Follow the dilution instructions on the bottle. Just dilute it with water.

The Aircraft Cleaner is less corrosive than the 'standard' formula and is safe on most rubbers and plastics. I've cooked carburetors (with rubber, plastic, and brass parts still installed) for 2 hours in my ultrasonic cleaner with this stuff with no ill effects.
