Summarize the following:
If you can physically see hair, dust, or some other contaminant trapped between the tint and the window, you won’t be able to fix it. Some air bubbles and mistakes will also be too stubborn to actually remove. In these cases, you can replace the tint on the window. If a professional shop installed your tint and there are visible mistakes, they’ll usually fix it free of charge. If it’s hotter than 65 °F (18 °C), you can use the sun to remove the tint. Drive your car out into the driveway or park it on the street to do this. You may want to remove the tint if you’re replacing it yourself, or to save some money at the tint shop. If you’re going to pay a professional to replace the tint, you can always take your vehicle to them and ask them to remove it. You’ll save yourself $15-30 in labor if you do this yourself though, and it’s not particularly hard to do. Grab a commercial glass cleaning spray. Open the door on your vehicle and spray the tint down with your glass cleaner. Really soak the tint to get the entire window soapy and wet. The glass cleaner won’t damage the interior, so don’t worry about drips. You can just wipe them away with a clean cloth. Grab a black trash bag or a sheet of black plastic. Spread the black plastic over the inside of the window and smooth it out over the door. Push the plastic against the glass with the palm of your hand. The plastic will stay in place since it will stick to the window cleaner. Make sure every section is covered by the plastic. Close the vehicle door and let the trash bag stick out around the sides of the door. Let the vehicle sit in the sun for 20 minutes if it’s 80 °F (27 °C) or hotter. If it’s a little on the cooler side, wait a little longer. The plastic insulates the window as the sun heats the glass up. The adhesive will melt while it sits out on the sun and make removing the plastic easy. You can achieve the same effect with a heat gun, but this is much easier and safer for your vehicle. After the vehicle has sat out in the sun for a while or after you’ve heated it with the heat gun, open the door and peel the black plastic bag off the window. The tint should have wrinkled up a little in the sun. If it did, grab a wrinkle near the edge of the window and slowly peel the tint off like you’re removing a sticker. If you can’t do it by hand, grab a metal straight edge, like a razor blade, and scrape the tint with the edge to peel it off in strips. Either go back to the shop where you got the tint, or look up a tint shop in your area. Take your vehicle to the professionals and pay them to replace your window. This is the best way to ensure you don’t end up with a bad tint job. It typically costs $100-400 to tint an entire vehicle, but it will cost considerably less to get a single window replaced. if you want to install the tint yourself. If you installed the tint on your own, you already know what you’re doing. The odds are high that your main mistake was not cleaning your window enough, or not smoothing the tint out with your straight edge correctly. This time, spend an extra 5-10 minutes cleaning the window with soapy water and spend an extra 10-15 minutes smoothing it out when you reinstall the tint. Tinting a vehicle is a pretty touchy process. If your first attempt to tint your windows was unsuccessful, you likely got enough practice to nail the process this time.
