Designed for odour control, The Dirt Company formula leans on the latest sustainable science to leave your clothes with a lasting freshness. It can be used on everything, although it's a particularly perfect blend for activewear, work wear and dark clothes that typically foster faster bacteria growth and hold onto smells more than regular washing.Like all our products Advanced Wash is formulated with plant based and organic cleaning ingredients. Unlike our original laundry formula, it contains an organic antimicrobial agent that will prevent the growth of malodour causing bacteria, and help control bad smells.If odour control and lovely freshly scented clothing is what you're after, this one's for you.
