I recently purchased 4 old coiled brotforms and am very anxious to give them a go. I chose these particular ones based on their interior smoothness (little or no fiber hairs) but they have been sitting in this antique store/ warehouse for who knows how long and really need some sort of cleaning. I have taken a stiff nylon brush to them (wire brush proved too rough) but I hesitate sticking them in a tub of hot, soapy water for fear of permenently raising the grain/ fibers of the wicker/ rattan. Does anyone have any experience cleaning old brotforms? Any advise??
