PEVA shower curtains are less likely to breed mold in a humid environment than ordinary plastic shower curtains, but they are not completely mold-free. Its anti-mold performance mainly depends on the characteristics of the material itself and the environment in which it is used.

PEVA is an environmentally friendly and non-toxic polymer material with good anti-mold performance. First, the surface porosity of PEVA is low, the material is dense and smooth, and it is not easy to absorb moisture and dirt, reducing the conditions for mold growth. Secondly, PEVA itself is hydrophobic, which can effectively waterproof and quickly drain moisture to avoid long-term moisture, and the growth of mold requires a continuous humid environment. In addition, PEVA usually does not contain plasticizers, which are chemicals that decompose and attract microorganisms in certain situations, while the stable structure of PEVA reduces the possibility of mold attachment.

Despite the anti-mold advantages of PEVA shower curtains, mold may still appear in certain situations. For example, if the shower curtain is in a state of water accumulation for a long time, or the bathroom is poorly ventilated, resulting in the inability of moisture to evaporate in time, mold may still grow slowly. In addition, if soap stains, sebum, hard water scale and other organic matter accumulate on the surface of the shower curtain, these dirt will become a source of nutrition for mold and promote its reproduction. In addition, the mildew resistance of PEVA shower curtains of different qualities is also different. Some low-priced products may add fillers or recycled materials, resulting in reduced mildew resistance.

In order to avoid mildew on PEVA shower curtains to the greatest extent, you can wipe it with a damp cloth, or spray diluted white vinegar or baking soda water for disinfection, and then let it air dry naturally. Some PEVA shower curtains support machine washing, but frequent washing may affect the service life. Try to open the shower curtain after each use to allow it to be fully ventilated and dried, and avoid folding it for a long time or sticking it to the wall. Some high-end PEVA shower curtains will add antibacterial coatings, which can further inhibit the growth of mold and bacteria.

The mildew resistance of shower curtains of different materials in humid environments is also different. PVC shower curtains are more prone to mildew than PEVA because they contain plasticizers and are easy to absorb dirt on the surface. Although some polyester shower curtains have a waterproof coating, once the coating wears off, the fabric easily absorbs moisture, increasing the risk of mold. EVA shower curtains have similar performance to PEVA, but are usually harder and have similar mildew resistance.
