Can the plastic empty cream jar be cleaned with a brush?

Plastic empty cream jars can indeed be cleaned with a brush. It is very important to choose the appropriate brush and follow the correct cleaning steps during the cleaning process.
Firstly, ensure that the selected brush material does not cause scratches or damage to the plastic can. Soft bristle brushes or nylon brushes are safer and more common choices because they can effectively remove dirt without causing damage to the plastic surface.
Secondly, before cleaning, it is advisable to pour out as much residue as possible from the plastic can and rinse the inner and outer surfaces of the can with clean water to remove much of the dirt. If the dirt is stubborn, you can add an appropriate amount of detergent (such as dishwashing detergent, shower gel, etc.) to clean water and soak the plastic can in the solution for a period of time to soften the dirt.
Then, gently brush the inner and outer surfaces of the jar, especially the corners and gaps, to remove any remaining dirt and cosmetic residue. During the brushing process, excessive force should be avoided to avoid scratching the surface of the can or damaging its structure.
Finally, thoroughly rinse the inner and outer surfaces of the jar with clean water to ensure that there are no residual detergents or dirt. Afterwards, place the cleaned jar in a well ventilated area to air dry naturally, avoiding prolonged exposure to sunlight or high temperatures.
In short, plastic empty cream jars can be cleaned with a brush, but it is important to choose the appropriate brush and follow the correct cleaning steps to ensure cleaning effectiveness and the integrity of the plastic can.
