I had looked it up. It has a lot of ingredients. I don't know which
ones make it clean ink better and which make it less good.

I don't know about that. I think maybe "what you mean" is that it's not
an ingredient, or an important one, in the cleaners that are advertised,
or even the ones that are sold. But ammonia itself I had no trouble
finding, 2 quarts for 2 dollars at one supermarket, and a little over 4
dollars at another. Food Lion and Maryland Giant.
I noticed a big difference in the price of windex too. The Giant was a
lot more.
Food Lion otoh, you may recall "In November 1992, two ABC News producers
obtained jobs at Food Lion grocery stores in North and South Carolina by
submitting applications with false references, misrepresenting their
educational and employment experiences on their résumés and omitting
their current employment with the network. ABC broadcasted a report on
“PrimeTime Live” alleging that Food Lion’s meat department at those
stores required employees to engage in unsafe, unhealthy or illegal
practices, including selling old meat that was washed with bleach to
kill odor, [and then dying it red so it looks nice, Micky] selling
cheese that had been gnawed by rats and working off the time clock."

A little after that time, I bought chicken from them and when I got
home, it smelled bad, the same day. Only time in my life. So for 20
years I haven't bought meat from them, but I relented last June and I
see that they are now about 40% cheaper than 2 or 3 other supermarkets
and I've seen them mark meat down when there are still 3 days left
before the sell-by date, which Food Lion itself determined. Is this
really the result of what hhappened in 1992? Hard to believe.

The company responded by suing ABC for fraud, claiming that the ABC
employees misrepresented themselves; for trespassing, because the ABC
employees came on to Food Lion property without permission; and for
breach of duty of loyalty, because the ABC employees videotaped
nonpublic areas of the store and revealed internal company information.
During the court battles between Food Lion and ABC, over 40 hours of
unused footage were released that helped Food Lion's case. In the unused
footage, two undercover producers are seen trying to encourage
violations of company policy; however, employees resisted and correctly
followed sanitary practices.[43]
Food Lion was awarded US$5.5 million by a jury in 1997. The award was
later reduced by a judge to $316,000. The verdict was then largely
overturned by the U.S. Court of Appeals Fourth Circuit in Richmond,
Virginia. According to the court: even though ABC was wrong to do what
they had done, Food Lion was not suing for defamation, but rather for
tort as a way to get around the strict First Amendment standards for
defamation. Food Lion did this because the company was not contesting
the truth of anything ABC reported in the broadcast.[44] However, the
appellate court upheld the finding that the producers involved breached
their duty of loyalty as employees to Food Lion, and had trespassed,
awarding a nominal $2 fine.[45]
I'm glad to hear it. I think lying to get a job in a place that is
painting the meat red is okay. (Out of context, this would say
"painting the meat red is okay.)
Well that is expensive but try this:

To make a great mirror and window cleaner, mix 1/2 cup ammonia, 2 cups
isopropyl rubbing alcohol, 1 tsp. Liquid dish detergent, 3-1/4 quarts of
water.

And one of the pages above says varnish too.

Okay.
