A petri dish is a laboratory vessel used for microbial or cell culture, consisting of a flat disc-shaped bottom and a lid, generally made of glass or plastic. The materials of BUNSEN petri dishes are basically divided into two categories, mainly plastic and glass. Glass can be used for plant material, microbial culture and adherent culture of animal cells. The plastic ones may be polyethylene materials, which are disposable and multiple-use, suitable for laboratory inoculation, streaking, and bacterial isolation operations, and can be used for the cultivation of plant materials.

Generally, it goes through four steps of soaking, brushing, pickling, and cleaning.
1. Soaking: New or used glassware should be soaked in water first to soften and dissolve the attachments. The new glassware should be simply brushed with tap water, and then soaked in 5% hydrochloric acid overnight; the used glassware often has a large amount of protein and oil attached, which is not easy to be washed off after drying, so it should be immediately immersed in clean water after use for brushing.
2. Brushing: Put the soaked glassware in the detergent water, and brush repeatedly with a soft brush. Do not leave and prevent damage to the surface finish of the utensils. Wash and dry the cleaned glassware for pickling.
3. Pickling: Pickling is soaking the above-mentioned utensils in a cleaning solution, also known as acid solution, to remove possible residual substances on the surface of the utensils through the strong oxidation of the acid solution. Pickling should not be less than six hours, usually overnight or longer. Be careful when handling utensils.
