Then you have been very lucky!

I used to use acetone for dissolving certain plastics, and
in my PhD and postdoc days it was what we washed all our
glassware in as a first choice. It would, in time, remove
around 80% of the tarry crud I had left in the bottom of
flasks. The remaining 20% needed chromic acid.

I hate to think what the HSE would have thought of our
standard practice of a 5l beaker being filled with 2.5l of
sulphuric acid, pptassium dichromate being added and the
beaker just parked at the back of the bench so that the
cruddy flasks could be dropped in.
