Can already yellowed or grayed white laundry be made bright white again with snO2 white?Updated 7 days ago

It is very difficult to completely lighten already yellowed or grayed white laundry. Regular use of snO2 white and washing at 60 °C can lighten the color slightly over time. However, the white will never be as radiant as it was originally. snO2 white mainly has a preventative effect and helps to avoid gray haze and yellowing.
