Window lubricant is used as follows: 1. Clean the window rubber with a detergent brush; 2. Lower the window and take out the window lubricant; 3. Shake well before use, insert the nozzle into the spray hole; 4. Insert the nozzle into the window rubber groove and spray evenly up and down; 5. Wait for a moment, then wipe off any excess lubricant with a towel; 6. Test the window's up and down lubrication. Window maintenance methods include: 1. Regularly clean the window glass and tracks; 2. Regularly check the window switches and fuses; 3. Frequently lubricate the lifting mechanism; 4. Apply rubber protectant to the rubber parts supporting both ends of the glass.

I always keep window lubricant in my car, which I find extremely practical. Before using it, make sure to clean out small sand particles and fallen leaves stuck in the window gaps, otherwise spraying will just make it dirtier. Aim the nozzle at the rubber tracks on both sides of the window and spray—it's best to do it lightly and multiple times. After a couple of sprays, try raising and lowering the window a few times to let the lubricant seep in. In summer, prolonged exposure to the sun can cause the rubber seals to age and stick more easily, so I maintain them monthly. If you spray too much, it may drip down the door—just wipe it off with a damp cloth. Be careful not to spray on the inner side of the glass or the fabric of the door panel, as it might leave stains. When not in use, store the can in a cool place, as it can self-discharge in hot weather.

The garage master taught me a trick: the sunroof tracks also need maintenance. First, fully open the sunroof to expose the internal metal tracks, then use a fine cotton swab wrapped in cloth to remove old grease and grime. Gently shake the lubrication can, and spray at a 45-degree angle from 15 cm away from the tracks. Wait for it to penetrate for half an hour, then repeatedly open and close the sunroof seven or eight times. For the rubber seals, choose a specialized maintenance agent, apply it, and let it dry for twenty minutes before closing the window. It's best to do this in the morning, and avoid washing the car immediately after spraying. Metal tracks should be treated every three months, while rubber parts only need maintenance every six months.

It works exceptionally well in emergencies. Last time after a heavy rain, the car window was squeaking, so I used the small bottle of rubber lubricant that came with the car to spray the window tracks, and it became smooth immediately. Focus on spraying the vertical guide rails on both sides, two seconds each time is enough. Low-quality lubricants can corrode the rubber, so make sure to buy one with PTFE. Wiper blade chattering can also be fixed by spraying lubricant. Don't close the window immediately after spraying; wait three minutes to let the solvent evaporate.
