Product description

Streaky wipers, a hazy windshield in the rain, glare from oncoming headlights at night—a lot of people just give up and top off with tap water. This windshield washer concentrate has a neutral formula and is simple to use: pour the whole bottle into your washer fluid tank, fill the rest with water, then use your wipers and washer spray as usual. No dwell time and no extra wiping needed. One car uses about 20ml. Besides car glass, it also works on glass and tile at home. If your car has a glass ceramic-type coating, be sure to read the cautions below first.

Fill the rest of the tank with water.
Then use your wipers and washer spray as usual. No dwell time and no extra wiping needed.

Things to know

Do not use this on a vehicle with a glass ceramic-type coating (glass coating). For a coated vehicle, use deionized or purified water in the washer tank instead—washer fluid with strong cleaning additives like oil-film removers or anti-freeze agents can affect the coating layer.
We don't have tested pH data or a safety data sheet for this product yet, and we make no guarantee about its acidity or alkalinity.
Washer fluid tank capacity varies by car (roughly 2 to 5 liters), so the actual concentration after pouring in the whole bottle will vary.
Always follow the dilution ratio on the label. If it's not labeled or you're not sure, message us on WhatsApp before using it.
We don't have compatibility data for mixing yet, so don't mix it with other washer fluids or additives.
Keep out of reach of children and avoid eye contact. If contact occurs, flush thoroughly with water.

FAQ

In Taiwan's lowlands, winter usually doesn't need anti-freeze, but high-altitude areas (Hehuanshan, Alishan) or places with strong winter monsoon winds should still use an anti-freeze formula. In summer, a higher dilution ratio lowers the anti-freeze concentration.

Yes. Glass coating makes rain bead up and roll off, while the washer concentrate lets your wipers clear water without streaking—the two work together. We recommend applying the glass coating first, then topping up with the washer concentrate, for the best visibility when driving in rain.

For summer in Taiwan's lowlands, we recommend 1:20–30. For winter in mountain areas, 1:5–10 (stronger anti-freeze effect). We don't recommend using it undiluted—it may damage rubber lines.
