The MLS Laundry Magnets (washing without detergent) are completely different from anything you’ve ever seen or heard of before. They aren’t even really referred to as laundry balls, because this is such a unique process and technology. This is a twice-patented technology based on utilising permanent magnetic force to support the washing process. Most “laundry ball” products are usually small chemical pellets contained within a ventilated, round plastic sphere. These chemical pellets run out after a number of washes and then need to be refilled. From an environmental point of view, it is still slightly better than washing powder, but the process remains chemical (similar to washing powders) and is therefore completely different from the MLS Washing Magnets.
