Descaler removes mineral build-up better than vinegar, without the smell. Regular descaling will help extend the life of the machine and maintain a consistent temperature. Cleaning is the process of removing the coffee oils that will affect the taste that you want from your carefully selected coffee beans. Vinegar is a relatively weak acid that won't clean away much coffee oil residues. Coffee is by nature a very oily substance. Over time, coffee oils accumulate inside of your machine. If allowed to develop, residue inside will eventually clog the machine and cause it to malfunction.
