Had a chemical supplier offer some 12.5 SH at discount because it was 2 years old. Is it worth $4/gallon for 2ea 5-gallon pails? And how do I test SH when a vendor says it ok? Thx!

Mike I was always told sh has a shelf life of 12 Months if stored under the right conditions. So I would be careful may not save any money if it’s not effective. Ask the dealer to give you some to try but honestly I wouldn’t buy.
