When I first moved into my apartment I bought a clear shower curtain. I figured it was probably just a liner but it worked fine just as a shower curtain and went nicely with the black and white colors. Every so often I would have to bleach it though because it would get the black mold on it. Recently I found a shower curtain at Ikea that I really liked--it's cloth and black and grey. So I just allowed the clear shower curtain to stay behind and perform as a liner for the new curtain. but now that it's covered up, it seems to be getting even more black mold on it. The trouble with my bathroom is there is no fan. However, there is a window but we cannot leave it cracked as when we leave our apartment we have to shut all windows. The neighborhood we live in is okay but at the same time there have been break-ins in the past, so we don't take chances. I assume because of this, that is why we have such a mold problem. Is there another type of shower curtain liner that might be more resistant to mold? I am tired of bleaching the shower curtain liner every week. Help!
