Do not use vinegar and baking soda at the same time as they simply cancel each other out. One is an acid and the other is a base so mixing them results in a chemical reaction that reduces the cleaning ability of these chemicals. Vinegar is great for removing smells and getting your nets a bright white color once again. They will also remove mildew and mold. Baking soda is excellent at removing mildew and mold, can remove bad odors and will help whiten your curtains. [2] X Research source

Vinegar should not be used on curtains that are made from linen because it will burn them. Most modern inexpensive net curtains are made from polyester but if you are unsure whether your curtains have linen then you should skip this step.

You can also use any commercial stain remover to apply to stains. Some net curtain manufacturers may recommend a certain stain remover to use. [3] X Research source

If you curtains are particularly delicate then you may have to hand wash them. Delicate curtains include those that are antiques or look like they might fall apart if washed. This also includes net curtains made from wool or silk, which should again be hand washed. Hand wash by placing in a basin of cool water with a little laundry detergent or dishwashing soap. Gently agitate the water to allow the soap to penetrate fully. Rather than squeezing out the delicate material, simply hang it up outside while wet and allow it to dry. This will prevent major wrinkles. Silk cannot be hung up to dry or else it will yellow. Rather roll the net curtain in a towel to remove excess water and then iron on low heat to dry.

If you do not have a special detergent then that is fine. Because you have pretreated and pre-soaked your curtains, any stains should be removed already and your choice of detergent should not have a major impact.

If you have a top-loader then you should add your washing powder after some water has filled into the machine. If you wish, you can add 2–3 tablespoons (29. 6–44. 4 ml) of baking soda to the wash cycle to help the machine.

Remove the curtains before spinning, or put them on very low spin so that they do not wrinkle. Do not use vinegar with linen curtains or else it can burn them.

It is difficult to iron net curtains without damaging them so try not to allow wrinkles to appear in the first place by hanging them to dry while still wet or damp.
