These effervescent windshield wiper tablets transform regular water into a powerful, eco-friendly glass cleaner. Just drop one 10 g tablet into the wiper fluid reservoir (up to 4 L), and let it dissolve—no more bulky cans or pre-mixed solutions. Removes stubborn contaminants like bug splatter, bird droppings, road grime, tree sap, oil film, fingerprints, and soot for spotless, clarity-enhanced windshields. One tablet in 4 L of water yields ready-to-use washer fluid, saving storage space and creating less mess than conventional cleaners. Formulated with lubricants that reduce friction, soothe rubber wiper blades, and prolong their lifespan while reducing noise. Biodegradable, phosphate- and ammonia-free, non-flammable, and fragrance-free—safe for glass, metal, rubber, plastic, and painted surfaces. As small effervescent tablets (≈1.5 cm diameter), they compactly store in a box, are easy to transport, and preserve potency when sealed.
