Is bleach weaker today?
|
|
|
| Has anyone else observed that laundry bleach seems to
be weaker than it was 20 years ago?

Don't know about that, Donna, but it still smells as bad.

It has a limited shelf life. It used to be 5.25% because that
concentration had a good shelf life. Now it's usually 6%. I think
manufacturing had improved so that the stronger concentration had
an adequate shelf life, and it saved on shipping weight.
My last bottle was a discount brand. In time it got very weak. My
new bottle, another discount brand, is much more potent, but I just
noticed the concentration is not stated on the label. That
convinced me to buy name-brand bleach in the future.

mine is less than 5% sodium hypochlorite and it's a top brand but it
is a thick bleach.
I can't recall using the thick one twenty years ago

| awhile back I purchased bleach at Costco. They came in a set of 2 gallon
plastic containers. My utility room is small and lacks much space so I
poured some of the bleach from the gallon bottle into a smaller =BD gal
bleach bottle. That way I could store on the floor next to the washing
machine. Well I do not use bleach all that often. When I finally picked
up that small bottle the vinyl floor is totally stained yellow as if the
bleach had leached onto the floor. Luckily it not an area in direct
vision

I have had bleach kept a long (really long) time sort of eat through the
plastic bottle a little bit. Now when I store it in the cupboard I put the
bottle into a larger plastic bowl---sort of as a coaster. Now, having heard
your experience, I think I'll start storing it in the garage.
