Managed to buy washing soda today - it seems to have suddenly disappeared from the supermarkets. For me, this is an essential thing to have in the house. It's the only thing that actually kills viruses if you wash surfaces, etc in case of any viral illnesses going around. You can clean silver by putting it in an aluminium pot with washing soda and hot water and leaving it for a while as the tarnish lifts off. When the bath is truly filthy, washing soda in the bathwater (after you get out) will lift off that greasy muck.
