I went to the south of Brazil, I tried yerba mate and I loved it! I bought a gourd and was enjoying it very much, but I left the yerba mate inside the gourd for a few days and the gourd created mold, and the taste is not the same now. What do I do? Thank you, Alessandra.
Some people use baking soda to clean the gourd, this is an option. There is also another fantastic product to clean and renew the gourd, it is called h2o2 = hydrogen peroxide!
H2o2 is simply water with an extra particle of oxygen. It is a powerful oxidant, eliminates fungi and bacteria. H2o2 can be used in house cleaning, commercial cleaning and for hospital disinfection. H2o2 has no taste, no color and no smell.
To recover your gourd, you have to thoroughly clean the gourd first with soft sponge and water. Then you add hydrogen peroxide to the top and let it sit for a few hours. Do not use detergents, soap or anything else that will penetrate the gourd and leave it with a bad taste.
You will notice that the interior will become clearer. The gourd will not turn white like when you bought it. It is normal for the gourd to be dyed by the color of the yerba mate. My gourd, which was already very dark inside and with patches of mold, became clean and clearer. You can repeat this process as many times as you feel necessary or when you start to feel some unpleasant odor.
Never put the gourd upside down, and most importantly, never leave the gourd upside down while it is moist. That’s what causes mold! It is advisable to let the gourd dry in the sun before storing in the closet.
Important: Use h2o2 for home use in the right concentration, without perfumes or any other additive, or your gourd may look worse than before!
