The cleaning process itself washes away most bacteria. Moreover, hot water kills most microorganisms in the water.
You may choose to use natural alternatives:
1. Straight 5 percent solution of vinegar—such as the ones you can buy in the supermarket. Reports have proven that it kills 99% of bacteria, 82% of mold, and 80% of germs.
2. 3% hydrogen peroxide (the same strength found at the drug store for gargling or disinfection).
3. Combine the first two formulations, and use it one after the other. It does not really matter which one is used first. For best results, apply one immediately after the other.
How to apply each natural alternative:
Spray it on areas that are usually loaded with bacteria like the armpits, the neckline, in sweaty areas, in underwear, etc. Make sure that you test the spray in an inconspicuous area of clothing to ensure colorfastness. The hydrogen peroxide is a very effective natural bleach and can bleed colours, so be careful.
