How to take care of men's bikini? We tend to avoid washing swimsuits if we haven't swim in water which is a wrong practice because even if you haven't dipped in the water wearing Brazilian underwear you must have applied sunscreen and oil all over the body to keep your body protected from harmful sun radiations. By taking the right measures you will achieve a clean, colorful, beautiful swim wear for years.
Be a good reader: "Cleaning instructions, fabric composition and place where it is made" everything is present on the label itself so you don't have to get worried unless the label is not there.
It has to be cleaned after every wear: It's important to wash your mens bikini or Brazilian every time you wear them due to usage of sunscreens, sweat, dirt, even if you haven't taken a bath in it. The ingredients of sunscreen can ruin the fabric of men's undies. Chlorine will lead to the breakdown of the material if they sit on the fibers for an extended amount of time.
