Title: removing boiler/soot reside from external wall
Post by: Smudger on January 03, 2010, 05:12:46 pm
Hi Guys,

A client called me as they have had a new boliler installed and the wall that the vent comes from has been covered in a "soot like" substance fromn the oil burner boiler - I did a test with a mild detergent and with a good amount of scrubbing was coming off, but this is quite a large area, any other tips, for a quicker more effective clean, the wall is a yellow stippled render (not painted) and they do not want this damaged unneccesarily.

Any help much appreciated! :)

i did a similar job a few months back, and i found a wire brush and hard graft the only way, although the job i did was brick work and not render and i painted it after.

if asked again i wouldnt have done it though

Id reccommend a HIGH ALKALINE cleaning agent such as one called "JAZZ" i used to use this in my fire and flood restoration days with very good effect
soot is acidic so you need to use a alkaline cleaner to remove it
Jazz with Hot water and some elbow grease and a stiff hors hair brush
 should sort it out
you could also try some "chemical sponges" which you would use dry but it would depend if the soot residue is wet or dry so to speak

And once you have done all the cleaning you may find it bleeds back out of the surface, so if this happens you need to seal it first then paint the area.
