7. Use salt to remove watermarks on wooden furniture
Wooden tables are beautiful but can be hard to clean up. Especially water stains are notoriously hard to get rid of. This is another situation in which salt can help you make your life a lot easier.
Make a paste of salt and water and rub it into the stains. Once you are done removing the stains a fresh coat of varnish should be applied to make the wood look as good as new.
In case there are serious stains and other dirt you can try using bleach. Simply apply it with a toothbrush but be careful, bleach is an aggressive compound.
