wash ratio dispenser. Pour neat SP10 into the detergent tank and set the dial to 1:100.
  • When applying by brush, allow SP10 to foam on scrubbing as this will allow the SP10 to emulsify the grease and dirt. When clean, wash all SP10 residue away with fresh water or Rustbuster Chlor-X Salt Remover.

Substrates/items SP10 can be used on: steel, engines, farm equipment and plant, concrete floors, tiles, plastic and GRP. (Do not use on painted surfaces.)


Do not use SP10 on paintwork as caustic staining may occur.

Do not allow SP10 to dry on aluminium as white staining may occur.



Product description A yellow coloured liquid for the removal of grease.
Directions for use Apply neat or diluted 1:4 by brush or spray to the surface, working into the substrate with a brush to create a foam on the surface. Leave between 5-60 minutes to allow the product to work. Wash away the SP10 with fresh water or Rustbuster Chlor-X and allow it to dry.
Cleaning Brushes and equipment used can be washed clean in fresh water.
Safety Wear suitable protective clothing, gloves, apron, mask, eye and face protection.
