Having been inspired by my good friend J., who is making her own (super-easy-to-make) homemade powdered laundry detergent (which I am planning to try next week), I offer the following two recipes which I have tried this week. Voila!
2 cups rubbing alcohol
1/2 cup ammonia
1 teaspoon Joy dishwashing soap
Blue food coloring, optional
Put above in gallon container and add water to make one gallon. I just made this ten minutes ago and haven't had time to try it yet, but the reviewers on the original recipe all rave about it.
Homemade Dishwasher Detergent
Into a 32-ounce container place:
1/2 cup borax (laundry aisle)
1/2 cup washing soda (laundry aisle)
1/4 cup kosher salt (with the salt!)
1/4 cup citric acid (buy from brewery, herb shop, or health food store - I get mine in the bulk herbs at Sprouts)
Shake well. Ignore any clumps. Use 1 Tbsp. per load. Works beautifully!
Can also fill rinse compartment with white vinegar. I haven't figured out how this works yet, so I haven't tried this.
