You cannot wash burlap in the washing machine. I tried it one time and it disintegrated all over everything. You can however hang it on the side of a fence, wash it with a strong hose and let it air dry.
Hope this helps.

Subject: re: Quiet washing burlap ??
Hi, I was thinking the same thing this morning, we actually have a small reprieve in the rain this morning. If it's like this anywhere else on the East Coast people are getting things done outside. It has been raining almost constantly for the last few weeks !
While I'm on here... Anyone know if you can wash burlap ??? I have some at school that seems a bit dusty.
