Having a clean and clear windshield is important for safe driving, especially during the darker days of fall and winter where visibility is already compromised. Your Honda’s windshield wiper fluid is an important part of this safety precaution and here are some pros and cons of different fluids:
Commercial fluids are designed to combat dirt and grime, reduce streaks, and repel water and are usually quite effective in keeping your windshield clean. However they are typically composed of detergents, anti-freeze and solvents which are toxic and environmentally harmful.
Using only water in the windshield fluid reservoir is not a good option since the water will freeze when the temperature drops below 32°. In addition, water alone is ineffective against dirt and grime, and can actually cause streaks and smears and reduce your visibility.
Although we can’t personally recommend the effectiveness, a number of different “green” homemade solutions can be found on the web if you want to give them a try. Here is one example:
- 1 empty (clean) gallon jug
- 1 gallon distilled water
- 1 tablespoon dish soap (such as Dawn)
- 1/2 cup non-sudsing ammonia (Note: You can substitute vinegar for ammonia if you prefer)
- A few drops of blue food coloring (optional, but a good idea because it serves as a reminder/warning of the contents)
- Mix all ingredients well before use, label the jug with the contents for safety.
