Ok, today is the day to make grape jelly. Measured out the juice,
washed the jars, and then washed the jar I had stored the juice in.
The cap was white plastic, and of course had grape stains on it. My
usual method is to scrub it with a little baking soda, which did a
pretty good job, but left a few blue stains that would not scrub
out.

I rinsed the cap well, and then sprayed it with the 10% bleach
solution I use for cleaning. The bleach in the cap turned an orangey
brown! I've used the same method on the white counters that came with
the kitchen (formica), and any number of other grape-stained items and
never had this occur.

Any chemists out there with an explanation?

Just curious.

I'm just curious too. 10% is VERY STRONG. Why do you use it that
strong?
I've been in the janitorial business on and off for 30+ years, and I
use bleach often, but not that strong.

Public health often recommends a freshly prepared 10% solution for
environmental surface sanitizing, Bryan. Of course you wouldn't want to use
it on fabrics or other surfaces that react poorly with bleach.

I imagine you probably have access to bleach-free disinfectant chemicals
which also do a great job.

I see that:
http://ncchildcare.dhhs.state.nc.us/...fact_sheet.pdf
We use the 1/4 cup/gal, and I can't think of a home use where anyone
would want anything stronger unless your sewer backed up. For regular
kitchen/bathroom use, that seems like plenty.
For sanitizing the stuff in the child care and preschool rooms, the
standard is 200ppm, which is about 4x more dilute than the 1/4 cup
above.

Those quaternary ammonium chloride disinfectants--which is what Lysol
contains--are SO expensive that we almost never use them, and I don't
think they make phenol disinfectants anymore. Bleach is very cheap.

Does your health dept want you to use bleach that strong (10%)?

Only for visible contaminents like blood, vomit, feces, urine, etc.

What's funny is that urine is sterile. Icky maybe, but sterile.

Yup. The problem is it quickly grows bacteria once it leaves the body.

A 10% solution works as well as using 100% bleach. This is what we were
taught in college microbiology class.

Usually...not always.

Math-impaired moment. It's 1:31 dilution of the stuff bought at
the grocery store, so closer to 3%.

Urine is sterile when it's in your body. Once it comes out, it starts
to grow all sorts of lovely bacteria

Probably lot easier on the mop heads than bleach. Especially the way
one of my coworkers over-uses it.

Where do you get it for $25 a gallon?

There may be some confusion here. What do you mean by 10%?

Laundry bleach runs from 3% to 6% sodium hypochlorite. You can't make a 10%
solution from a 6% solution. If you mean 1 part commercial strength bleach
to 10 parts water, this is really something different. You can also buy
sodium hypochlorite in stronger solutions for industrial use..

The label on my generic bleach says to use 3/4 cup of bleach with one gallon
of water. The Clorox company web site agrees.
