Compared to ordinary glass, glass tempered in a tempering furnace is safer and has better bending resistance, but it is still glass after all, and improper use can cause it to break. Therefore, care must still be taken during daily use to ensure the service life of the tempered glass. Today, Auto Tempering Furnace manufacturer will teach you how to clean and maintain tempered glass and precautions.

　　Cleaning Tempered Glass

　　1. Daily cleaning with a damp towel or newspaper

　　For daily cleaning, simply wipe with a damp towel or newspaper. A damp towel can remove most stains, and a newspaper can remove water marks from the glass surface; stubborn stains can be removed with a towel dipped in beer or warm vinegar, or glass cleaner can be used. Avoid cleaning with strongly acidic or alkaline solutions; in winter, frost easily forms on the glass surface, which can be effectively wiped off with a cloth dipped in concentrated salt water or white wine.

　　2. Cling film gives glass a new life

　　Glass covered in oil stains is very difficult to clean. All you need is a piece of cling film and a damp cloth to give the glass a new lease of life: Spray cleaner on the glass, apply a piece of cling film to soften the solidified oil stains. After ten minutes, remove the cling film and wipe with a damp cloth to remove all the oil stains, leaving it spotless and smooth as new; If there are oil pen marks on the glass, you can use a water-soaked eraser to rub them, and then wipe them with a damp cloth to completely remove the oil pen marks; If it is paint, you can use cotton dipped in hot vinegar to clean it; wiping the glass with a clean dry cloth dipped in alcohol will make it crystal clear.

　　3. Non-fluoride toothpaste for cleaning frosted glass

　　Various patterned frosted glass and sandblasted glass are also popular, but they are more difficult to clean. To clean patterned frosted glass, you can use a toothbrush dipped in cleaning agent or non-fluoride toothpaste to scrub the stained areas to completely remove the stains. Do not use fluoride toothpaste, as fluoride will damage tempered glass. Maintenance of tempered glass dining tables

　　1. Avoid prolonged sun exposure and rain

　　If the glass dining table is exposed to prolonged sunlight or rain, the edge seams are likely to crack, causing the base material to expand and deform, and the glass to shatter. If this happens, it must be returned to the factory for repair;

　　2. Handle items gently

　　Remember not to bump the glass surface forcefully, and handle items gently when placing them. To prevent scratching the glass surface, it is best to place a tablecloth or table mat;

　　3. Keep clean to prevent mildew

　　The tempered glass tabletop should be kept clean regularly to prevent mildew stains from forming due to surface contamination. If mildew stains occur, you can move the dining table to a ventilated place and iron the stained areas with an electric iron for 2-3 minutes until the mildew stains disappear;

　　4. Wipe away tea spills promptly

　　Tea spills on the tabletop should be wiped away promptly, otherwise they will leave unsightly tea stains over time. To remove tea stains, you can sprinkle some water on the table, then wipe it with tin foil from a cigarette pack, and finally wash it with water to remove the tea stains;

　　5. Hard cloth and wax to remove scorch marks

　　Sometimes, if a cigarette accidentally falls on the tabletop, unsightly scorch marks may be left on the glass surface. You can wrap a hard cloth around a toothpick and gently wipe the scorch marks, then apply a layer of wax to remove them.

　 　Precautions for Tempered Glass Products

　　1. Pay attention to protecting the corners and edges of tempered glass

　　If the corners and edges of glass tempered in a tempering furnace are damaged, the risk of spontaneous glass breakage increases exponentially. Because the stress points of tempered glass are all concentrated at the corners and edges, the protection of the corners and edges is particularly important. For tempered glass with damaged corners and edges, care must be taken when using it;

　　2. Avoid prolonged pressure on tempered glass

　　For aesthetics, many families choose to use tempered glass as the tabletop for their coffee tables. Generally, the pressure resistance of glass processed by a tempering furnace is between 70mpa and 100mpa. This pressure multiplied by the bearing area of the glass is the maximum pressure it can withstand. Converted to item weight = (pressure * area) / 10, unless necessary, do not place heavy objects on the tempered glass tabletop for long periods of time to avoid the pressure reaching the critical point and causing the tempered glass to break;

　　3. Avoid uneven heating and cooling

　　Under extreme conditions, if high and low temperatures are applied to both ends of a piece of glass, there is a 90% chance that the glass will explode spontaneously. For example, if you pour cold water on a lit incandescent bulb, the glass of the incandescent bulb will break. Although the probability of this happening to tempered glass is very low, it is better to be safe than sorry;

　　4. Keep away from acidic and alkaline substances

　　Avoid contact between tempered glass and alkaline substances such as sodium hydroxide (NaOH, caustic soda). Glass is essentially silicon dioxide (SiO2) and will react chemically with these substances;

　　5. Do not strike the corners and edges of the glass with sharp or hard objects

　　Since the stress points of tempered glass are concentrated at the corners and edges, once the corners and edges are broken, the likelihood of the tempered glass breaking increases. Therefore, for home safety, do not strike the corners and edges of the tempered glass with sharp or hard objects.
