First of all, you need to make sure your windshield is cleaned before application. Any contaminants will affect how Rain-X works on the windshield. Specifically, if your car has been through a car wash, you need to take off all the silicones and waxes first. Remember to use an abrasive cleaner to have the best result.

​Secondly, apply Rain-X to a dry screen with a dry and soft cloth in a circular and overlapping motion. Let it dry and then reapply to ensure a full coverage. When a haze forms, remove it with a lint free cloth and paper towel from bottom to the top. Repeat it a few times for greater results.

Make sure to carefully clean your windshield and remove all the debris and dust with a dry and soft rag first. This is needed to be done in order to avoid scratches during treatment.

After that, you need to use mild detergent and a wet rag to wipe it all down the windshield. You can also use dishwashing liquid instead of mild detergent.

Mix the mild detergent with water with a right amount. It is recommended using a generous amount for the desired outcome.

If you don’t have any dishwasher left, you can use vinegar instead. Vinegar itself has excellent cleaning properties that can help to remove most of the smears off your car windows.

Step 2: Testing Your Abrasive Cleanser

Because Rain-X has a hydrophobic formula that designed to fill all the tiny pores in the windshield, cleaning the windshield just water and soap will not help to remove it completely. You need to use a wet sponge to apply abrasive cleanser or anything with scrubbing power.

​Remember to apply the abrasive cleanser on the wet sponge, not directly on the windshield. Read the instruction carefully and don’t use a cleanser that will damage your windshield’s surface.

Start to scrub by testing in a small area first. While you are scrubbing, you also need to check is there any scratches on the windshield. If there is any scratch, then your cleanser is not suitable. If there is no scratch at all, you can continue to use this abrasive cleanser for your car windows.​

For a better protection, you can ask a mechanic to find out which kinds of products are effective and safe at getting off Rain-X residues from the windshield or car windows. This will help you avoid using the wrong type of cleaners and permanently damage your car.​

Step 3: Scrubbing the Entire Windshield Using Abrasive Cleanser

After you found the right type abrasive cleanser for your windshield, you can now start to scrub the whole windshield. Apply the appropriate amount of cleanser directly to the sponge and start to scrub your windshield. Do it from one side to the other in a circular motion to work the cleanser into the problem areas.​

Remember to keep your sponge wet and soapy all the time throughout the cleaning to avoid scratching. You don’t want your sponge to leave marks on the windshield.​

A good scrubber is also a good option because it is gentle but still coarse enough to scrub the haze.​

Step 4: Thoroughly Rinse the Windshield With Fresh Cold Water

When you’ve done with step 3, you need to wash your windshield thoroughly with adequate water. Use a sponge and a hose with a nozzle to gently wipe down all the cleanser and the entire remaining Rain-X residue.​

You can also use a spray bottle or wet cloth for the cleaning. In addition, it is the best to use fresh cold water for this step. After that, let it dry and you can see if all the Rain-X has been removed. If your windshield is not still clean, you can use a commercial cleaner to eliminate the remaining stubborn haze.​

Afterward, apply a generous amount of the commercial cleaner onto the sponge. Remember to read carefully the instructions to make sure that you use a commercial cleaner with a right amount.​

Use that sponge to wipe off all the remaining stubborn haze on the surface of the windshield. Focus on the areas with the residue. Keep cleaning the windshield in a circular motion until the haze is eliminated. After that, rinse your car off with fresh cold water.​

After cleaning the windshield, dry off the windshield with a soft rag. The result will be a clean windshield free of the film and residue.
