1- Introduce moist yerba inside the gourd (cover the mate completely). You can use wet yerba from another mate because it has less dust, but it is also possible to do it with new yerba too.
2- Introduce warm water or mate temperature water (158 to 176 ° F). This helps to disinfect and remove the dust.
3- Let it sit for 24 hours.
4- Remove the yerba with a spoon.
5- Scrape the skin to remove the membranes of the gourd.
6- Wipe with a napkin to remove the moisture from the mate.
7- Let the mate rest outdoors (or wherever there is fresh air).
8- Repeat these steps after a few minutes.
9- It is advisable to repeat this process 2-4 more times.
