Asbestos shingles

[reflectwc 14]

I have a house that was partially burned by fire and it has asbestos shingles. I'm trying to prep it for paint and would like to clean up the shingles as best i can. What should I use (chemical) ? What are your thoughts on this project as a whole?

Thanks

I would wash with your regular house wash to see what happens but I would also be prepared to use some sodium hydroxide if your regular house wash does not budge it. Hot water will help, but be careful of the pressure. I wouldn't expect for it to come 100% clean, especially if it's been a while since the fire. The longer the soot sets the harder it is to remove.

I've washed many houses with this type of siding. In fact, I have washed 8 of them in the last few days! In general, they wash like a regular house. Where you may have a problem is if the paint is bubbling, then you'll need your turbo nozzle. The siding itself is quite hardy and will tolerate pressure - just not too much. (I reduce pressure to about 1000 with the turbo.)
