Summer liquids should have good cleaning properties and not leave streaks on the glass. However, you should not use regular tap water, as it contains salts that are deposited in the nozzles and pump. This leads to a decrease in jet pressure and failure of the electronics.
Experts recommend checking the density of the liquid with a hydrometer before the start of the cold season. This will help ensure that the stated freezing point is correct. Saving on fluid can result in replacement costs washer reservoir and pumps.
- ✅ Choose liquids marked “For cars” and the appropriate temperature range.
- ✅ Avoid DIY mixtures based on industrial alcohol - they can damage the plastic.
- ✅ Use distilled water to dilute concentrates, not tap water.
- ✅ Check the quality certificate on the canister, especially when purchasing during the season.
