I bought S weetex Hi Ratio about 1 year ago. This huge box doesn't have a expire date on it.
Does Hi Ratio expire in 1 year?
AThe box should at least have an encoded lot number, if you contact the mfr they should be able to tell you when it was made. If it's stored in an airtight container away from heat and light it should be OK for 1-2 years, you'll know by the smell if it has gone bad.
AThanks for the info! I will look for the code.
