Does Muriatic acid go bad over time

[guamguy]

I found a gallon of MA in a storage closet at my house. It's probably a good 3-5 years old. Does anyone know if it would still be OK to use, or does this stuff loose strength or go bad after long periods of storage? Thanks

Muriatic acid stays fresh for a good long time. If the container is still sealed it should be fine.
