Anti-fogging spray for visor and cross-eyed glasses Muc-Off Anti Fog is a deworming spray made with a groundbreaking, environmentally friendly and moisture-absorbing formula. The spray puts a microfine and transparent film on the MX glasses or the visor of the helmet, thereby preventing misting for up to 5 days. Sprayed Muc-Off Anti Fog on the outside of the spectacle lens or visor also has a repellent effect on rain. The spray is biodegradable and can therefore be used with a clear conscience. For good visibility while driving If you often experience dew on the inside of your helmet or cross-eyeglasses, Muc-Off Anti Fog is an obvious choice for you. The spray effectively inhibits the formation of dew, so you do not have to worry about disturbed visibility on the scooter or motocrosser. Be sure to use only Anti Fog from Muc-Off on a completely clean and dry surface. Shake the spray and then spray a light but even layer on the surface. Wipe dry with a dry cloth.
