Can you use expired chlorine

Answer 1

The best thing to do is test a small amount of it on an unimportant area first to find out if it does any harm. Keep in mind that the fumes generated by pool chlorine are very strong and can be harmful to health in heavy concentrations.

Answer 2

Yes.

Actually, using it is the best way to get rid of it -- it is NOT safe to put it into the garbage.

But, you'll need to be careful. Old or "expired" chlorine may be weaker than you expect, and may have noxious fumes.

So, when you use it open it OUTSIDE, not inside a room or building. If it's been a long time since the container was opened, stand upwind, and turn your head away when you take the lid off the container. Let it 'air out' for a few minutes before trying to apply it to your pool.

Then, add a normal dose for your pool. But, a few hours after doing so, test your water, to make sure the chlorine level is what you'd expect. With old chlorine, you may have to use more than you normally would, to get the same results.
