Which rag is better to hide germs
By: Israhel Cruz
The purpose of this experiment was to see what dish rag hides dirt and germs better after doing dishes. I became interested in this experiment because I heard a high school student did a project kind of like this one. The information gained from this experiment will help others decide which color dish rag is better to use to do dishes.
It is important to wash your dish cloth often. Always get a new dish cloth when you have used it to wipe counters with raw meat. If you are not washing the rag right away be sure to let it air dry before putting it into the hamper. Wash the rags on hot in the regular or heavy duty cycle. The gentle cycle does not have enough agitation to activate the laundry soap. Do not use fabric softener on dish cloth because it leaves a film on the material which will stop it from getting completely clean the next time.
