You just can't use any vacuum.
When your smoke damaged furniture arrives at SERVPRO of Baltimore's Inner Harbor we first vacuum any soot and debris that is on the fabric with our industrial grade hepa filter vacuums. The next steps are using chemical treatments for odor etc and in extreme cases using our ozone chamber ( promise to get a video of that in the future :)) The first steps of any clean up are as important as the last. SERVPRO knows the correct process. Trust the experts.
