Solution

CrO3 is used as a cleansing agent for glassware. This is a solution of CrO3 in concentrated H2SO4. A premeasured mix is available under the name "Chromerge", which should be treated in the same way as aqua regia or acidic peroxide solutions because high-valent chromium is carcinogenic, teratogenic and causes severe environmental damage, the use of chromic acid is not recommended.

This is prepared as follows:

Na2Cr2O7saturated aq. solution+H2SO4conc.Na2SO4+2CrO3+H2O
