How good is x800 on hard magnetite particles

[Sharp Point]

As title boys n girls, will it dissolve hard particles of magnetite? These particles will dissolve in brick acid easily, but I don’t fancy putting neat brick acid in a heating system.

Thanks

I use it all the time. But have never cut a section of pope out afterwards.

use acid. fx2 or any other phosphoric acid and citric acid mixed product.

Awesome. You cannot use fx2 on aluminium rads or heat exchangers

I’ve powerflushed this very very dirty system twice using fx2 already. When I commenced the extensive plumbing alterations in this house, the 28mm circs only had a 15mm bore through them... there was a 6-7mm thick hard crust built up. I removed the majority whilst reinstalling the new pipework, but there seems to be loose particles that are stubborn to remove. It’s had a cold mains flush as well.
I can hand on heart say it’s the filthiest system I’ve come across.

Oh, all rads have been replaced too
