E-cloths® are made from the highest quality polyester / polyamide microfiber on the market. Polyester is lipophilic (attracts oil & grease), while polyamide is hydrophilic (attracts water). After extrusion, the fibers are split into scores of microscopic strands, giving you many more "cleaning edges" than typical microfibers, to physically scrape away dirt, grease, and bacteria.
The superior E-cloth manufacturing process costs more, but the cleaning effectiveness and durability are well worth it! Guaranteed to last through 300 wash cycles using hot water (200°F) (assuming 1 wash per week--that's six years!). E-cloth has been endorsed by dozens of kitchen and bath appliance manufacturers in the United Kingdom.
