Bleach has a strong oxidizing action, and therefore the possibility of reducing the tissue strength and corrosion of metal products. Bleach - an unstable chemical compound quickly decomposes under the action of carbon dioxide, moisture, light, heat. Even with proper storage of bleach (in a dense wood IPT iron containers, protected against corrosion in dry and cool conditions)
