People thought that our family was unsanitary. For this reason, I often spray air fresheners, but the effect is not great, but I can't always carry a bottle of toilet spirit in my hand. So, one day, I poured a bottle of expired shampoo into the water tank of the toilet. After a few minutes, I rushed with water. The smell of the toilet was gone, and the smell of the fragrance was replaced. Since then, I have accumulated expired shampoo. When the toilet smells, I drop a few drops into the water tank and naturally find a recipe for the toilet.
