Use a clean towel or rag to wipe instruments with a natural cleaning solution. Items are not watertight, so do not immerse in water or place in the dishwasher. Allow to air dry. To disinfect, spray surface with a solution containing ½ teaspoon household bleach to 1 quart water, then immediately wipe dry with a cloth or paper towel. The use of commercial cleaners, chemicals, and solvents should be avoided to prevent compromising the plastic components.
