Method of Use

Prepare a 2% to 5% solution of Contrad 2000 with water†

Fully immerse the items to be cleaned and soak for 2 to 24 hours, depending upon the degree and tenacity of the soiling.

Problem contaminants can be treated by increasing the solution strength.

Cleaning time can be reduced by heating the solution (40C to 50C) or using in an ultrasonic cleaning bath.

The cleaned items must be rinsed thoroughly as soon as they are removed from the cleaning solution, and dried. We recommend three agitated rinses in water† to ensure removal of all traces of contamination and cleaning agent.
