Is there expiration date for Malachite Green?
- Thread starter tiger15
- Start date
I have used a bottle that was 25 years old and the medication worked fine.
It is a stable dye.
However, I am a scrap metal dealer and know that gold does expire.
Send your old gold to me and I will dispose of it in an environmentally safe way free of charge.

Malachite green is a kind of organic dye, that beside turning things greenish, is anti fungal, anti protozoal, and anti bacterial.
It may have gotten more concentrated over the years, but not overly if closed tightly.
Used as directed it is toxic to aquarium parasites like ick, and fungal infections.
It is considered a carcinogen, so probably best not to get significant amounts on your skin.
