The ingredients needed to prepare the liquid laundry detergent you will need for a year’s worth of laundry are:
Marseille soap flakes, 60 grams (average cost, about 0.40 cents)
sodium percarbonate, 15 grams (average cost 0.15 cents)
bicarbonate, 30 grams, (average cost 0.10 cents)
essential oil, a few drops (about 0.05 cents).
1 liter of hot water
1 liter of cold water
You must first heat a liter of water. Inside, the Marseille soap flakes must be incorporated. The fries should be well mixed.

Once the fire is out, pour in the percarbonate of soda then the bicarbonate. Then you can proceed to mix everything using a blender. The goal is to make the mixture as homogeneous as possible.
Then the mixture should be cooled and allowed to sit for about a full day. At this point the detergent should have become very compacted, but this is normal. The next step is to mix everything by adding a liter of cold water. Once again, the goal is to make the mixture homogeneous and smooth.
You will need pots, those of classic liquid detergents previously rinsed and dried are fine but also simple plastic bottles. If you prefer, you can choose a glass jar. A few drops of essential oil of your choice should be added to the detergent. It will be used to perfume the linen. Lavender and lemon are an example.

For a low cost, you will obtain a liquid detergent capable of whitening, disinfecting and removing stains from your laundry. These properties are given to it by bicarbonate which is a natural and biodegradable product. Additionally, it can also act as a fabric softener and deodorant.

Sodium percarbonate, on the other hand, disinfects and stains. Marseille soap, for its part, is a biodegradable and anti-allergic product that cleans gently.
