inhibitor or sludge remover?

[svouts]

Hi, I have removed the radiators and managed to paint them after 4 months. I am ready to put them back this weekend. I also flushed them last weekend.

I am now thinking to put inhibitor (like Sentinel x100)

Or to use a sludge remover or System Restorer (like sentinel x400).

Especially for the above sludge remover, the company claims that there is no time limit for which the product can be safely left in the system.

Shall I use sludge remover or System Restorer (like sentinel x400) instead of inhibitor until late spring time when I can drain the system?

Sludge remover will loosen up and break down (into smaller pieces) sludge in the system - NOT make it disappear. Filling a system with sludge remover and not power flushing will cause future problems.

Unless you are willing to power flush first, then add inhibitor to prevent sludge forming in future.

Just add inhibitor and keep inhibitor levels higher than recommended at all times.

If you are worried about dirt in your system, I would consider fitting one of these on the return pipe near the boiler.
