How to ensure that laboratory instruments remain in good condition?

A new Anton Paar Abbemat 300 automatic refractometer was recently acquired. After comparing the data obtained with titration over the past couple of days, it has now been put into regular use, primarily for analyzing the concentration of hydrogen peroxide, the concentration of liquid sodium hydroxide, and the salinity of solutions. But yesterday, I suddenly noticed that a piece of paint had fallen off the surface of the instrument, and the paint in the surrounding area also showed wrinkles. The manager was very upset when he saw this. Many of the instruments in our laboratory are damaged in appearance; the area around the gas chromatography injection port has changed color, and there are also stains on the body of the Mettler 915 moisture meter that cannot be removed. How do everyone maintain the appearance of their instruments? Are there any good methods?
It is recommended to look for the causes in terms of operational standards and indoor ventilation. For example, when the exhaust fan is turned on, it is necessary to ensure that there is an inlet for supplying fresh air into the room. Installing exhaust fans in a sealed room will not ensure the reduction of harmful gas emissions. Damage to the instrument’s paint finish is likely related to the levels of harmful gases in the environment; for reference only.
Pay attention to hygiene when using it, and clean it up promptly after use
I would like to ask the original poster: the tableware you use has suffered some minor visual damage after being used for a long time, but it still holds delicious food. Do you think this has any impact on the taste of the food?
