Route21 Posted January 24, 2013 Share Posted January 24, 2013 Hi! Does anyone out there know where l can buy citric acid crystals in Petchabun? The water at our new place is hard. It's overloaded the ion-exchange unit and furred up the kettle. Many thanks in advance R21 Link to comment Share on other sites More sharing options...

It'the sort of item you might pick up on a cake making shelf, alongside baking powder, but haven't seen it in Tesco, Big C or Makro. Don't need much. Acetic acid (vinegar) would, theoretically do the same, but it has byproducts and a strong residual smell, unlike citric acid (the bitter taste in citrous fruits such as lemons/limes). Hope someone out there can help source some. R21 Link to comment Share on other sites More sharing options...
Route21 Posted February 27, 2013 Author Share Posted February 27, 2013 Found it! Many thanks to PM from chrgrims. It's working, but slow, as I suspect the reason it looks like sugar is ...... TIT. The shop has a sign outside that includes "baker" in Thai phonetic English. It's on the same side as the old "farang corner", just immediately beyond the "T" junction, coming from the 21.

Route21 Posted March 21, 2013 Author Share Posted March 21, 2013 I used a heaped teaspoonful in enough water to cover the element and, after the immediate frothing, boiled the water. It's now working great and, after the 2nd treatment, has removed all the furring from the element. R21 Link to comment Share on other sites More sharing options...
