To keep your jets performing at the optimum level, it is recommended that you periodically remove them to inspect and clean. A build-up of dirt and sand at the back of the jets will have a detrimental effect on their performance and life. Simply by turning your jets firmly to the left, you can remove the jet assembly from the housing. Gently tap the jets on a hard surface to loosen any debris and soak in a bucket of warm water. Refit jets to the body housing.
