Abstract: The present disclosed subject matter relates to an aqueous cleaning composition consisting essentially of malic acid, citric acid, and water, wherein the ratio of the weight ratio of malic acid to citric acid in the antimicrobial composition is between 1/1 and 50/1, and wherein the concentration of the malic and citric acids mixture in the aqueous cleaning composition is between 1% and 20%. The aqueous cleaning composition provides a minimum 3 log kill of microbes, bacteria, or viruses. The aqueous cleaning composition may optionally further include a pH indicator that provides a visual indication to the user of the effectiveness of the composition. The aqueous cleaning composition may be used to deodorize, clean, sanitize, or disinfect porous or hard surface articles and hard surfaces.

Abstract: The device cleans and disinfects sponges. The device has a tub with a cavity of sufficient space to hold paddles for wringing a sponge, a cartridge for holding a slow-dissolving disinfectant, and a sponge. The cavity is filled with a disinfectant solution. The device can be mounted on the inside wall of a sink or cabinet with an included bracket or can be stood in a base on a countertop. The device includes a warning light programmed to remind the user when to change the slow-dissolving disinfectant. The user inserts a sponge between the paddles, inserts the paddles into the cavity, and squeezes the paddles together. The user then releases the paddles, causing the sponge to absorb the disinfectant solution. When the user removes the paddles, specially-designed fluid channels quickly drain the sponge.
