It's usually on the side of the box/bottle, and formatted as a Julian date. For example 17-085 would be the 85th day of 2017. There are a number of charts available online that will let you determine the exact date based on the Julian date.
17090 = 90th day of 2017How do you tell the 'manufacture" date on bleach?
Leslie's by me regularly runs coupons. $7.98 to refill two 2.5g jugs. That's 5 gallons of 10% for roughly $8. Works out to $1.60 a gallon.
They also do a punch card. Each jug refilled earns a punch. Get 10 and get a free refill. If you go on Wednesday you get double punches. If you always fill up on Wednesday, you can get the effective cost down to $1.33 per gallon!

Nice. My Leslie's tried to argue with me about using liquid chlorine. I buy it elsewhere.![]()
This is the best deal near me. $1.88 per gallon.

They are also running 20 Blume acid for $2.99 per gallon.
That's a great deal. Been doing 31.45% Baume acid from Home Depot and Walmart Pool Essentials 10% chlorine for $3.46. Never been to an Atwood's.

Can I use acid instead of chlorine? Sorry - late to the party here!
Again this year Ocean State Job Lot is selling 128 oz jugs of 12.5% chlorine for $2.99.
I have seen where the cases are marked with the date code and the jugs inside the case are not marked and also where the cases are not marked put yhe jugs in them are. I buy cases at a time and check for the code on the boxes, if there is no code on the box, then i open them and check the jugs for the code. The case I bought last week was Austin Pool Tech Shock and the date code was marked on the box. It was marked with 17088MA, which is the 88th day of 2017 or March 29. I believe that the MA means that the product was manufactured in Austin's Massachusetts plant.I couldn't find a date code anywhere on the jugs at ocean sate. Have you found it / am I just an idiot?
