yeah get a bunch of 5 gallon buckets - fill them with half ice and half water - put about 2-3 oz of trim (do not grind it up) in the buckets and hand stir with some spatulas for about 15 minutes - let it sit a few hours till the ice melts and scoop out all the leaf trying not to disturb the water too much - let it sit again for an hour or so and siphon off 90% of the water - pour all the buckets into one bucket let it sit again for at least an hour, siphon off the water again - if you have a lot of contaminate in there just keep pouring water in letting it settle and siphoning off...
after you have it looking clean strain it into a coffee filter and dry it
