Abstract:
A sponge used as a cleaning article that employs passive means to deter the growth of microorganisms within the sponge and reduces the possibility of cross-contamination. The sponge is capable of being placed or stowed on a surface in a vertical orientation such that its outer surfaces will be maximally exposed to air, thereby increasing the rate at which moisture can evaporate from the sponge, and therefore, making it less susceptible and more inhospitable to microbial growth. To achieve a practical and reliable degree of stability, a sticky elastomeric gel is incorporated onto the sponge's bottom surface, possessing sufficient adhesive strength to securely maintain the sponge in an upright position, yet permitting the sponge to be easily removed from the surface, while at the same time providing a prophylactic barrier between the sponge and the surface, further reducing the possibility of cross-contamination.
