DIY Window Cleaner {as good as Windex}

Seriously, I'm starting to find it amazing how I've been paying such a huge mark-up on products that I can very easily make myself!  Windex is another example.  I made my own in under 3 minutes and saved a bundle.  Here's how...

What you need:
1/8 C White Ammonia
1/4 C Isopropyl Rubbing Alcohol
1 drop of dish detergent

Mix ingredients, pour into empty spray bottle, fill the rest of the way up with water. And done!

The Cost:
20 cents per bottle
Windex = $2.87 per bottle

What I purchased:
ammonia $1
rubbing alcohol $1
dish detergent; on hand
