From the description:
Just pour in a 2:1 ratio (water:concentrate), or stronger if desired, in your washer fluid reservoir. When it sprays on your glass it quickly melts the ice and stops ice from forming again so you can drive safely and with confidence. It also does a great job of cleaning your glass leaving no streaks behind so you see clearly and easily through the glass. The formula will not fade or otherwise ruin your surrounding rubber, plastic, vinyl and painted surfaces. Traditional washer fluids often use methanol and or ammonia which can dry out and fade some trim pieces. Instead of harsh chemicals this formula uses pure nature alcohols and it's 100% bio-degradable, so it's environmentally friendly. It even smells pleasant with a citrus based scent.
