Every couple of months I have to buy a new shower curtain liner - because ours grows some weird pinky/orangey moldy mildewy grunge along the bottom of it.
How can this be avoided? I don’t mind buying new liners - they’re quite cheap - but I feel bad throwing away large pieces of vinyl 5-6 times a year - it’s not very environmentally friendly. I’ve tried buying the ones that advertise being “mildew-resistant” but with the same results. I’ve tried washing them, but no real change occurs (at least not a big enough change to justify the hassle).
