Water sprinkled on the glass, there are white marks after drying, why?

The composition of glass water is water, alcohol, ethylene glycol, corrosion inhibitors and a variety of surfactants, among which ethanol, ethylene glycol, corrosion inhibitors and surfactants are organic solvents with good performance, which will react with the paint on the floor surface, and will leave white marks if not erased in time. But don't worry too much, the concentration of active ingredients in glass water is very low, but it reacts with the superficial layer of floor paint, the depth is limited, and the usual use and cleaning and scrubbing of the floor will reduce the traces, and after a long time, it will gradually disappear. Therefore, there is no need to deal with it deliberately, and there is no good and effective way.

Wiper water should be called washing liquid. The white residue is the preservative sodium nitrite, which is sprayed on the glass due to excessive addition. Actually, you can do it yourself.

According to the automotive industry standard (QCT 246-1997 Technical Conditions for Electric Scrubbers for Automobile Windshields) for washing liquids

Water with a hardness of less than 205g 1000kg (that is, ordinary tap water) is added to an appropriate amount of commercial additives in winter.

The so-called commercial additives are antifreeze, generally adding alcohol or glycerin, and their proportions are.

The proportion of antifreeze additives can withstand minus 20 degrees Celsius, and if you want to freeze at a lower temperature, you only need to increase the ratio of alcohol or glycerin.

Therefore, as long as the hardness is less than 205g and 1000kg of water can be used, if the ambient temperature is required, the appropriate amount of commercial additives (i.e. alcohol or glycerin).Some need to add a little transparent pigment in an appropriate amount for commercial identification, and do not use washing liquid in order to prevent a long time. Water microorganisms multiply cause water quality to deteriorate and stink, you need to add a little preservative (sodium nitrite) in an appropriate amount, the capacity of the water tank is generally, if it can be used up within 2 or 3 months, there is no need to add preservatives at all.

The composition of glass water contains alkali, and after spraying dry, it is the residue of alkali, just wipe it off.

How to clean glass?

1. Sweep away the large dust on the frame and wipe the border.

2. Clean the surface stains with water, and use dish soap and a small blade if necessary.

3. Scrape off water with glass.

4. Use a dry towel or newspaper to wipe off the surface water traces.

5. Remove the dust in the frame and groove.

Why is it that dry towels and newspapers are not clean, leaving some shiny traces like wiping the mirror of the bathroom with a sanitary napkin?

This still doesn't clean the surface. You can wipe it with dish soap, then wipe it with water, then scrape off the water, and then wipe it with a dry towel or newspaper. Let's see, isn't it much cleaner?

Why can you wipe glass with newspaper?

This is because newspapers are highly absorbent and do not shed hair like towels. These are its two great things. Another point is that there is a layer of ink on the newspaper, which can make your glass brighter.

Use a slightly moist sponge and it will come off.

Easy way: Wipe it with newspaper.

If you have just soaked for a period of time, there will be white particles on the inner wall of the glass, that is, before soaking wine, after the glass bottle is washed, there is no drainage, or the glass bottle is directly used to grind the soaking wine without being processed by the trouble, and the soaking wine is famous, and there is a white flocculent object, usually one is that the soaking wine bottle does not control the dry water, and the other is that the material is not drained before soaking the wine, in this case, the white particle object is attached to the surface of the soaking wine material first, and with the passage of soaking time, it even becomes flocculent. The third is that it is not sealed and stored, and in this case, the capacity forms a layer of white hairy objects on the surface of the wine.
