How Long Do Magic Erasers Last? The strong decontamination of the magic sponge is a result of the extremely high opening rate of its special three-dimensional network. Every part in the sponge is smaller than one ten-thousandth of a hair, and it can make good contact with the object, which makes the contact surface between magic erasers and the object almost become a vacuum, resulting in great adsorption force. The biggest difference from the traditional cleaning method in Mr.Topeco magic cleaning sponge is that the nano-picture applies the principle of physical adsorption to decontaminate and automatically adsorbs the stains on the surface of the object according to the opening of its nano-scale capillary. In the process of wiping, only water is needed, and the stains can be wiped off immediately without some detergent. There is absolutely no chemical residue, which can better protect the health of family members. Magic erasers' material is not as wear-resistant as cloth. It is just like erasers, which will wear off and peel off during friction, so its service life is limited. Many factors affect the service life of magic erasers: First, the density itself. The most important thing is the density of magic erasers. Magic erasers have many different densities. The higher the density, the more durable it is under the same conditions. Second, the use of techniques. Because magic erasers itself is fragile, they must not be used with too much force, and the usage and steps must be correct. You can't twist it with your hands or pinch it with your nails, which will reduce the service life. When in use, it's best to press the sponge flat with both hands to squeeze out the water. Let the sponge fully absorb water and use it in a wet state. Third, the roughness of the surface of the object. The rougher the surface of the object to be wiped, the greater the wear and consumption of the magic erasers, and the shorter the service life. It is suggested that when using magic eraser cleaning articles, it should be cut into the required size according to different articles, which will reduce waste and prolong the service life. For places with heavy oil pollution, it is not recommended to clean them directly with magic erasers. You can simply clean them with other sanitary ware before using magic erasers, and the effect will be better. Magic erasers itself is a consumable, just like an eraser. Normally, it will be harm during use.
