WristClean manufactures its own formulas in-house and controls every ingredient. We also bottle and label our own products. We fully own the quality of our products from start to finish. Our proprietary formulations include our 'Microsuds Technology' to mitigate scratches and provide a gentler cleaning for waterproof gaskets. This is unlike many watch cleaners that are re-labeled jewelry cleaner or generic cleaners from overseas. They are simply not formulated properly for watches. You can feel & see the difference when using our cleaner. Your watch will feel silkier and look its best (like new).
