How to deal with the stains on the experimental reagent cabinet

It depends on what kind of stain it belongs to, and different stains use different reagents.

Common stain removal methods are as follows:

Greasy stains: Use No. 120 solvent gasoline, or chemical organic solvents such as trichloroethylene, tetrachloroethylene, benzene, etc., dip a small brown brush or small towel in chemicals, and gently scrub or scrub the stains repeatedly. The grease and gasoline in the stain are dissolved, and the stain gradually disappears as the chemical agent evaporates.

It should be noted that traces often appear after the oil stain is removed, and the reason is that the oil does not completely evaporate after dissolving and remains on the fabric. The removal method is to put No. 120 solvent gasoline in a watering can, spray evenly around the traces, the area should be larger, and the traces can be removed by rolling them with a clean towel while spraying.

Fatty pigment stains.

You can choose No. 120 solvent gasoline, xylene, alcohol or xylene alcohol soap, gently scrub it by hand, and then wash it with low-temperature soap after the grease in the stain is removed.

Paint stains. For newly polluted paint stains, it is necessary to dip a small brown brush in banana water or carbon tetrachloride, benzene, gasoline and other organic solvents in time, gently scrub them, and then wash them with low-temperature soap and rinse them.

For old paint stains, first soak them with No. 120 solvent gasoline to loosen the bond between the stain and the fabric, and then remove them with banana water and benzene. If the stain on the white cotton-polyester fabric is a large area of paint stains, the ideal removal effect can also be achieved by using low-concentration caustic soda soap liquid and high-temperature soap boiling method.

Rust stains. For the removal of this stain, you can choose to soak it in acetic acid solution, and the stain can be removed through a chemical reaction.

Potassium permanganate stains.

To remove this stain, you can choose to soak it in baking soda solution, and the stain can be removed through a chemical reaction. This method is also suitable for stain removal in a variety of materials and colors.

Glue stains. This stain can be removed with the organic solvent acetone. Because acetone dissolves 502 glue.

Iodine wine stains. It can be removed with high-quality solvent alcohol or potassium iodide. When preparing, you can use 100 ml of water to add potassium iodide 5 to 7 grams. Be sure to rinse clean after removal.

Purple potion stains. The ingredients of this potion are mainly extracted from gentian grass and are plant pigments. A part of the pigment can be removed with solvent alcohol, and then bleached with an oxidant sodium hypochlorite solution.

There is no need, the dangerous reagent is also in the bottle, but the bottle ** is used in a safety cabinet, and if you are worried about the smell of the reagent, you can install a ventilation device, which is a ventilated reagent cabinet

According to the regulations, the processing of various reagents needs to be handed over to a special company.

Spray it with descaler, and after 15 minutes, wipe it with a steel wool ball, and it's OK. Prepare a few more steel wool balls, because the steel wool balls will be full of sticky grease.

Tile floors with the same method. Wooden floors are not OK because they will wipe off the paint. Spray the wooden floor with Mr. Vermeer and other descalers, and after 15 minutes, wipe it with the flower bulbs used for bathing, because the texture of the flower bulbs is relatively hard, and the wiping effect is good and does not hurt the paint.

The crystal stone is very beautiful, but it needs to be taken care of often. Cabinet countertops are best made of composite acrylic, or full acrylic. It is very stain-resistant and can be resistant to acids and alkalis.

There aren't so many worlds coming back, and categorizing can actually put together harmless realities.

There aren't so many centuries expensive to classify reagents that should be the same grouped together.

You still have a lot of practical words, and it was more convenient to use it this way at that time.

Well, if you classify the world, you just need to adjust it, and there are many of these actually expensive.

What if there aren't so many things to classify morale? This is also a substitute for other products.

Cabinet countertop cleaning and maintenance.

DU Tips:

1. Remember not to use a steel wire to brush it, as it may scratch the artificial stone back to the countertop, use a cleaning cloth to stick the dish soap with water and then wipe it with a dry rag.

2. For a long time (more than 12 hours) let water, soy sauce, vinegar and other liquids stay on the countertop, which may damage the surface of the countertop.

3. Look at the degree of dirt and dirt. Put an appropriate amount of laundry detergent and warm water, soak it in a tank basin for about half an hour according to the appropriate proportion, and then wipe it with a cleaning cloth.

4. First use coarse sandpaper sand to remove scratches, and then use 400, 600, 800, 1000, 1200, 1500 and other sandpaper water grinding. Then polish it with a dry cotton ball with a spray bead.

5. If there are rubber, nail polish, paint and other sticky substances that are particularly difficult to remove on the countertop, you can use a knife to gently scrape them off if necessary, and control the strength when scraping off to avoid damage to the countertop.

6. The artificial stone cabinet countertop will generally not be burned by high-temperature items, but avoid placing the items directly on the artificial stone cabinet countertop or local heating of the cabinet countertop for a long time. Do not place hot household items directly on the countertop to dissipate heat, and it is recommended to use special thermal insulation pads or thermal insulation brackets to place your belongings.

Hello, I am doing marble, you said this situation, you have to see what is on the white countertop, if it is an oil stain, it is likely to have entered the inside of the stone, polishing is not good, is the stone special stain remover, it really does not work to change a piece,

White marble does not have a good anti-fouling function. After being contaminated, you can only go to the building materials market to buy cleaning liquids that are specially used to clean stones. If you don't know how to clean, it's time to find a professional. [Ask in the stone building materials market, do stone knows].

Depending on the type of stain, different methods should be used (see below for details).

2.Resolution.

1) When removing stains from marble, remember that you must use neutral detergents, not those that contain bleaching properties. Also do not use hard brushes and abrasive cleaners. As with any stone, the best way to prevent marble stains is to clean up spills.

Some owners will use a variety of different sealants to protect the marble surface, but reseal them regularly either way.

2) Acidic stains.

Blotting the stain is far better than wiping it off, as wiping it will cause the stain to spread. Most stains, such as vinegar or juice, can be removed with a paste made from baking powder and soda. After the paste is dry and hardened, wipe off the paste with a damp towel and dry it with a dry towel.

3) Food stains.

Hardened food stains can be removed with hydrogen peroxide, but not for too long. Once the stain is gone, wipe it clean with a damp rag and finally dry it.

4) Grease stains.

Use a paper towel to absorb the grease and then sprinkle it on the stained area with an absorbent such as white powder. Leave for 1 to 2 hours. Then wipe with a damp cloth and finally dry.

5) Nail polish stains.

Put a few drops of dishwashing liquid in about half a liter of warm water and wipe with a clean white cloth. Do not leave dishwashing liquid behind, wipe off any remaining liquid with another damp cloth and wipe dry. Repeat cleaning until the stain is completely removed.

3.Precautions.

There are a lot of neutral sealants on the market that won't damage the marble surface. However, these sealants need to be resealed periodically depending on the type of marble. For example, marble floors need to be resealed every 6 months, while kitchen countertops can be sealed for up to a year.

The natural porosity of marble makes sealing crucial.

Remove dirt and dust from the soles of your shoes before entering the door. It's best to put a doormat at the door. Also, do not use acidic substances such as vinegar, non-alkaline detergents, etc. to remove stains from marble.

If the staining is severe, don't try to take homemade remedies that you're not sure about. It's best to have a professional handle it. end

Wash it with gasoline, it works or use five cleaning powder, I use this, it's very easy to use!
