I Cannot Remove the Aerator From My Kohler Faucet

If your Kohler faucet aerator is stuck and will not come off, there are a few tricks and techniques to employ before giving up. Removing and replacing the aerator is a smart idea if debris is caught in the aerator or you want to install an on-the-faucet filter. Due to Kohler's unusual aerator design, this chore is harder than it is on other faucets.

Removing Kohler Aerators

Attempt to remove the aerator on your Kohler faucet with your hands. If this does not work, use a rag or another item like a towel to provide more grip to your aerator. Since the aerator on Kohler chrome faucets has a shiny metal exterior, gripping it is difficult. Once additional grip is in place, twist in a counter-clockwise motion with short, hard jerks. This frees the aerator of built-up sediment and eventually loosens it. Grip down toward the end of the aerator, since Kohler spouts overlap the aerators. This provides maximum leverage on the aerator and not the spout itself.

Using Pliers

If using a towel or cloth to grip the aerator does not work, employ the use of vice grip pliers, or regular, adjustable pliers, often called plumber's pliers. These pliers provide an adjustable gripping device with an extension arm to provide leverage. The additional grip and leverage of these devices makes easy work of most Kohler aerators. To avoid scratching the surface of the aerator, wrap electrical tape around the pliers. This prevents damaging scratching to the aerator and spout, since Kohler aerators are mounted at an angle with part of the spout overlapping the edge.

Sediment Removal

If pliers do not work for your aerator, use a sediment dissolving cleaner to loosen the aerator. A cleaner designed to remove lime scale, rust and mineral deposits is useful here. Spray the cleaner around the aerator, near the base of the spout, so it soaks into the threaded portion of the aerator. Allow several minutes for the cleaner to work. Wipe the cleaner off the aerator and try loosening it with your pliers once again.

Leverage

Leverage is important on a Kohler aerator. Remember that the aerator is set at a slight angle to the base of the faucet and the spout. It is, therefore, important to twist the aerator in a rotation parallel to this angle. Otherwise, the aerator will not come off. This is true when using your hands or pliers. Angle the rotation of the pliers by lifting the handle up and pushing the clamp section down while the pliers are facing toward the faucet. Kohler aerators angle downward into the sink basin toward the back of the faucet.
