Will the bottles hold up with full strength household bleach?

I haven't tried bleach but they are very sturdy and the papers that came with them say they are common chemical safe.

Yes. I use these bottles for that very purpose. I soak my lemon rinds in vinegar, then strain it into the bottle.

I've only used them with normal 750 ml bottles. They might be strong enough, but I cannot answer directly.

Yes, they are very secure. I have filled the bottles with water and with fractionated coconut oil and the caps hold tight. These are fantastic.

Bonnie. This product contains a chemical (chemicals do not really have such expiration dates like food..a bottle of bleach will still be functional years later, and the same is true for the active ingredient here...5% mnxdl)...should last decades..

I think putting them in the dishwasher would probably be a bad idea, due to the heat of the water. You might try using a paste of baking soda and water, and scrub them with an old toothbrush. Other than that, soaking in a mild detergent and water overnight could help. I'm afraid bleach would have a bad effect on the plastic, causing deterioration over time. Just my opinion! I haven't tried any of this on this item in particular.

I've had these things clean stuff that bleach couldn't. Different technologies. I would definitely try them.

Yes it is. I mix up my homemade stain remover for laundry in these bottles. No problem with them :)

My answer would be yes. I use them tp wipe the kitchen counter while wet and they hold together. I also tried soaking one and then holding it by the edges with an apple in the middle. It held up well.

The bottles are plastic, and the lot come well & compactly packaged. I can't imagine you'd have any problems.

These bottles are very thin walled. The color comes off pretty easy and they dent incredibly easy. I used hose clamps to secure two of them onto a rack on a dirt bike to carry fuel. They got the job done but are pretty beat up. If you're using them as water bottles in a backpack they will probably work perfect for that. I see my post is conflicting with the other post; so I'd like to add this edit. They are good bottles the coating seems strong, just depends on what you use them for.

They will give way fairly easily until they are at their maximum opening (4 1/4" tip to tip). Fine for 12 oz cans and 1/2 L plastic bottles. I would not recommend using with a Big Gulp.

I believe so. Like others have said, the bottles look slightly different- there is no black writing on them, but there is clear indentations with "Medela" and the ounce/ mL mark lines. They are great. I've now had them for probably 8 months, use them every day and they have held up well through the freezer and dishwasher. And no leaks if they fall over.

I have not used them with a bleach solution. Can't see why they would not be ok....nothing in the description suggested NOT using them with bleach.

If you have a good wash routine you shouldn't have to bleach them. Bleach can be used, however if used to much it can break down the pul over time.

I don't think so. I tried to use bleach with it the second time I used it and I wouldn't say it's very durable.

I believe they are plenty strong enough. I use them on the 64oz and 40oz Hydro Flasks....using them daily for over one year.
