I couldn't find it, so maybe I put it somewhere else... anyway, this is the all purpose cleaner I use most of the time. It sometimes takes a stronger version, but this one does almost everything and it's a lot cheaper than commercial cleaners.
1/4 cup of ammonia (lemon scented makes it smell nice)
1 teaspoon of good liquid dish detergent
3/4 of a pint of water.
Mix with a spoon - don't shake to mix because it will suds a lot. I keep mine in a spray bottle.
And if you find it already posted on this blog, let me know!
