In what quantities?  As for the baking soda, we will need three tablespoons, to pour directly into the drum of the washing machine or into the detergent drawer before starting a wash

With white vinegar, you will need three or four tablespoons. It will be excellent for restoring elasticity to the fibers of our laundry, not just towels. To reduce its intense smell, we can also add four or five drops of lemon essence to the washing machine.

The same amount applies to citric acid, which acts as an excellent softener. In terms of weight, the ideal measure of citric acid to pour into the washing machine is 150 grams mixed with a liter of water in which to dissolve it. Or you can still use a few spoons of liquid Marseille soap.
