Perspiration stains aren鈥檛 just unsightly鈥攖hey鈥檙e chemically aggressive. The acid, salt, and metallic content in sweat and antiperspirants can weaken fabrics, discolor dyes, and even cause structural breakdown. With summer heat rising and performance fabrics more common, it鈥檚 essential to have a spotter-smart strategy.
