Quick question re CRS

[will_raymo2000]

Does it have a shelf life? I think mine is 3-4 years old and just wondering whether it will have lost its effectiveness?

I did a quick search and even the manufacturer has no mention of shelf life on their website..

Thanks

Do you mean Calcium Reduction Solution or Carbonate Reduction Solution? Here is a link which may help.

I haven't got a clue about shelf life sorry.

Read this. AMS is the same as CRS.

It's just a dilute blend of sluphuric and hydrocholic acids. I can't think of a reason it wouldn't last indefinately.

sluphuric and hydrocholic acids..

So it's not just doctors' handwriting that's bad. :)
