For a make-it yourself fire retardant mixture, mix 7 oz. Borax, 3 oz. boric acid, and 2 qts. warm water. Stir to dissolve completely. Either dip the fabric in the mixture or spray on to thoroughly saturate the material until it drips. This product will wash right out without damage to the fabrics so if you have to use a bedsheet for stage curtains, it won't damage them for at home use.

Thrifty Fun has been around so long that many of our pages have been reset several times. Archives are older versions of the page and the feedback that was provided then.
My brother reminded me of this tonight (he's a fireman) :)
Making children's clothing flame retardant: Mix together nine oz. 20 Mule Team Borax and four oz. boric acid in one gallon water. If the article is washable, soak in the solution after final rinsing, then dry. If the garment is not washable, spray with the solution. This solution, recommended by fire departments, may wash out of clothing and should be used after each washing or dry cleaning.

Wear gloves, keep away from children, unless you have such a small concentration in lots of water that it's no problem. Are you certain the fire dept. said to use it on children's clothes? I'd like to know. : ) (11/13/2006)

As far as toxicity, Boric Acid works as an insecticide by attacking the exoskeleton, not by interfering with the insect's chemistry. It's LD50 (the Dose which is Lethal to 50% of the test subjects) is 2,660 milligrams per kilogram of body weight (I believe this was a test in rats). For reference, aspirin has an LD50 of 1,000 and table salt has an LD50 of 3,000. There's a fact sheet at http://npic.orst.edu/factsheets/borictech.pdf. (11/29/2006)
