Discover the easiest way to cut grandma's yellow soap into cubes
Grandma's yellow soap, also know as potassium soft soap, is a fully biodegradable soap that contains potassium salt with fatty acids, vegetable oil, glycerin and water. This soap, sold under the names of several famous brands in many countries, is used both for household chores and as a pesticide in agriculture, making it an effective alternative to many less environmentally friendly products.
Depending on the use you want to make of it, you have to consider which brand to use: in fact, in the stores, it is very easy to find one that contains coconut oil - which is a substance with germicidal properties, making it perfect for doing laundry and also as a degreaser spray. But if you don't need this ingredient, look for the simpler versions. Either way, potassium soft soap always comes with a sticky consistency that makes it a little annoying to use, but is also still tough enough to prevent it from being cut easily with a knife.
Typically, when you use this soap, you usually need only a small portion, a bit like with Marseille soap sticks that last for months and months. Given this, it is much more convenient to find a few minutes to divide up each stick you bought into single-portion cubes.
We say "a few minutes" because using the corret method it takes very little effort to cut it up. If you use a knife, in fact, it could be a bit difficult, but if you use a simple sewing thread, it will become child's play.
You can see how simple this method is in this video from the TikTok account of @estela_tips: just choose a good quality, strong thread (a nylon one should work well, as long as it's thin) and then use it as you would a knife - cutting parallel lines at distances that are as equal as possible to each other over the entire length, height and depth of the block. It is really satisfying to see how the thread passes through this semi-transparent block and slowly creates the cubes!
Once you have prepared your cubes you can work them just with your hands, so that your body heat allows you to turn them into balls, or even choose to leave them as they are.
How should you store the cubes? Put them in an airtight container (jars or lunch boxes, for example), or maybe use several smaller containers to keep ready in the rooms where you need the soap. In any case, you will need to choose places that are not too close to heat sources or exposed to direct sunlight, otherwise the cubes will end up fusing together again.
Do you use grandma's yellow soap often (if ever)?
