I tested it on the mildew that tends to grow between the tiles in my shower.I usually have it cleaned with detergent and white vinegar but it grows back a few weeks later.
I decided to treat it with grapeseed oil and poured a few drops on the joints, doing that twice a week for 2 weeks and letting it stay several hours in a row.
It's been 2 months, and there is no regrowth.
Encouraged by these results, I tried it to get rid of an invasion of drain flies in my kitchen.
I cannot use chlorine or chemical sprays because the smell triggers my allergies. I tried peroxyde, with not much result.
This time, after using it 3 times, the drain flies are gone.
This stuff is really powerful. It's antibacterial, antifungal,antibugs, and it is not supposed to kill the good intestinal flora, like regular antibiotics do.
I will never use antibiotics again.
