[modeleng] Re: Boiler descaling

Barrie,

I use as much vinegar as I have and top it up with water. Not scientific, 
but it works.
The stronger the solution, the quicker it will work, but I'll bet you could 
have guessed that!

I leave it for a couple of hours, then check to see how much fur is still 
inside. If there is, pour the mix back in again and leave for a bit longer.

The one essential is to wash out well, VERY well. Several washes of clean 
water, preferably warm / hot at least.

Subject: [modeleng] Boiler descaling


I am thinking my 5" Britannia boiler is in need of some descaling treatment. 
I am contemplating filling it with vinegar but have not done this before on 
such a large boiler. Does anyone have any words of advice - concentration of 
vinegar, duration of treatment, amount of washing out etc.?
Thanks in advance,
