I had been using a vinegar-based all-purpose cleaner that I do still use, but I do really like this one so far, too.
Dishy Wishy Washer All Purpose Cleaner
liquid hand-dishwashing detergent (recommended Palmolive in book... I used Meijer Naturals)
Use 1 teaspoon liquid hand dishwashing detergent for an 8-ounce spray bottle of water, or 1 Tablespoon of detergent for a 16-ounce bottle, or 2-3 squirts of detergent for a bucket of warm water.
Its important to dilute the liquid detergent properly. Making lots of suds means making lots of work rinsing. If you do end up with too much detergent, you can remove the residue with a scented vinegar rinse.
Cost comparison from book - $4.35 (Fantastik) vs. $0.35 (Dishy Wishy Washer). Savings of $4.00 per bottle
