I can’t undo…

Childproof caps are also disabledproof.

Can you not buy ordinary bottle caps for things like bleach bottles instead of the child-proof ones? Then you only need to open the child-proof one once, take it off and put one you can open on instead.

I check pill bottles before leaving the chemist, and get the young women behind the counter to open bottles for me if I cannot do so myself.

There are various gadgets made for opening screw top jars etc. with weak hands. Check Amazon or the like, or ask your district nurse where you can get suitable gadgets. They do exist and make life much easier.

The mother of a relative of mine had trouble seeing and also arthritic hands. She used to lie in wait at her garden gate for someone to walk past. She would say "Excuse me, I don't see too well. Could you tell me whether this (shows bottle) is red wine or white?" Once she had an answer, she would ask " . . and would you be so kind as to open it for me? and produce a corkscrew.

I have to drink water from bottles I cannot open, but I have a pair of scissors with gagged edges just before the scissor blades. With those metal bits my bottles open easily and wonder why I had never noticed this facility on my kitchen scissors before now!

I can no longer manage all of the aforementioned plus the stupid little bit of silver foil on the large size fairy liquid bottles!

Half the gadgets I’ve tried are less than useless

I changed to a brand of hair products where the shampoo is in a black bottle and the conditioner is in a white bottle because of the difficulty of reading in the shower 🤣 I noticed some brands have one of the products upside down - maybe more brands should follow suit… then I can go back to my favourite.
@hetty58 I understand your daughter’s confusion. Dove is one of the hardest brands to ‘sort’ I’ve used body wash as hand cream and vice versa more than once 🙄

I’ve now put together a kit in my kitchen drawer - nut crackers, adjustable spanner, pliers, crocodile thingy and a Stanley knife for cutting those wretched top down bottles in half so I can get at the last bits. I also have a small fine toothed saw for the same job, it has a particularly name which I new a minute ago but not now!

It’s a hacksaw! I’ve also added a pair of nail scissors and one of those blades that you roll along for getting in to film wrapping. Hoping that having everything to hand, in one place, will reduce my frustration.

I have recently come to the conclusion that almost everything is designed for super-fit 25 year old men of at least average height and with perfect sight and hearing. Bottle tops, medicine containers of various sorts, tiny writing on instructions, background music levels in films, seat belts ( women are far more likely to be seriously injured in an accident) etc etc .......
Think I've digressed a bit 🙄

I find that working the tines of a fork under the edge of tops of vacuum sealed jars releases the vacuum and makes them easier to open. My personal hate is reserved for those non prescription medications that can be used to make dangerous drugs and in the US are now only available in tiny quantities in impossible to open blister packs! As though that will stop a dedicated drug user!

To save bending the tines of my forks, I use an old-style can punch, as in the photo. I have several, left over from pre-ringpull days. The rounded end inserted under the edge of the lid and levered loosens the seal on most jamjars etc, and the pointed end gets under the edge on stubborn ones. I use the can punch on evaporated milk tins and other tins of liquid too. If you have chucked your old ones out, I've just looked on Amazon, and you can still buy them for £1.99. www.amazon.co.uk/Dexam-Traditional-Nickel-Plated-Bottle?tag=gransnetforum-21
