Mine expired in March 2020...I had it "hidden" under a laundry area sink and was using newer ones and forgot about it...
Safe to open?
Safe to pour down drain?

Maybe check your local city/county website to see if they consider it a "household hazardous waste". If it is, you should be able to find a free drop-off/recycling center where you can take it (and any other stuff you are wanting to get rid of). This is for where I live:kyphysics said:Safe to pour down drain?
Umm,... wouldn't it just end up down the drain anyway?hutchphd said:[...] Wash your deck or your white clothes. Don't just pour it down the sink! Save our planet, please.

Yes, but you would have poured one gallon down the drain. If you pour it down the drain without using it, and then buy a new bottle to use, so it ends up down the drain, you would have done the same cleaning at a cost of two gallons down the sink.strangerep said:Umm,... wouldn't it just end up down the drain anyway?

Use it as normal. It may not work as well as fresh stuff, but it probably will.kyphysics said:Mine expired in March 2020...I had it "hidden" under a laundry area sink and was using newer ones and forgot about it...

It is OK to put it down the drain 1 cup at a time in the wash so why not pour it down the drain in dilution unless you have a septic tank. Can't imagine it being considered hazardous as it is an oxidizer, right? So it is going to find some yummy turds to oxidize before it gets to the waste treatment plant.berkeman said:Maybe check your local city/county website to see if they consider it a "household hazardous waste".

About that bleach... Likely it's just as good as a new one.
Your getting a little carried away there aren't you?kyphysics said:3.) This may sound "bad," but I thought of taking it to my local library and pouring it down THEIR sink with running water if it was safe to open and pour down sinks. LOL. Figured if it damaged something, it'd be THEIR sink/pipes/etc. Who knows...maybe they'd arrest me or something.
Or, if person is equipped, actual bleach (hypochlorite) can be measured.minerva said:(In applications where you really need to have confidence that it has germ-killing potency, like in hospital labs, microbiology, or anywhere where biohazards are handled, safety regulators insist that bleach must be carefully monitored for expiry date and replaced, so that it is known to still be active to do its job.)
Did you get the same bleach? What product was it? It would be interesting to see what it was and to look at the label. Thanks.Tom.G said:Aww... come on folks! At around 7% sodium hypochlorite you would have to dump a significant amount on a fair sized surface for real problems to occur. For instance covering the bottom of a kitchen sink straight out of the container would NOT be a good idea.
About a week ago I went to use some bleach that had been sitting around for roughly a year. When opened there was NO Chlorine smell at all (yes, the cap was tight.) I dumped it down the drain, trashed the bottle, and bought a fresh bottle.
For super safety, you can take it outdoors, with it pointed away from you and the wind to your back, and open it. Then cautiously smell it. If it smells like Chlorine, use it, else discard and replace.
Been there, done that

When bleach expires, it loses its effectiveness as a disinfectant and may not be as effective at removing stains or whitening clothes. The chemical composition of the bleach may also change, making it less stable and potentially hazardous to use.
It is not recommended to use expired bleach as it may not be as effective and could potentially be harmful. It is best to dispose of expired bleach properly and use a new, unexpired bottle for cleaning and disinfecting.
Expired bleach should be disposed of properly according to local regulations. In most cases, it can be safely poured down the drain with plenty of water. However, if you are unsure, contact your local waste management facility for guidance.
No, it is not safe to mix expired bleach with other cleaning products, especially ammonia or vinegar. This can create toxic fumes that can be harmful to your health. It is important to always read and follow the instructions on cleaning products and never mix them together.
Bleach usually has a shelf life of about 6 months to 1 year. You can tell if bleach has expired by checking the expiration date on the bottle. If there is no date, you can also check the color and smell of the bleach. Expired bleach may have a yellowish tint and a strong, pungent odor. If you are unsure, it is best to err on the side of caution and dispose of the bleach.
