Where to Use

Oil storage tanks require periodic cleaning for a variety of reasons, for example to maximize available storage capacity, to make repairs or to reconfigure.

Sobo Tank Cleaner is specially designed to remove waxy and residual hydrocarbons from storage tanks walls and floors.

Can also be used throughout the oil & gas industry to remove heavy contamination from surfaces, including contamination from asphaltine, crude oils, tars, hardened greases, hardened oxidised oil and heavy soils. 

  • Please note: Sobo Tank Cleaner is not registered for offshore use.

How to Use

Sobo Tank Cleaner must be diluted with water in order to activate it - do not use neat.


  • Agitate to activate the emulsion and then dilute to required concentration.
  • Dilution rate is 4-10%, ie 40ml to 100ml of Sobo Tank Cleaner per 1 litre of solution.
  • Fill the pressure washer tanker with water.
  • For best results, use hot water.


  • Pour the required amount of Sobo Tank Cleaner into the pressure washer water tank.
  • To use at a 4% solution, use 40ml of Sobo Tank Cleaner to 960ml of water; for a 10% solution, use 100ml Sobo Tank Cleaner to 900ml water.


  • Begin applying the solution to the oil contaminated area, starting at the highest point.
  • Diluted solution that flows down the tank wall will act as a pre-soak for the lower, fouled surfaces.


  • Allow a contact time of 10-15 minutes before rinsing with water.
  • Allow up to 60 minutes when used in the cleaning of oil tanks or heater tubes
  • For best results, use hot water to rinse after use.
