Chemical sponges are for the removal of dry dirt, dust, and dry smoke soot residues. Our SERVPRO team uses these sponges on all of our fire jobs while cleaning. If our team needs to reach high ceilings we have poles that hold the chemical sponges up high so we can reach those areas. This is a very good way to get soot residue off of walls and ceilings. You never want to wipe fire soot off with a wet sponge, it will only smear more! We use a dry sponge for that very reason. Although, chemical sponges should not be used with protein fires because they will only smear them more. Our technicians are certified in fire restoration and we have the perfect chemicals for any size job.
