Sponge and cloth cleaning device

Abstract

A relatively thick sponge has a washable microfiber cloth that removably covers at least a portion of the sponge, and is particularly well adapted for automotive use by virtue of a microfiber pile on the cloth. Preferred cloth coverings have microfibers with a length (pile height) of between 0.5 and 0.11 cm, and more preferably between 0.7 and 0.9 cm. The sponge can be any suitable size and shape, but is preferably dog bone shaped, having a length of at least 10 cm, a width of at least 6 cm, and a thickness of at least 2 cm. The cloth is preferably sized and dimensioned to completely enclose the sponge.

Description

BACKGROUND [0001] Sponges and cloths are each well-known tools for cleaning, drying, waxing, polishing and so forth, and each has its own advantages and disadvantages. Sponges can quickly absorb a significant quantity of liquid, and can dispense that liquid over a wide surface. Thus, in washing a car it is commonplace to use a sponge to bring soap and water from a bucket to the top or sides of a automobile. A problem, however, is that sponges tend to readily damaged when used on a surface having edges and corners, such as that often found on decorative wheels. In those instances a cloth is a better choice, because the cloth is physically stronger. Unfortunately, cloths do not generally hold liquids as readily as a sponge, and can be too abrasive when used on a glossy surface such as that of a highly finished car. [0002] There are combinations of sponges and cloths in the prior art. For example, a combination of absorbent sponge and machine washable cloth cover is known for use in a ...

Problems solved by technology

A problem, however, is that sponges tend to readily damaged when used on a surface having edges and corners, such as that often found on decorative wheels.

Unfortunately, cloths do not generally hold liquids as readily as a sponge, and can be too abrasive when used on a glossy surface such as that of a highly finished car.

That combination, however, would not be useful for automotive care because the sponge portion is intended to be quite thin for comfort reasons, and is too thin to hold sufficient liquid.

In addition, the contemplated terry cloth or other towel-like cover can well be destructive to automotive finishes.

Here the sponge can be considerably thicker, but the cover is still inappropriate for automotive and many other uses.

Indeed, the cloth portion is intended to be somewhat abrasive to assist in cleaning the skin.

None of those products would be at all useful for cleaning and polishing high glass surfaces such as automotive finishes.
