I've been using Fernox F3 and on occasion Sentinel X400 to chemically flush out old 8mm microbore heating systems. I've had mixed results with both products, although they generally do the job.
I'm thinking of trying the fast acting stuff Sentinel X800, on a very old and never cleaned 8mm microbore system, which the manufacturers claim works in an hour.
Has anyone tried this stuff or is there something even better than is recommended?
