Magna Clean all day long. I have always used these and now the twin tech is out this is even better. Thre was an article in the "Professional Plumber" magazine this month and they tested 3 different ones. the fernox tf1, the Magna Clean and the Spriotech. The Magna Clean came out on top with all tests. Stick with Magna Clean mate. You cant beat quality even if it is a bit more expensive than the rest
The which report said biasi were there top boiler one year and i am sure no body would agree with that..
The magazine,s dont test them like our customers do over many years.
