The methods to remove the rain guard film from the rearview mirror are: 1. Use a warm air blower or hairdryer to heat the rain guard film and then peel it off directly; 2. Locate the edge of the rain guard film at the corner of the rearview mirror and slowly peel it off. The adjustment methods for rearview mirrors are divided into: external adjustment and internal adjustment. Based on installation position, they are categorized as: interior rearview mirror, exterior rearview mirror, and under-mirror. The adjustment methods for rearview mirrors are: 1. Adjust the horizon reflection in the center rearview mirror to the middle of the mirror, and the reflection of the right ear to the left edge of the mirror; 2. Adjust the horizon reflection in the rearview mirror to the middle of the mirror, and the reflection of the left side of the car body to occupy one-fourth of the right side of the mirror; 3. Adjust the horizon reflection in the rearview mirror to two-thirds of the mirror's height, and the reflection of the right side of the car body to occupy one-fourth of the left side of the mirror.

I also have a rain guard film on my car, which started causing issues after prolonged use, so I needed to remove it carefully. I used a hairdryer to heat the film surface for a few minutes to soften the adhesive, then gently peeled it starting from the edges with a plastic scraper or card. Remember, never use metal tools as they can easily scratch the mirror. After removing the film, I had to deal with the leftover adhesive—I tried rubbing alcohol or essential balm, wiping it clean with a soft cloth. The whole process took me about half an hour because patience is key; rushing might damage it. Before applying a new film, it's best to clean the mirror surface with a dry cloth to avoid dust. DIY-ing this was quite satisfying, but I recommend doing it on a sunny day when humidity is lower for easier handling.

When I was dealing with the rain film, I learned a few tricks. Starting from the edge is key. Use a hairdryer to blow for two to three minutes, the heat will soften the adhesive, then slowly pull it off while wearing gloves. If there's a lot of residual adhesive, pour some cooking oil on a cloth and wipe it off—it works well and saves effort. Be careful not to spray chemical cleaners on the mirror surface to avoid corrosion. After finishing, check if the mirror surface is clear, and polish it promptly if there's any wear. Personally, I think this kind of saves money on repair shops, but safety comes first—do it after parking.

Removing the rain guard film is actually not difficult. The key is to heat it to soften the adhesive, which can be done with a household hair dryer. Peel it off slowly starting from one corner to avoid forceful pulling. After cleaning the adhesive residue, use alcohol or a mild cleaner. Be careful not to injure yourself or the mirror during the process; wearing gloves is safer. If needed, a new film and applying it back is also very simple.

I pay special attention to protecting the mirror surface. When applying the rain repellent film, first find a shaded area to avoid direct sunlight affecting the application. After using a hairdryer to heat the film, slowly scrape it off with a plastic card. For cleaning residual adhesive, use a small amount of olive oil or soapy water to scrub, avoiding strong solvents to prevent damage. Afterwards, you can apply new car wax for protection. The entire process takes about 20 minutes to ensure a smooth and clean finish.

Money-saving trick for rain repellent film: Use a hairdryer to heat it up and peel it off slowly, then clean the adhesive residue with kitchen detergent. Don't waste money on tools, an old card will do. After finishing, spray some anti-fog spray to enhance the effect. DIY saves you dozens of dollars in shop fees, but make sure the mirror isn't damaged.
