Or You Could Try Looking It Up On Google
A careless undergrad spilled some crystal violet on the lab bench earlier in the week. Here are some chemicals that we tried on the stains and the results:
Water – Nothing.
Ethanol – Some of it came off, but the majority stayed.
Isopropyl alcohol – Nothing.
Acetone – Nothing.
Hydrochloric acid – It bleached the stains.
Acetic acid – Yay! It worked.
