I use this because its cheap, and I like to make a solution that I re-use for a while. What is the proper amount of Sodium Metabisulfite per gallon of water to make a solution for sanitizing equipment and jugs? If I could get the measurement in tsp or tbsp, that would be good.
I have done this before, but I cannot remember how much I used. I had a 2 oz package of it, so I think I used 1 oz and made a half gallon batch of solution, but I cannot remember.

Thank you.

I never made large amounts but I typically add 1 - 2 teaspoons per quart of water.

What you can do is add a small amount, shake the solution. Open the lid and wave your hand above the lid to move the air. If you get a gentle smell of sulfer your set.

DO NOT PLACE YOUR FACE OVER THE OPENING AND SNIFF!!!!!!!!!!

I'd try a tablespoon per gallon at first and see. Remember it is not so much the water/K-Meta that kills the bacteria but the fumes the soultion gives off.

I buy 2 oz bottles from the LHBS. Says on the bottle to sanitize add 2 oz to 1 gal of water. They are $1.19 a little more than if I'd buy in bulk, but nothing to remember just open pour into a gallon of water and I'm done.

I'm guessing the sodium is the same strength as potassium.
I use 3 tablespoons of k-meta per gal. Just put a airlock on it and will last for months. You can also add some to a spray bottle for spot sanitizing

Im pretty sure that 2 ozs is the same as 3 tblespoons. You are really supposed to also use citric acid withit also but I dont advise adding this to the 1 gallon along with the sulfite and instead just add it to the amount you are about to use to sanitize as it makes the sulfite come out of suspension must faster making it become much more effective which would make that 1 gallon jug use its potency much faster!
