Rated 5 out of 5 by from Best of Breed A must additive when commissioning a new system or making changes/additions to an existing installation - lives up to it's reputation - could benefit from a 'fill tube' cap to make it easy to insert into radiators through the blank-stop hole without the need to mess around with a home-made funnel !

Where is shown the expiry date on the product?

Asked by: Cosmin
Hello Cosmin. The Protector F1 does not have an expiry date, but does have a manufacture date printed in MM/YY format on the front of the bottle, just above the label. The F1 Protector has a shelf like of 5 years, so you can check if the product is still in date by checking this. Hope this helps.

What is the difference between Fernox F1 500ml cenral heating protector and Fernox MB-1 which is 4l and both of which seem to do the same thing?

Asked by: nnone
