Another very effective method, not only for these items, but also for appliances, countertops, doors and furniture, is to use hydrogen peroxide. Again, it should be applied neat and left on for an hour. At the end of the installation, simply rinse thoroughly and dry well. Very simple, right?
But let’s come to the real ace up the sleeve of any housewife who plans to renew yellowed plastic: toothpaste! Although it may seem unthinkable, it will make a difference, provided you use the whitening version.
Use an old, used toothbrush: not only is it easy to handle, but it can also reach places that would otherwise be difficult to reach. Spread a little toothpaste, rub it over the entire surface, insisting if necessary. You should make circular movements exactly like you do when brushing your teeth. Leave on for around twenty minutes, then dry with a soft, slightly damp cloth to remove the excess.
If a first layer is not enough, repeat adding the tip of a teaspoon of baking soda. This way you will enhance the whitening power of the toothpaste. The slightly abrasive action of baking soda will penetrate between the polymers and turn your objects snow white.
Easy, isn’t it?
