It became interesting who washes the dishes with what solutions in their laboratory, write, share
Hi
When I worked in a lab we have utilized "usual" washing mixtures, the same as used in normal kitchens (Fairy etc.)
If the dishes are not contaminated with substances that are difficult to dissolve in water (fat, resin), then I wash it first with warm tap water, and then with distilled water. For washing dishes contaminated with fatty substances, I use soap, soda, as well as ordinary detergents.
Nobody washes with CrO3+H2SO4 mixture?
I've never washed it. But I know that the chrome mixture is a popular means for washing chemical dishes. In its presence, organic pollutants are perfectly removed. Do you use it for washing chemical dishes?
@argentum CrO3+H2SO4 is used for insoluble or hard-to-reach impurities. In my lab, for example, we soak glass filters and micro distillation flasks in it. In my oppinion it's the last choice solution 'couse it's a very dengerous compound. In day to day cases we use acetone, then ultrasound bath with dish soap and distilled water as a wash off.

Previously used in a student laboratory, now there is no need
The best dishwashing "solution" I know contains only sulfuric acid at its boiling point. Burns down all the organic impurities excluding silicon compouns (remains SiO2) and maybe PTFE. In the usual lab practice I use chromic mixture due to its "immortality" which is highly matter for a lab with less than 20 dirty flacks per year. Also azeotropic HNO3 works fine (reheat to taste)
