Although most commercially produced child's fabric costumes and pyjamas are fire retardant, homemade garments are not. But you can make a fire-retardant solution easily and inexpensively, and temporarily treat your child's clothing or costumes. This is the formula often recommended by fire brigades for treating garments. You'll need to reapply the solution after you wash or clean the clothing.

Skill level:

Things you need

  • Large bucket or pail
  • Gallon of hot water
  • Borax
  • Boric acid
  • Long-handled spoon

  1. 1

    Machine wash and rinse the garments to be treated as you usually do. Do not dry them.

  2. 2

    Pour a gallon of hot water into a large bucket or pail.

  3. 3

    Add 255 or 284g of borax to the water, stirring very well with a long-handled spoon to dissolve it. Stir in 117 or 147ml of boric acid. Mix thoroughly to dissolve.

  4. 4

    Soak the garments in the bucket of fire-retardant solution. Squeeze out as much excess liquid by hand as possible. Tumble dry the clothing as you usually do.

Tips and warnings

  • If the garment should not be washed or immersed in liquids, you can put the solution in a plastic spray bottle to spritz it onto the clothing.
  • Don't forget to retreat fabrics with the solution after laundering. Washing or cleaning removes the fire-retardant properties.
