These microfibre glass cloths are ideal for cleaning glass and come in a generous 40 x 40cm size. The finer weave of microfibre makes for a brilliant, crystal clear finish every time. In each cloth, thousands of microscopic fibres gather and trap dirt in these amazing cloths meaning you need less water and cleaning fluid. They can be washed over and over at up to 90ºC but please don't use fabric softener as this will stop the microfibres from working.
