They are creating some confusion on bleach with the new marketing names. What we do need to look at is not the name but what is in the bottle! Look for the percentage of chlorine as some are coming up different than the old standard 6% .
And we don't want any of the scents or colors as they are just prone to being more expensive as well as potential for adding "wildcards" that we don't need.
Yes, the Wal-mart "Great Value" brand is as good as any but it does pay to check the label for concentration. Not that the amount is really very critical as we are guessing at how much gunk we need cleaned but then I like to get the same amount of chlorine each time as that is what I pay for, not the water they mix it with.
One way to help bleach last longer is watching where you store it. If the lid is not tight, it will lose all the chlorine and just be a jug of water. Also watch the temp and keep it out of the sunlight. When folks worry about how to clear the bleach off things like rocks and wood we might use it on, they forget how easy it is to ruin a jug of it. The good stuff will gas off really quick if you don't store it really tight.
