There was a notice on the back of this weeks Wegmans circular that caught my eye. Bleach is now going to be be sold (well, Clorox and Wegmans store brand at the very least) in a more concentrated form.
So if you sanitize with it, you can scale back the amount you use. The rule of thumb for 1 tablespoon per gallon can now be scaled back to 2 teaspoons per gallon.
A cursory Google search didn't find anything talking about it, so I snapped a photo of the ad and attached it.
