test bench is an important facility in the laboratory. However, we all know that there will be dirt after long-term use, so how should we clean it?

1. For general cleaning, we can use 70% ethanol solution to scrub the countertop, or wipe it with clean water. For dirt that is difficult to wipe off, we can apply a small amount of household detergent and use a brush to scrub the dirt area. Of course, be careful not to use corrosive detergents, which will affect the integrity of the countertop and the experimental process.

2. If there is dirt caused by other chemical residues on the desktop, then we should use the corresponding chemicals to deal with it.

3. If you want the experimental table to be more shiny, you can use a solution such as bright oil to scrub the table, which will restore the gloss to the table that was scratched during the experiment.
