Heat, sunlight & muriatic acid

[larry2338]

Is stored muriatic acid degraded by sun and heat like chlorine is?

Anyone know?

Good question, I store mine out of the heat and light just in case, but I'd love to know if there's any degradation. I could store it closer to "point-of-use" if the heat doesn't somehow degrade it.
