Fernox F3 system cleaner

[Davefridge]

Hi all, this is my first post. Be gentle with me!
I have bought a 15 year old house & want to overhaul the heating system. I have taken off each radiator & flushed it out using a hose pipe & vigerous shaking. Now I intend to clean the system With Fernox F3 before further flushing & treating with MB-1. My question is can I trust the F3 cleaner sold on E-bay for £2.50 (plus 3.50 p&p)? I know this sells at Screwfix for £16.22.
Any comments or advice would be appreciated.

Cheers
Dave

Don't think I used it in the end. I used some stuff from Homebase that was "reduced to clear" MB1

Thats the chance u take with buying stuff off of ebay, certainly it gan be sourced a hell of alot cheaper on sites like that,

Try and always use the known products as unbranded cleaners and inhibators youd be aswell peeing into your header tank lol

Really appreciate people taking the time to reply. Only asked because I'm so torn. Got a 25 year old system and just trying to decide on best cleaning method. Just used sentinel x400 and installed magnetic filter, but now want to do one now clean bit being a microbore system im aware i need to tred gently so to speak.
