Sniff it. Go round the shops and sniff it. Some 2 litre bottles smell of nothing at all. 1 litre bottles range from a faint waft of very distant bathroom to what we might expect though I'm not sure. Fresh thick bleach aroma should go up the nose like wire wool and leave us gasping.
The bathroom here is tiny with no opening window. Time was (a year ago....?? hmmm, I didn't keep a bleach diary), I had to be careful chucking the bleach about or I'd be asphyxiated. For quite a while (since before The Virus) I can splash the bleach without a care.
Reading up, I discover bleach expires after six months on the shelf, some suggest maybe twelve months. Surprise! Bleach is such a mean, tough, fire breathing baby, who'd have thought merely being left on the shelf would flatten it.
What we need is clear date labelling on bleach bottles as seen on food and medicine. Before that, supermarkets could weigh in and be helpful and put up notices saying the XXX123 code on the bottle means 'Expires 13th April 2020'. (Dull work of little interest for supermarkets but wildly exciting (well; drably vital) for the helpless customer).
Are we being deliberately taken to the cleaners with cleaning fluid? Probably not, just ignorance all down the supply chain to the shopping trolley:
"Running low on bleach Fred."
"It's alright. There're two pallets at the back of the warehouse. Load 'em up."
(They've been sitting there for three years but who knew?)
We need to clearly see the expiry date. Otherwise, either I'm having delusions of paranoia or we're strolling into a disinfecting battle with The Virus armed with lightly scented water.
