Qwix Mix Windshield Washer Fluid Concentrate

No. The concentrate is a surfactant-in-water formula with no freeze agent. It provides protection only down to +32°F (the standard freezing point of water). For cold-weather use, the label mixing chart specifies the percentage of alcohol to add for protection down to −25°F — that ingredient must be purchased separately. The product is ideal for warm-weather or fleet use where a freeze agent is already on-site.

Approximately 7.6 mL (about 0.26 oz) per gallon, based on the label mixing chart. One 1-gallon jug yields up to 500 gallons of working fluid when mixed with water. For freeze protection, the chart also specifies the alcohol percentage to add at each target temperature — from 7% (for +20°F protection) to 35% (for −25°F protection).

The manufacturer markets the product as '100% Biodegradable' and the formula is a proprietary surfactant in water. The SDS Section 12 states persistence and degradability as 'Not determined' — independent analytical confirmation is not in the SDS documentation. The biodegradable claim is manufacturer-attributed and has not been validated by EPA Safer Choice or an equivalent independent certification.

The product is marketed for cars, trucks, and fleets. As an alcohol-free, surfactant-based formula it is unlikely to harm rubber hoses, reservoir plastics, or wiper blades — issues sometimes associated with high-alcohol formulas. Users who add a freeze agent per the label chart should ensure the ratio does not exceed the recommendations for their vehicle's washer system.

The concentrate itself contains no alcohol — the SDS §3 lists only a proprietary surfactant at 1–5% in water. However, the label explicitly instructs users to add a freeze agent separately for any freeze protection below +32°F. If you use this product in winter conditions and add that ingredient yourself, review its SDS before handling.
