Method of use

Prepare a 2% to 5% solution of Decon 90 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 (40°C to 50°C) 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.

* Ready Biodegradability by OECD 301E (ISO method 7827 - 1986 (E))
** Decon 90 satisfies the criteria in BS EN 1040 1997 for bacterial activity.
 For critical applications, use demineralised water throughout.
