Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to U.S. application Serial No. 18/934,574 filed November 1, 2024, the disclosure of which is hereby incorporated in its entirety by reference herein. TECHNICAL FIELD The present technology relates to stopper scrubbers for use in sinks and methods of using stopper scrubbers in sinks, and more particularly to such stopper scrubbers that receive and conduct light. BACKGROUND When a food waste disposal is installed under a sink, a sink flange is installed that often includes a baffle. For example, Figure 1 illustrates a sink 10 that has a garbage disposal (not shown) installed under the sink 10. The sink flange 12 and baffle 14 of the garbage disposal can be seen in the drain of the sink. Generally, sink stoppers are known for use with sinks, including sinks that have food waste disposals. A conventional sink stopper is configured to cover a drain and stop the flow of water into the drain, retaining any water or other materials in the sink. Additionally, cleaning tools, such as scrubbers, are often used at sinks to scrub surfaces of the sink, as well as remove food material from dishes and utensils. This food material is often transferred to the cleaning tools, potentially building up to an undesirable amount of bacteria, fungi, yeast, mold, and mildew that can be transferred to other surfaces around the sink. The sink stopper can also become inundated with these undesirable microbes. BRIEF DESCRIPTION OF THE DRAWINGS Specific examples have been chosen for purposes of illustration and description, and are shown in the accompanying drawings, forming a part of the specification. Figure 1 is a perspective view of one example of a prior art sink flange with a baffle installed in a sink.Figure 2 is a first front perspective view of one embodiment of a stopper scrubber of the present technology, with the stopper scrubber in an upright position.Figure 3 is a second front perspective view of the stopper scrubber of Figure 2, with the stopper scrubber in a resting position.Figure 4 is a top plan view of the stopper scrubber of Figures 2-3.Figure 5 is a bottom perspective view of the stopper scrubber of Figures 2-4.Figure 6 is a perspective view of the stopper scrubber of Figures 2-5 in an inserted position in a sink flange installed in a sink.Figure 7 is a front perspective view of a second embodiment of a stopper scrubber of the present technology, with the stopper scrubber in an upright position.Figure 8 is a bottom perspective view of the stopper scrubber of Figure 7.Figure 9 is a partly cross-sectional, partly front elevation view of a food waste disposer assembly having an antimicrobial light source mounted in relation to a sink and a stopper scrubber of Figures 2-6.Figure 10 is a flow chart of one example of a method of using a stopper scrubber of the present technology.
