Methanol cannot be added to car glass water, because adding methanol will destroy the performance of car glass water. Therefore, ethylene glycol is used to make glass water instead of methanol.
High-quality glass water is mainly composed of water, alcohol, ethylene glycol, corrosion inhibitors and various surfactants. According to the properties, it can be divided into solid glass water and liquid glass water. Among them, solid glass water is mainly used in environments above 0℃. Making your own glass of liquid water also requires considering freezing issues in cold climates.
For frequent driving, especially in dusty environments, and when driving on highways on rainy days, the water in the glass will be consumed very quickly. It is therefore particularly important to replenish the glass of water in time.Some car owners will choose to make their own water glass, which is cheap and hassle-free.

Yes? ! The wiper will vibrate and make noise if it is covered in rain.
I have already experienced this. I often spray glass water. The glass water formula is definitely not alcohol mixed with water. My glass water is tap water + oil film remover + ready-made glass water purchased from general automotive supply stores... Later, after going through the glass water,car wash, rain and weather, it took about 4 or 5 days to cure. Then I knew I should never use Rain Enemy again! My rain foes are only used on the side windows and headlight windows. good results!
This effect is not obvious, it is better to polish the glass;
The first step, cleaning and preparing the glass surface before glass polishing< /p>
1. Wrap masking tape around the edge of the window being repaired to prevent it from staining the car and surrounding area when the window is polished.
2. Clean the glass surface and sandpaper carefully to avoid dust, sand, etc.
3. Glass PolishingBefore polishing, first use a marker to circle the area to be polished and repaired on the back of the glass to avoid shifting and too large a polishing area.
The second step, use P120#, P240#, P40 sandpaper0#, P600# to remove scratches on glass
1 Pay attention to the sandpaper pattern here and daily hand. discarded sandpaper The model markings are different and cannot be mixed with daily sandpaper.
2. Pour in a little polishing solution if necessary and dilute it with water in a ratio of 1:1, not more than 1:5. It is specially used for polishing sandpaper.
3. There should be enough polishing liquid for scratch polishing. Sandpaper may not be dry sanded directly on the glass surface at any time.
A. Deep scratches (obvious to touch): first grind with P120# sandpaper --- then polish with P240# --- polish again with P600# sandpaper to make the surface. For final polishing requirements, you can also omit this item and go straight to step three.
B. LightScratches (no touch feeling but white marks): initial grinding with P400# sandpaper --- polish again with P600# sandpaper to make the surface meet final polishing requirements. Omit this item and go straight to step three.
The third step is to add polishing liquid and use a special polishing wheel to polish and restore the transparency of the glass
1. Wipe the glass and observe the polishing range of the sandpaper, apply polishing liquid and use a special polishing wheel (use appropriate pressure (the polishing machine plate and the glass surface should be flat) to polishing. If there is no polishing machine, you can use manual polishing discs to polish. Be careful not to move too quickly at this time and polish carefully to ensure the effect. p>2. If the gloss is not good, repeat steps c.above
This operation is also suitable for polishing various scratches on various glass surfaces in daily life
Note: Although scratches with a depth of more than 100 microns may be removed by polishing, the safety performance of the glass will be affected after polishing. In particular, scratches with a depth of more than 100 microns on the surface of car windshields are not. suitable for polishing.
A simple summary: first use wet sanding sandpaper to gradually remove the marks, then use a polishing disc and polishing liquid to polish and make it translucent.
