Thank you all for replying, I haven’t use Diatomeceous yet but maybe I’ll give it a try. “1001 uses and properties of baking soda” by the health publishing company, I don’t have the book yet but I’ll try to get it next week if I have time.
I’ve already used Bleach as disinfectant before but I don’t really like it. It has a very strong odor and its power degrades with age and exposure to heat or light, that’s why I’m looking for effective ways ones, anyway thanks for the suggestion.
