I am interested in using rice flour (I just got a Nutrimill) on linen cloths (flour sack tea towel type) to cover my dough when it is rising etc.  I was reading where they were saying use brown rice, but I have a LOT of white rice and am wondering if this would work just as well?

Do I simply spray a coating of oil on the cloth and sprinkle it with rice flour?  Does it ever need to be washed, or is this something I simply put into a plastic bag till the next time?  I know I have read about doing this somewhere, but just can't remember where or how to do it.
