You should never clean your coffee machine with vinegar.
Sometimes people are tempted to clean their coffee machines with vinegar because vinegar in readily available in most household cupboards and it is less expensive than cleaning products. However, we strongly recommend to our customers to never use vinegar to clean or descale their coffee machines. Vinegar is aggressive and it could cause irreparable damage to your coffee machine. Instead of using vinegar to descale your machine, we recommend using our descaler which has been tested and approved for your coffee machine and is easy to use.
