Cool..

Do you know the mix quantities ?
Im doing some forks with only a small amount of rust

The more you use the faster it works, but you dont need much. 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.

Slower is better - don't go sticking fook loads in from the get go, remember you can always add more - I use 500g for a half full bath, with a bit of light scrubbing with an old toothbrush on stubborn bits. Leave em in there for around 24 hours, but check back on them after 6 to see if they're done.

I accidently put 750gms into a tub that just held a frame ... left for 24 hours ... pffftt it was fine  

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

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

don't forget to put pop bottles/bricks/whatever in the gaps between the frame & tub
fills it up so you don't need so much water in there
