My Keurig Brewer is clean!  The Brewer Cleansing Kit was exactly what I needed.  
It comes with a bottle descaling solution and rinse pods.  The instructions for the descaling solution is on the bottle, but you have to pull up the label to find them.  
The cleaning process using the solution is simple but does takes a while to complete.  
I haven't used one of the rinse pods yet, but they seem to be simple to use.  
If your looking for something to clean your Brewer, i highly recommend this Brewer Cleansing Kit!
