Bean-Tech recommended de-scaling agent vs white vinegar.

Anyone have a mail order source for de-scaling agent?

Citric Acid, available most anywhere. I carry ScaleKleen by Everpure $26 a bag, makes 5 gallons. Where you located so I can point you towards a rep in your area?

Do a google search for Cleancaf. I am a distributor of cleancaf and it works great! Cleancaf is now certified Organic too!

Citric acid can be got semi bulk in some asian food shops, and of course it is foodgrade. Never liked the idea of vinegar. Some use lactic acid too.
I also use scalekleen
