Before you wash them, how about you sanitize them? It's simple: let them soak in a very hot basin, containing about ten drops of essential oil of tea tree, Scots pine or even ravintsara: all three are unstoppable against microbes, and you will avoid having to bleach when you wash.
MY NATURAL AND NON-POLLUTING RECIPES FOR MY KITCHEN
Cleaning without polluting is actually much easier than it seems! And once you've tried it, you're always convinced. Why is that? Because the products are effective, economical, and smell good... In short, they're not only really ‘clean’, but they're also great assets!
Mix 2 tablespoons of white vinegar and 2 drops of lemon essence, clean with a damp cloth soaked in the mixture. Then put some bicarbonate of soda in a bowl to avoid odours.
If the sink or washbasin drains back up unpleasantly, pour 2 to 3 drops of tea tree essential oil or lemongrass into half a glass of bicarbonate of soda, top up with very hot water and run it down the drain.
Wait for 2 to 3 hours, rinse with white vinegar then, 15 minutes later, abundantly with hot water. Radical! Does it stay clogged? Try the mixture of white vinegar + bicarbonate of soda + salt (mix well before pouring), leave it to work and rinse abundantly with boiling water.
To boost your household product (preferably ecological!) and to make it more active against microbes, add 50 to 60 drops of tea tree, Siberian fir or peppermint essential oil per 100 ml of product.
