Dry ice blasting might be your best mold remediation option for a couple of reasons, after you compare it to other types of blasting, including sand blasting, water blasting and soda blasting.
Sand blasting is an effective cleaning method. However, it is far too abrasive and damaging to the underlying surface that’s being treated, whereas after dry ice blasting, the structural integrity of the surface typically remains in tact.
Water and steam blasting do not clean as thoroughly as dry ice blasting cleans, and there’s a greater chance that further damage will be done to the substrate, due to the water vapor and moisture component.
Soda blasting is also an effective, although messy, cleaning method for mold remediation. The main drawback with soda blasting (as well as with most other blasting methods) is that it leaves behind a secondary waste stream to deal with, which requires more time and money to complete the project.
On the other hand, with dry ice blasting, the carbon dioxide gas sublimates into the atmosphere after it impacts the surface, leaving no additional waste streams to dispose of.
To remove mold from even the hardest-to-reach corner or crevice in your home, mold remediation professionals will often use the soda blasting method, which is reliable and efficient.
