Having a bit of a clear out at the moment and I just wondered if I should hold on to some old opened bags of lime. How long dose powdered lime keep once the bags have been opened?
I’ve got about two thirds of a bag of NHL5, a similar amount of NHL 2 and a small amount of Lime Hydrate. All are about 3 years old and have been kept indoors in their original opened bags and within plastic rubble sacks to stop the air getting to them. All still seem to be quite powdery. i.e. no obvious carbonated lumps and the base of the sacks still seem quite pliable when given a kick so it certainly hasn’t hardened at the bottom.. Can I still use this stuff, if not this year, then in the years to come?
