In addition to using the proper amount of soap and separating darks from lights, we keep your whites whiter using two methods. First, we distill our cleaning solvent after every load to make sure your clothes get clean, fresh solvent every time. The second thing we do to ensure your white garments stay white is by using separate cleaning machines for light garments and dark garments. This adds another layer of protection against a fugitive dye from changing the color of your white garments.
