next get at least 2 buckets,i used 3,and a garden hose.
one bucket,or 2 in my case,is to hold the clean sand.
other bucket is for cleaning the sand.
fill the cleaning bucket about 1/4 or 1/3 of the way up with sand.
turn on the hose and stick it in the sand and stir it up really good.
then dump the dirty water out.
i did this about 10 times each bucket full.
sounds like alot but i like it clean.
