To dilute screenwash, you generally need to mix screenwash concentrate with water according to the manufacturer's instructions, ensuring the correct ratio for effective cleaning and freeze protection.
Here's a breakdown of the process:
Steps to Dilute Screenwash
-
Check the Screenwash Concentrate Label: The most important step is to read the instructions on your screenwash concentrate bottle. This will tell you the recommended dilution ratio (e.g., 1:1, 1:2, 1:10). The ratio indicates the proportion of screenwash to water.
-
Choose the Correct Dilution Ratio: Select the appropriate dilution ratio based on the weather conditions and the level of protection you need. Higher concentrations of screenwash offer better freeze protection in colder climates. Some screenwash concentrates provide a chart indicating the freeze point for different dilution ratios.
-
Measure the Screenwash Concentrate: Using a clean measuring jug or container, pour the screenwash concentrate into the jug according to your chosen dilution ratio. For example, if you are aiming for a 1:1 dilution and need 1 liter total, measure 500ml of concentrate.
-
Add Water: Add water to the measuring jug, bringing the total volume to the desired amount. In our 1:1 example, you would add 500ml of water to the 500ml of screenwash concentrate to reach 1 liter total. Use clean, preferably distilled or deionized water, to prevent mineral deposits in your vehicle's washer system.
-
Mix Thoroughly: Stir the mixture well to ensure the screenwash concentrate and water are fully combined. A homogenous mixture will provide consistent cleaning and freeze protection.
-
Pour into Washer Reservoir: Carefully pour the diluted screenwash into your vehicle's windshield washer reservoir. Be careful not to overfill.
Example Dilution Ratios and Freeze Protection
While the exact freeze protection depends on the specific product, here's a general guide:
| Dilution Ratio (Screenwash : Water) | Approximate Freeze Protection |
|---|---|
| 1:1 | -34°C (-30°F) |
| 1:2 | -18°C (0°F) |
| 1:3 | -9°C (15°F) |
Important Considerations:
- Hard Water: If you have hard water, consider using distilled or deionized water to prevent mineral buildup in your washer system.
- Concentration: Always adhere to the manufacturer's recommended dilution ratios. Using too much concentrate can sometimes damage paint or wiper blades.
- Seasonal Adjustments: Adjust the dilution ratio according to the season. Use a higher concentration in winter for better freeze protection and a lower concentration in summer.
