Chromic acid is very dangerous and spilling of this acid on floor can be very hazardous for the persons in the laboratory. Also pirhana solution and aqua regia requires large volume of acids which is not always economical. What are the other acid or chemicals we can use for cleaning laboratory glasswares. Chromic acid is a very good cleanser. Is there other non carcinogenic chemicals available which can clean like chromic acid?
There are some alkaline cleansing solutions, which are marketed as being a good substitute of chromic acid. The health risks are not to compare of course. We've been using "Mucasol" for several years with very good results. I actually don't have any own experience with chromates and piranhas, so I don't dare to say Mucasol really substitutes them but, nevertheless, you can keep your glassware sufficiently clean for many purposes, especially if you obey simple rules such as immediately cleaning the stuff after use and/or soaking it fully immersed in the cleanser for several hours.
Always depends what you want to remove, sometimes organic solvents can be used solely or in addition.
You can try mixture of iPrOH/KOH or EtOH/NaOH. These solution are good cleaning solution for organic contamination.
