Where to Use 

  • An effective, aqueous, alkaline degreaser, designed for use Offshore
  • Ideal for degreasing pipework
  • Also suitable for passivating mild steel after acid pickling and scale removing operations (ideal for use in conjunction with Sobo Scale)


How to Use

  • For heavy duty degreasing:

    • Use as supplied
  • For general purpose cleaning:

    • Use at a dilution of 1 part Sobo GR to 19 parts water
    • The use of warm water is recommended, ideally at approximately 60°C
    • Dilutions with fresh water can be stored for use later
    • Dilutions with sea water should be used immediately


  • Can be used with care on aluminium, zinc and magnesium alloys.

The Offshore Chemical Notification Scheme (OCNS) manages chemical use and discharge by the UK and Netherlands offshore petroleum industries and applies to all chemicals which are used in exploration, exploitation and offshore processing on the UK Continental Shelf.

The scheme applies to those “operational” chemicals and products which through their mode of use are expected in some proportion to be discharged, eg. rigwashes and hydraulic fluids.

As part of the OCNS, every three years the hazard assessment of chemical products that are used offshore need to be re-assessed by the Centre for Environment Fisheries & Aquaculture Science (CEFAS).

CEFAS applies a Chemical Hazard & Risk Management (CHARM) model to calculate the ratio of ‘Predicted Effect Concentration’ against ‘No Effect Concentration’.  This allows the product to be ranked in the form of a Hazard Quotient.  Part of this assessment includes toxicity, biodegradation and bioaccumulation.  To allow users to very quickly understand the hazard quotient of a product, CEFAS in the UK use a colour branding system, as follows:

CEFAS table SoboGR

  As you will see, Sobo GR has been classified by CEFAS as GOLD meaning that it has the lowest possible Hazard Quotient available!
