1. How to Use Bicarb Soda for Laundry

  • Hypoallergenic laundry powder: use 1 cup bicarb in place of laundry powder for an effective wash that won't irritate sensitive skin and leave your clothes fresh and soft. Alternatively add 1/2 cup to your regular wash to improve the performance of your regular washing powder/liquid for extra power or to be able to use less regular detergent.
  • Stain removal: dampen the stained fabric with cold water and rub bicarb soda into it with an old toothbrush. Leave to soak for an hour (repeat if necessary) and then wash as normal. Suitable for blood, vomit, urine, sweat, citrus juice, rust and other stains.
  • Fabric softener: bicarb washes your clothes and also works as a fabric softener. Add 1/2 cup mixed with a little water into the conditioner drawer of your washing machine. To make up a mix for later, mix two parts water, one part bicarb and one part vinegar and store in a glass jar (after it's finished fizzing) to use 1/4 cup in the fabric softener drawer of your washing machine. 
  • Cloth nappies: soak dirty nappies in bicarb and water overnight and then wash as normal. This will curb smells and remove stains and bacteria.

2. How to Use Bicarb Soda for Personal Care

  • Soothe allergic skin, sunburn, insect bites, acne and razor burn by adding 2 cups bicarb to your bath water or make a bicarb paste with a little water and smear onto affected areas. Allow to dry for 5-10 minutes to relieve itching and/or soothe skin.
  • Exfoliate skin with a paste of three parts bicarb to one part water. Use as a facial scrub and rinse with cool water.
  • Moisturise your skin while doing the dishes by adding a little bicarb soda to your washing up water.
  • Revive lifeless hair by adding 2 teaspoons of bicarb to your shampoo to help condition your hair and remove any build-up of products that may be leaving your hair feeling greasy.
  • Whiten teeth by dipping your wet toothbrush into a little bicarb and brush your teeth as normal. Do this once per week to remove teeth stains. Do not swallow and avoid doing this if you have any gum rawness/irritation.
  • Make a breath freshener with 1/2 teaspoon bicarb mixed with water to gargle (do not swallow) to kill germs and leave your mouth feeling fresh.
  • Relieve tired, sore or smelly feet by soaking in a foot bath containing 1 cup of bicarb in water - you'll be amazing how much better they feel!

    I also use bicarb in my homemade deodorant which is much more effective than any commercial product or the natural commercial product I used before I found this recipe. It contains 1 part each of bicarb and cornflour/arrowroot, mixed into 2 parts of coconut oil with essential oils (I use equal parts tea tree and lavender oils(10 drops ea. to 1/4 cup bicarb) the lavender hides the tea tree smell) It can also contain up to 2/3 part of bentonite clay which I use if I have it, but is effective without the clay. In winter it is solid and I rub my finger on the surface until a little is melted. In summer I keep a small teaspoon with the jar and stir then use what is left on the spoon.
