Oligodynamic effects take some time to kick in and are not equally effectively against all micro-organisms. Silver therefore primarily exerts a long-lasting, preservative, bacteriostatic effect.
Higher doses of silver do not necessarily work faster or better. One option, therefore, is to enhance the biocidal effect of silver by using it in combination with other substances.
In combination with oxidising substances such as hydrogen peroxide, the effects are synergistic, producing a highly effective biocidal complex.
