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. -- Dave www.davebbq.com

Are you talking about 10% of the already diluted retail concentration, or 10% overall final concentration?

I see that: http://ncchildcare.dhhs.state.nc.us/pdf_forms/bleach_solution_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.

I buy Professional Amphyl (a dual Phnolic product) made by Reckitt Benckiser (makers of Lysol) in bulk gallon containers. It comes at 100:1 concentration. Costs about $25 for a gallon, and at that concentration it lasts forever. Best thing about it is that it's also recommended for laundry, while quaternary ammonium chloride is not.

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.

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.

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..
