Step 3. Grease the mold with vegetable oil or non-stick spray
Step 4. Pour your favorite liquid (milk, water, tea, etc.)

Step 5. Add the grated soap while continuing to mix slowly
Step 6. Reduce the heat as the mixture should simmer slightly
Step 7. Stir slowly (but not constantly) until the grated soap is liquid
Step 8. Add additives if you prefer

Step 9. Immediately pour the mixture into the mold, then cover it with cling film
Step 10. After 24 hours, remove the foil and place the mold in a dry, draft-free environment for 3 to 4 weeks
The bar of soap will be ready to use as soon as it has dried and solidified. It will look like a completely new bar of soap.
- Here is another very simple method to reuse the old bars of soap: chop and insert the pieces of soap in a sponge; every time you wet it, it will produce a lot of foam and you can easily use the soap trapped inside.
- You can let the soap pieces soak until they become soft and malleable. At that point, squeeze and squeeze them with your hands to blend them into one piece. Let this new "bar of soap" solidify before using it.
- If you want to reuse leftover pieces of soap, soften them with water and then stick them to the new bar. Wait for the soap to solidify before using the new bar of soap. At that point, they will no longer come off.
