The spray works perfectly with my swimming goggles. I swim a week three to four hours in chlorinated indoor pools and have previously always had the problem that even very high-quality glasses have lost after about a month their anti-fog capabilities (anti-fog and hydrogen chloride may be not fact). This budget Spray has long been retrieved long-lost favorite swimming goggles back to life: Simply the glasses lightly spray the inside, leave on for 10 minutes, rinse with cold water ready. The glasses no longer steam up and you finally "include tiles" correctly clear view while.
I would recommend this product to any and will buy it there again.
