Mould in your wall

[OlgaSikaki]

I discovered that if you want to prevent the mould to extend the only thing you have to do is add in every corner of your house a little bowl with coffee seeds. It really helps.
Also if you want to clean it, the only thing that helps is rub the area with the mould with hot water and little white vinegar. It works like magic.

Are you saying coffee beans?
Also: Charcoal briquettes (the kind people use in barbecue grills) work really well and last a long time to absorb moisture and prevent mold/mildew.
I live on the beach and the air is very moist/humid. We put bowls of 3-4 bricks in all closets, under the beds, in the back of bath and kitchen cabinets and under living room furniture.

Use Boron/Borax to inhibit mold growth and kill mold. It is good for general cleaning, and it is an effective deodorizer.
Borax also kills germs and bacteria. It is a disinfectant, biocide, insecticide, pesticide, herbicide and fungicide.

Is Boron/Borax safe?
Boron is also an important trace mineral, and when consumed in very low dosage delivers many health benefits.
