Microfiber cleaning cloths provide excellent lint-free cleaning for any surface. Ideal for countertops， porcelain， chrome， glass and wood. Ultra-fine densely bundled microscopic fibers form a cleaning surface 40 times greater than regular cotton fiber to remove substantially more dust， dirt and bacteria than conventional cleaning products. Cloths are color-coded. Blue suede is specially designed and knitted for cleaning glass and mirrors. Other cloths in green， pink and yellow are designed for general-purpose cleaning. They trap dirt and dust and can be laundered extensively， but not with fabric softener. The cloth effectively removes bacteria without the need for chemicals. It can remove 99 percent of bacteria with water alone.
