## The Art of Topping Up

<http://static1.squarespace.com/static/595689fc9de4bbc892200518/t/59568ac85fd63b5f292875f1/1498845398005//img.png.com/static/595689fc9de4bbc892200518/t/59568ac85fd63b5f292875f2/1498843848468/1000w/>

I never know when inspiration for a blog may come  
 along.   Sometimes it’s a result of a  
 question I received, or a newspaper, magazine or peer reviewed article I’ve  
 read, or some ridiculous post on Facebook.    
This week, it happened when I checked into my hotel room after a rather  
 brutal travel day that kept me up for over 22 hours.   After ending up in the wrong hotel and  
 charming my way into a room and a cancellation at my other hotel, I crashed -  
 but not before I took the picture that happens to be the inspiration for this  
 blog.

Maybe it was because I was punch drunk from being over  
 tired, but the sight of these refillable containers in a well-respected hotel  
 chain made me cringe, and yet it didn’t stop me from jumping into the tub to  
 take a picture.  I was also sure to avoid  
 the use of any of the soap they had offered the next morning.  Why?   
 Because topping up bulk soaps is just plain gross.  In fact 1 in 4 dispensers in public bathrooms  
 are contaminated.  Combine that with the  
 fact that there is enough evidence from published studies proving that bacteria  
 can be found and thrive in soap dispensers, you can be sure that I will not be using  
 it and risk spreading those germs all over my hands (or body or hair).

One example is a study by [Zapka et al](http://pubmedcentralcanada.ca/pmcc/articles/PMC3126420/)  
 that looked at bacterial hand contamination and transfer after use of  
 refillable soap dispensers. The study showed that washing hands with  
 contaminated liquid soap actually increases the number of gram-negative  
 bacteria on hands, directly demonstrating that bacteria from contaminated hands  
 can be transferred to secondary surfaces. The researchers concluded that washing  
 with contaminated soap not only defeats the purpose of hand washing but may  
 contribute to the transmission of potentially harmful bacteria. 

Don’t believe that the problem only lies with hand  
 soaps.  The disinfectants we use for  
 daily disinfection, particularly if you’re using a concentrate that needs to be  
 diluted can be just a bad.  There have  
 been reports of [bacteria  
 growing in solutions of QUATs](http://www.ncbi.nlm.nih.gov/pubmed/11105107) and that surfaces were dirtier after cleaning  
 than before cleaning when conducting ATP tests.   
 One of my favorite questions from the field is whether you can add some  
 of the same “juice” found in premoistened wipes and poor it into the wipes to  
 re-wet them because they have dried out.   
 The answer to that is NO.  If you  
 do not want your wipes to dry, ensure the lid on your wipes container is closed!<https://www.blogger.com/null>

I hope I haven’t scared you from using soap dispensers in  
 public.  Hand hygiene is of course  
 critical to our well-being.  I do hope  
 that you’ll look at refillable soap and disinfectant containers in a new way  
 and [join  
 me in the “war” against topping up](http://talkcleantome.blogspot.ca/2012/02/miss-manners-proper-etiquette-for.html)!
