Sodium Hypochlorite shelf life ?

[PPW1234 14]

I just got up and running in August and my season is already coming to a close. Going to start getting cold next week. Looks like I'm going to have 15 gallons of SH left over. I hear it looses it's potency over time. Will it be worth anything come spring or should I get rid of the stuff and buy new? If I double or tripled my SH % mix would it make a difference?

If it the SH is going to be useless, where does one get rid of 15 gallons of the stuff?

The guy I buy mine from keeps it in the freezer, I guess that helps the shelf life.

I've let a 15 gallon keg sit outside all winter here in Massachusetts and it was fine in the spring.

Good news. Thanks.

Keep it covered from direct sunlight in an approved "UV" protected tank ( dark blue ) and in a cool place. It should last a while.

It may not keep it's original %, but should last a while. Or sell another resi wash and just use it up.

Shock your clorine if it starts to weaken.

So no work to do for pressure washers in MI in winter?

Don't really no about "no work in Michigan" during the winter. This is my first winter. Found myself a heated storage unit so I could be ready to go if something came along. Do you keep busy there in Ohio during the winter?
