Review for Fernox Cleaner F3 500ml by Mike Reynolds
6th February 2021
Used this chemical plenty when prepping a system for work , and helping to remove amounts of muck and sediment from the pipework and radiators. Works really well, and plenty in the large bottle for a big system.

As it’s recommended by most boiler manufacturers it’s a ‘no brainier’ that you are using a quality product.
It’s not the cheapest cleaner but it’s quality gives piece of mind.

Always use Fernox as they have proved so reliable over the time. This F3 cleaner I find really useful and would always recommend it. Use it on all my boiler installations.

Is the only cleaner I use. couldn't really tell you if it works as hard to compare. prefer to use a branded chemical with their filter and testing kits

Everytime i install a boiler or flush system which isn't really bad I use the Fernox f3 to flush out any debris using my machine.
