I have a Breville automatic tea maker. The inside is glass, stainless steel, some other metal (aluminum possibly, it’s the tea basket) and a little plastic. I love it. But after a while even the stainless steel gets discolored from exposure to the tea.
With it came one packet of cleaner. One must heat a full pot of water to boiling, put in the contents of the packet, which foams up, leave it for 5 minutes, then rinse thoroughly. This works really well. However, it is an expensive cleaner, with shipping it costs around $3.50 per packet when ordered online. The packet says the contents are sodium percarbonate and sodium carbonate.
So, I’m wondering why this is so expensive, and if there is a good substitute that is both safe and effective.
Or could I buy these ingredients in bulk and make my own? 10 pounds of sodium percarbonate costs $21.50 plus shipping, and the same amount of sodium carbonate costs $19.50 plus shipping. This would be a several lifetime supply, for the cost of maybe 10 packets of the finished product.
