Here are some methods and things to pay attention to when cleaning and maintaining fixed seats in universities:

1. University fixed seats should be placed in a dry place with good air circulation, not close to fire sources or damp walls, and avoid sun exposure.

2. When cleaning the wooden materials used in the fixed seats of the university, use a soft cloth that has been wrung out and does not drip. To avoid excessive moisture causing wood rot, if water-containing substances are spilled on the ground, wipe them dry immediately with a dry rag. Never scrub with alkaline water, soapy water, or detergent solution to avoid chemical reactions that may cause corrosion and parts falling off.

3. Avoid frequent contact with water for the steel parts of university fixed seats. Wipe with a damp cloth and then wipe again with a dry cloth to prevent internal rust.

4. When moving fixed university seats, lift them off the ground and do not push or pull hard to avoid loosening or damaging the table legs and chair legs, and to reduce damage to the ground.

5. Avoid placing acid and alkali corrosive substances on fixed seats in universities.

6. Avoid throwing and smashing university fixed seats, causing parts to become loose or protruding, or even deformed.

7. The school should conduct a comprehensive inspection and replacement of fixed seats in the university regularly, and the time should be controlled every 3-6 months.

Four ways to remove stains on desk tops:

1. Correction fluid

Correction fluid is indispensable for students. Many students will get correction fluid on the desktop, so how should they clean it up? Dilute it with toothpaste and wipe it with a rag to remove it.

2. Traces of ballpoint pens and other oil-based pens

Traces of ballpoint pens can be completely removed by wiping with vinegar.

3. Double-sided tape, transparent tape

Some students will stick their grades, goals, etc. on their desks with transparent tape. When they are removed, sticky glue will be left behind. You can first remove the paper on the surface with water, and the remaining gum can be wiped off with wind oil essence. The effect is obvious.

4. Pencil mark

Some desktops that have been used for a long time will have stubborn pencil stains. You can wipe them with an eraser first. If they cannot be wiped off, spread a hot towel on the desktop and let it sit for a while, and then wipe it back and forth.
