Unger, The Pill Glass Cleaner, 500 Tablets/Bottle

The Pill Glass Cleaner is a pre-measured and individually packaged soap that takes the guesswork out of measuring. Mix one pill with 2-1/2 gallons of water. The Pill is biodegradable, skin friendly, and non-toxic. In the event of cold weather conditions, the window washing solution may freeze. To prevent the solution from freezing we recommend making a 50/50 solution of windshield washing solution and alcohol.
