Would these or any of these (dry) chemicals: Metol, Sodium Sulfite, Hydroquinone, Borax keep indefinitely?

Stored well they all keep for years. I have Metol, Hydroquinone & Borax that's are at least 25 years old, some much older and they behave no differently than fresh supplies.

Thanks again Ian...25 years is indefinite enough for me:)

Keep your bulk chems dry, cool and in the dark, and they will generally last a looooong time. A couple like glycin are rather fleeting, but most are pretty tractable.

What color is glycijn when it goes bad from storage?
