Stubborn stains and dullness on white fabrics like socks, tops, and bedding can be frustrating, but you don’t have to reach for harsh bleach that can damage fibers and logos. According to cleaning enthusiasts, Napisan is a far superior choice. Simply add two scoops to your regular wash alongside your detergent. This amazing product effectively whitens whites, removes sweat stains, and works wonders on socks, all without affecting other colors. For an 800g box of Napisan, you’ll pay just £4.50 at Asda and Morrisons, which translates to a mere 16p per use. Napisan is also available in bulk on Amazon for an even more cost-effective option.
