Rejuvenate has a fungicidal claim which means it can kill athlete’s foot or other fungal infections and keep them from spreading in foot baths or on other hard surfaces. It cannot be used directly on skin as it is a disinfectant (killing germs on non-living surfaces) and not an antiseptic which kills germs directly found on the body. Look to your doctor or pharmacist for appropriate antiseptics to treat athlete’s foot and other fungi. By the way, did you know that if your client presents with an infection such as athlete’s foot, you have the right to refuse service in the interest of keeping yourself and your spa safe. You may wish to discreetly take them aside and suggest addressing the infection first before proceeding with any treatments.
