A highly concentrated, powerful and readily biodegradable heavy duty solvent degreaser. Sobo Tank Cleaner penetrates and lifts the heaviest of oil contamination with reduced risks for the environment.

The new Sobo Tank Cleaner is a rapid and effective cleaner for waxy and residual hydrocarbons from storage tanks walls and floors. It is effective against asphaltine, crude oils, tars, hardened greases and heavy soils.

This ultimate readily biodegradable cleaner is more environmentally friendly than many other commercially available products. Free from harmful volatile organic compounds (VOCs) and non-flammable, Sobo Tank Cleaner is not only cost effective but safer for the environment and the user.

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 water.
  • Fill the pressure washer tanker with water.


  • Pour the required amount of Sobo Tank Cleaner into the pressure washer water tank.


  • 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.
  • For best results, use hot water.


  • 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.
