One downside in using natural fabrics is that they absorb water easily, leading to mildew formation and soap stains. It is essential to keep these types of curtains dry and clean, and allow light to fall on them. As far as possible, they should be spread out to let them dry easily. Mildew and stains can be removed by washing them with detergent, or soaking them in limewater and then letting them dry. More recently, to counter such problems, these fabrics have been treated with waterproof coatings and stain-resistant formulations. Another remedy is to opt for a vinyl lining in the inner part of the shower curtain, which is exposed to water and soap.
