Ensure that internal wing-tip cap has been placed on canister.

Hold canister in an upright position and shake vigorously for 20-30 seconds.

Withdraw the plunger slowly until it stops at the catch line. This is the dotted line near the top of the applicator barrel. It is not the fill line.

Hold applicator by barrel. With canister sitting on counter top, place applicator tip over wing-tip cap and push down gently so that applicator is firmly attached.

Push down a number of times on the wings of the internal cap. Each press releases a small amount of foam. When the applicator is half full of foam, stop for a few seconds until the foam stops expanding. Press down again to complete filling to the fill line.

Remove applicator from canister, leaving some foam on applicator tip. Hold applicator by barrel and gently insert applicator tip into the anus and then push plunger to release foam and complete treatment.

To clean, pull applicator and plunger apart and wash with warm tap water.
