Product Overview
Wonder Foods Colloidal Silver 500ml is a 50ppm colloidal silver solution listed by Wonder Foods for water sanitising use. The 500ml bottle suits shoppers who already know this format and want the larger size for household water-sanitising tasks.
The product contains silver activated in deionised water at 50ppm. It is best assessed by the label directions, concentration, bottle size and intended water-sanitising use rather than by broad unsupported claims.
Use only as directed on the product label. Wonder Foods lists two usage notes: add half a teaspoon to a glass of water and leave it to stand for five minutes; or, for water sanitising, combine one teaspoon with one teaspoon of 3% hydrogen peroxide per litre of water and leave it to stand for 20 minutes.
Do not use with metal instruments or containers. Check the ingredients and directions before purchase, especially if you are buying for a specific household use or need to avoid silver-based products.
