Sort:  

I always used this rule (weak > strong vs most common plastics):
H2O < 70% isopropanol < methanol < ethanol < acetonitrile < ether, THF < acetone < benzene, toluene, hydrocarbons << dimethylformamide (DMF), N-methylpyrolidone (NMP). I broke a gallon jug of NMP and it turned the special lab floor tiles to semisolid putty!

I'm going to have to mention this. One of our lab mates did not understand the difference between denatured and non-denatured. Some of the denaturants in that batch were benzene, toluene, and naptha. There's now some plasticware we no longer need to disinfect...
