If all you are doing is a set of forks, and the container isnt massive, you will easily clean them up with 3-4 table spoons of the crystals. if the container is big with lots of water you will need to increase the quantity.

Leave em in there for around 24 hours, but check back on them after 6 to see if they're done.

...but Dan is right ... less for longer is safer :daumenhoch: nice hot water helps as well.

Pour it on green alge covered garden chairs after :angel: works a treat.

fills it up so you don't need so much water in there :daumenhoch:
