Step-by-Step Guide to Make Car Washer Fluid
Follow these steps carefully to make your own washer fluid:
Step 1: Prepare Your Container
Use a clean bottle or jug. Wash it well if it is old. Rinse with water to remove dirt. Dry it before use. This keeps the fluid clean.
Step 2: Add Water
Pour 3 cups of water into the container. Distilled water is best because it has no minerals. Minerals can clog the car washer system. If you have only tap water, it will still work.
Step 3: Add Rubbing Alcohol
Add 1 cup of rubbing alcohol to the water. Alcohol helps the fluid to freeze less in cold weather. It also cleans dirt well. Be careful while handling alcohol. Keep it away from fire.
Step 4: Add Dish Soap
Add 1 teaspoon of dish soap. Soap helps to remove grease and grime. Use mild dish soap. Too much soap can make bubbles and leave marks on glass.
Step 5: Add White Vinegar (optional)
You can add 1/2 cup of white vinegar. Vinegar helps remove bugs and dirt better. It also stops mold from growing inside the fluid. Vinegar is safe and natural.
Step 6: Mix The Fluid
Put the cap on the container. Shake it gently to mix all ingredients. Make sure everything blends well.
How to Use Your Homemade Car Washer Fluid
Use the fluid the same way as store-bought fluid. Pour it into the windshield washer tank in your car. Check your car manual for the tank location. After filling, use the washer button to spray the fluid. It will clean your windshield and improve visibility.
