Microfibre Cloths by Peppers Australia are the best we could find at a reasonable price to pass onto our customers.

These are Lint-free, streak-free, ultra soft and can be washed 400+ times whilst still upholding its integrity.
They are safe to use on all surfaces, including delicate surfaces like electronic screens, without leaving any scratches or marks. 99% of all dust, dirt and germs are lifted from the surface and trapped in the cloth. We have been using these on our trucks for over a year and found them to be strong, durable and most importantly washable.
