cleaning mirrors

[wjcalderon]

The best option I've found for cleaning mirrors, windows, glass-topped tables, etc., is a microfiber cloth. 
You can buy a package of 2 that are specifially for glass at Wal-Mart for $1.97.
Just wet one with plain water, wring out thoroughly and wipe.  Give it a minute to dry.  No streaks - no chemicals - put the cloths in the washer and dryer and you're ready to go again.
They're great for stainless steel appliances, granite countertops, the list is endless!

The Best Window Cleaner

Around Earth Day 1990, every newspaper in the country (or so it seemed) offered recipes for non-toxic cleaning with the basics we all have in our kitchen cupboards, and the recipe for windows was invariably just plain vinegar and water with the option of drying the windows with old newspapers.

People by the thousands tried this and swore off cleaning with homemade recipes for good because the formula left streaks on their windows.

Unfortunately, the commercial products they had used for so many years had left a wax buildup and vinegar alone wouldn't do the job of removing the residue. Adding dab of dish soap to the vinegar and water would have removed the buildup.

The Best Window Cleaner
Make a great all-purpose window cleaner by combining 1/4 cup vinegar, 1/2 teaspoon liquid soap or detergent, and 2 cups of water in a spray bottle. Combine in a spray bottle. Shake to blend.

I KNOW this sounds really simple but it did win over my very sceptical DH.  Mix 1cup of water, 1/4 cup of white vinegar and 1 tsp liguid dish washing detergent in an old spray bottle.  I find using old newspapers instead of paper towels works best.  This will clean most windows including car windsheilds.  Hope it works for you.

I have a spray bottle with a mixture of 50% vinegar and 50% water.  It really keeps my mirrors clean.

Assuming you've tried everybody's favorite Vinegar,
you may need to "scrape" it one good time with a
single edge razor. I had to do this to get the film
off glass shower doors when we bought our house.
Then I went over it good with the vinegar and put a
light coating of car wax. Do not do any of this if
the mirrors are not real glass. Another miracle liquid
is real acetone. CAUTION: Acetone can "craze" many
surfaces, so be especially careful when using it. I've
used it to remove painted on lettering from a salad
dressing jar. It's that strong, so be careful. As a
last resort, you can replace the mirror, but it's not
a very frugal suggestion.
