Fernox and Sentinel

keyboard

Hi

Just wanted to check i understand the above products

Fernox can be used to clean the crap out of the rads, then after i have used this i need to flush out the fernox and then add clean water and a inhibtaor that stays in the system and thats called Sentinel.

That right ?

The two particular products that i have identifed

and

The other way around is correct. Use the sentinel for flushing and the fernox for long term protection.
