depends what one you want to clean.
one you can't touch unless your corgi reg as it is in the combustion chamber.
and the second if you don't know what it looks like how the hell you gonna clean it and get it out.

if your just trying to save a few bob don't bother cause 9/10 diyers who touch boiler bugger it up and costs them twice as much. (which is what i like to see)

sonray heating.
