1. Turns regular water into powerful cleaning fluid, one tablet in 4L water will equal to 4L windshield washer.2. More conveniently and easily to use than traditional windscreen cleaner.3. Environmental friendly, biodegradable, phosphate and fragrance free formula.4. How to use- just open glass bottle cover, find the wiper tank, fill it with water and put into a grain of block concentrated. At last, wait for 6 minutes and then use it normally. You may wait for more 5 to 6 minutes in winter.
