Hi Willy, sorry you are having a hard time getting the water stains off your plant pots. Hope this will help you. First, you have to wash each pot inside and out with soap and water and rinse well. Then scrub the outside lightly with a stiff brush and full-strength household vinegar. Rinse and allow to dry thoroughly. Next, apply a very light coat of mineral oil or light cooking oil around the outside surface.Jun 6, 1997
if no plants are in it soak them in vinegar in plastic tub it will loosen mineral build then use green scrubber sponge or wire brush may need to bleach the remaining stains or you can use CLR like the vinegar.
