TL;DR Summer-only concentrate that mixes 1:100 with tap water · the best effective-dilution economy in the category. Community reviews consistently confirm strong bug and road-film removal with a streak-free finish. Health score 6.2/10 · WARNING-class formula with skin and eye irritation hazards at concentrate strength; the working solution falls well below the irritation threshold.
A summer cleaning concentrate with zero freeze protection · the working solution freezes at 32°F. The built-in squeeze mechanism fills a 2.5ml chamber per dose; at 1:100 dilution the 250ml bottle makes approximately 6 gallons. Community reviews rate bug and road-film removal above average for this category, with multiple owners confirming heavy accumulation clears in a single wiper pass. Streak-free clarity is consistently mentioned across the review set. The formula is phosphate-free and confirmed compatible with PPF, ceramic coatings, and Rain-X additives.
Best for owners in mild or warm climates, or anyone who already runs a separate winter formula. The 1:100 ratio delivers strong per-gallon economics for drivers who top off frequently. Skip it for northern-climate year-round use · the working solution has no sub-freezing protection.
SDS §2: WARNING signal word from H315 (skin irritation) and H319 (serious eye irritation) at concentrate strength · both fall below threshold at 1:100 working dilution. Eye protection is the H319-based SDS precaution during concentrate handling; skin protection for direct concentrate contact. Confirmed biodegradable per EU Detergent Regulation; working-solution VOC is negligible. The preservative carries ingredient-level aquatic toxicity · product reaches stormwater via windshield runoff; avoid storm-drain disposal of unused concentrate.
No. This is a summer-only cleaning concentrate. Once diluted 1:100 with water, the working solution has no antifreeze component and freezes at approximately 32°F (0°C). For sub-freezing temperatures, use a separate winter washer fluid or a multi-season formula rated to your local low temperature.
The 250ml bottle has a built-in measuring squeeze mechanism. Squeeze the bottle to fill the 2.5ml measuring chamber, pour into your washer reservoir, then top with water. The 1:100 dilution yields approximately 25 liters (6.6 gallons) per bottle · about 100 reservoir fills.
Owners confirm compatibility with PPF, ceramic coatings, and Rain-X additive blends, with community reports of a streak-free, hydrophobic result when mixed with Rain-X at label ratios.
The WARNING designation reflects the SDS §2 classification of the undiluted concentrate: H315 (skin irritation) and H319 (serious eye irritation). Both classifications are for the concentrate at bottle strength. At the 1:100 working dilution, the active concentrations fall below the irritation classification thresholds for normal use.
