What You Never Knew About Doing the Dishes With a Sponge

After living with college roommates that couldn't seem to do the dishes properly, I realized I had to get the word out there about proper dishwashing duty.

Step 1 Dishsoap and Sponges

The first thing to realize is that dishwashing is not about sanitizing (killing the bacteria and viruses on) your dishes. If you look on your dishsoap (any brand will do), you will notice that it does not claim to "disinfect" your dishes!

What is the point of dishwashing?
To remove food, scum, scents, flavors, grease, oil, etc. from your dishes.

What is the best tool to use?
Use a sponge that has a scrubby side on it. This way you can soak up soapy water to scrub away at your dishes with. Using a plain sponge with no scrub is pointless - it won't scrub the food or grease off of your dishes!

How do I get rid of the "germs?"
Washing your dishes will help get rid of most of them, and the rest tend to die once the dishes dry off (bacteria can't live without water!). However, if you're concerned, you could always rinse your dishes with a 1/20 bleach dilution, or add a tiny bit of bleach to your dishsoap.

Great suggestion of sanitizing the sponge in the microwave oven. One of my pet peeves is people drying dishes with a dish towel - usually the same one they dried their hands on! It's much more sanitary (and easier) to just let the dishes air dry in a dish rack (which should also be sanitized from time to time too) or on a freshly cleaned kitchen countertop.

Have to comment as a public health RN. Soap acts to "wash away" bacteria, so, although its job is not to kill bacteria, it "moves it on out."

it says on dawn not to mix with bleach... jus sayin.

ummmm. adding bleach to detergent I believe creates a chemical reaction which is not healthy, I believe by a gas that occurs. You might like to use a gas mask. I use a dishbrush, which means the dishwater can be very hot.. Using a sponge would mean that the water would be somewhat cooler. Also with very hot water everything dries very quickly, and can be stored away and not sitting on the counter with people contaminating it.

Hi Katie, thank you for your reply, I have never heard of bleach and dish soap creating a toxic gas, if you have a reference for that please let me know! Most bacteria do die at 100C, which is the boiling point of water, but some bacteria have been shown to live up to 132C! The temperature at which hot water comes out of your tap is not hot enough to kill bacteria.

The detergent with bleach danger is a myth.
Bleach and ammonia, or bleach and toilet cleaner (lye types) does make toxic gasses similar to those used in World War One. The chlorine in bleach needs a strong reagent to form chlorine gas, not detergent.

Detergent is fairly innocus stuff. A little bleach is a good idea for sterilization, but don't over do it.

Happy dishwashing to you!

A little bacteria never hurt anybody,Great tips.

use microwave to sanitize your sponge.

most dish soap is anti-bacterial though, which means its disinfecting.

[aboddy]

Hi Kayla, thank you for your reply, dish soap is naturally anti-bacterial because of the nature of its chemistry, but it does not kill a significant proportion of bacteria, and it doesn't kill all species of bacteria. It is also ineffective against viruses. Although strong disinfectants are not required for the sanitization of most dishes, they are required for killing bacteria in sponges, and are a good idea for heavy-bacterial-growth areas like cutting boards and sink drains.

For more information about disinfectants see these websites:

A couple of good tips here. Personally I use the scrubber side for the heavy duty and then the non-scrub side for the final wipe-down.

hey! :D i have that cutting board, from the dollar store, my fav. place. haha ;)

If you add vinegar to your rinse water, you can do two things: one, reduce the amount of soap residue (I usually use too much dish soap, so this is something I have to watch for) and two, it is antibacterial: http://www.ncbi.nlm.nih.gov/pubmed/9209126 so you can kill most of the crudlies.

I've seen another article somewhere on the Internets to the effect that a 10% vinegar wipedown is good for counters, too. And I haven't noticed any 'pickly' smell.

my wife showed me that bit about the sponge in microwave. very handy. putting it in the dishwasher works as well. but i guess if you have a dishwasher, chances are you dont have much use for a sponge

[YoannM]

My roommates should read this... really nice and important tutorial.

[dchall8]

This should be required (annual) reading for everybody over age 8. 

Another suggestion would be to have more than one sponge going so each one can dry completely between uses. 

[flyingpuppy]

Agreed! Make it mandatory!

a clean kitchen is a happy kitchen, great job
