I'm assuming you were told to wash it because of the risk of bleeding?
I don't always do as I'm told.
I would
test it for bleeding first. You may find that the batik is one that has already been washed (by the manufacturer) in plenty of hot water to remove the wax. You can test it by getting a white kitchen towel wet, then rubbing it on the fabric. If dye transfers to the towel, then you have a bleeder.
