Homeowner Forum / Cleaning / January 2006Is bleach weaker today?
Has anyone else observed that laundry bleach seems to be weaker than it was 20 years ago?

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. >> Has anyone else observed that laundry bleach seems to >> be weaker than it was 20 years ago?

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 ½ 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.

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. Donna |
