Any acid will do the job to a greater or lesser extent. I've always shied away from using vinegar because I don't want any lingering taste to affect the coffee. I use food grade citric acid in rotation with the 'approved cleaners' because it's far cheaper, but apparently 'creates its own build up' (no more details given, so I'm a bit skeptical).Don’t know - but that was what we used in Saudi Arabia to get the scale off two Reverse Osmosis plants!
I’ve used it ever since on a variety of kettles, coffee makers and mesh filters. Left overnight it does the business!
Only yesterday I bought a litre of Malt Vinegar in Lidl but failed to find the Lemon Juice! According to the lad at the checkout (&FYI) it is in the “Home Baking” section!
I've also heard 'dangers' about certain descalers being 'bad' for the seals/mechanicsms in espresso machines, so I'm a bit cautious about a variety of cleaners.
