Waffle weave is the perfect material for cleaning glass - it's not only highly absorbent due to a larger surface area, but it has more 'bite' or 'cut' than regular microfibre. Not so good on soft paint, but perfect for stubborn marks on glass!
This Supernatural Window Waffle is made from the deepest waffle weave microfibre that we could find, and it's white - so you can see exactly how much contamination you've removed (and how much dirt you may be inadvertently reapplying).
Finally, remember that this cloth isn't just for glass, despite its name. It also makes a perfect metal polishing cloth, thanks to that durable and tenacious waffle profile.
Care of microfibre cloths. All our microfibres are fully machine washable. Wash them with a non-bio liquid at 30 degrees for light soiling or 40 degrees for heavier contamination - or even better, grab some Dodo Juice Furry Liquid, which is made for the job. Avoid the use of fabric conditioners or softeners at all costs as these can make microfibre cloths water repellent. If this happens, take the cloth to the dry cleaners, or soak it in a strong APC solution overnight. Finally, you can tumble dry microfibre cloths on a low heat. High heat will damage the fibres. Consign old/dirty microfibres that are past their best to secondary duties like metal polishing.
