How to Clean Your Kitchen Sponge

It’s a beautiful sunny, Sunday morning and you choose to do a full kitchen clean out. You clean your fridge, cabinets, sink, walls and counters. It must be such a relief that your kitchen is now as good as new, well almost. Unfortunately, you forgot to clean your kitchen sponge. 

Think about the last time you decided to clean your kitchen sponge. Can’t remember? 

Most people, including myself, tend to use a kitchen sponge day-in and day-out until it attracts a musty odor. After that we just toss it and move on to the next.

The most important question is, how long do we use our sponges before we replace them? Normal human behavior causes us to use our kitchen sponges up until it falls apart; however, as we try to save money and resources we tend to do a lot more damage in the long run.

As we continue to use our kitchen sponges multiple times a day, moisture will cling onto the tiny crevices in the sponge. 

Although it may seem harmless, this opens up a window of opportunity for all types of pathogens such as yeast and molds. 

Unfortunately, a simple run through hot water is not as effective of a cleaning method as we once thought. Hot water does not kill the bacteria living in your sponge. 

This means that you’re wiping down your dishes with bacteria and potentially mold.

I know, the irony, right? The thing you use to clean your dishes is potentially dirtier than the actual dishes you’re cleaning. 

As funny as it sounds, it’s a serious situation when mold and bacteria is involved. This could mean your dishes are consistently infected with bacteria. This can cause certain foodborne illnesses.

Although this all may make some people feel on edge, bacteria build up is very avoidable.

Follow one of the three simple methods below to take your sponge from nasty to new!

Method #2: Soak and Rinse!

This method utilizes the same concept as the first. The only difference is that you do not need a washer machine. Fill a bucket up with a gallon of water and ¾ cup of bleach. Let the sponge soak for about 5-10 minutes. Bleach is highly effective as it acts as a disinfectant. According to Info.gov.hk, its active ingredient, sodium hypochlorite, is effective in killing bacteria. It is very important to kill the bacteria of the sponge. Sometimes people may make the mistake of only removing surface stains and not getting a deep clean. This becomes a hazard because bacteria will continue to build up on your sponge, and you’ll continue to wipe the sponge all over your dishes; thus, your efforts to clean dishes become counterproductive.

Method #3: Make it to the Microwave!

This method is a two-step process being the fact that each step alone will not remove bacteria altogether. Make sure that you have a microwave, it is crucial! First off, soak your sponge in dishwashing detergent and hot water. This step is very beneficial as it cleans the surface of the sponge.

Next, place your wet sponge in your microwave on high for two minutes. Be sure that your sponge is wet when you put it in the microwave; if not, you run the risk of your kitchen sponge catching on fire. Although the risk of any danger is very small, you should stand near the microwave just in case. It is imperative that both steps are done in this method due to the fact that only the steps are not sufficient on their own. The first step removes all of the dirt from the surface, whereas the second step really gets deep into the sponge and removes all of the bacteria, making your sponge as good as new!
