How much water is suitable for washing swimsuits?

Why is it best to use water with a temperature below 30 degrees Celsius to wash swimsuits?

Chlorinated water in swimming pools can shorten the lifespan of swimsuits, and proper use of swimsuits is also important. Staff from the Provincial Quality Supervision Bureau suggest that consumers can fully wet their swimsuits with clean water before entering the water, which can reduce the infiltration and corrosion of chlorinated water or seawater in the swimming pool, and increase the service life of swimsuits.

After swimming, remember to clean the swimsuit with clean water in a timely manner. Do not use laundry detergent, bleach, etc. The water temperature should be below 30 ℃. After hand washing, gently wring dry the swimsuit and placing it in a cool and dry place to dry. Do not use high temperature drying and ironing, nor directly expose the swimsuit to the scorching sun to avoid the fabric becoming hard and brittle, which will affect normal wearing.
