Mixing Cleaning Products

[chudsy]

Hi All,
Is it a wise move to add X200 & X400 at the same time to clean the system as I've got a major kettling problem after restarting the heating system after coming back from holidays.
If not should I go with the X200 for a few days then add the X400?
Regards
Paul.

if you ain't bought it yet x800

or if you really want results DS40 don't use it if you have any dodgy valves/joints etc

no point on mixing them IMHO

Thanks Kev,
Will the X800 have as good an effect as the X200 for silencing the boiler??
The DS40 looks like a pretty mean bit of stuff too!!
Regards
Paul.
