Window Cleaner

1/4 cup vinegar

2 cups of water in a spray bottle. Shake to blend.

OR

Equal parts vinegar and water in a spray bottle.
Or, 1/2 lemon juice and 2 cups water in a spray bottle

Here's the skinny on homemade window cleaner. You may find that even straight vinegar is leaving streaks on your windows. Here's why: some commercial products contain wax. After years of use, they leave 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 will remove the buildup. I love Seventh Generation dish soap. You can get a free & clear version.

Commercial Window Cleaner Toxicity:
Most commercial window cleaners contain ammonia. Ammonia fumes can also react with nitrates in the environment to form ammonium nitrate particles, which can linger in the home in dust, carpets, curtains and upholstery. It is extremely toxic when inhaled in concentrated vapors and repeated exposure may lead to bronchitis and pneumonia. It can cause chemical burns, cataracts and corneal damage, and has been shown to produce skin cancer. Disruptions to the ecosystem can result, with toxic effects to plants, animals and fish. The EPA lists ammonia as a toxic chemical on its Community Right-to-Know list. Ammonia ranks among the highest of all chemicals released into American waters.
