John - The common/popular antimicrobials that are used for
white glove cleaning only have a limited effect on mold spore.
There are some high end products which are effective
sporocides, however, you generally only see the cheap stuff
being used for remediation jobs.
The problem with soda blasting is it dislodges
spores/hypha/fungal components and spreads them throughout the
remediation site and beyond. The biogrowth that is present in
cracks, crevices and pores are only driven deeper into the
surface. Then when the remediator applies their antimicrobial,
it is totally ineffective on the surviving fungal components
which have now found a new home deeper in the surface.
When the clearance study is performed, surface lifts and air
sampling show no contamination - assuming that extensive air
scrubbing, extensive HEPA vacuuming, and lots of white glove
cleaning has been performed (this is seldom the case).
However, contamination still resides in pores and non-
remediated areas of the structure. All that is necessary is
for minimal growing conditions to be met once again and presto-
chango mold contamination is back.
This is why many remediators are being called back a year
after a soda remediation job has been performed. Many times
the contamination is covering a greater area than the original
growth thanks to the spreading of contamination. Soda blasting
has a Wow Factor by abrading surfaces to a clean appearance.
What the customer does not understand is that the rest of
their structure is now contaminated. Geee, thanks a lot.
Yet another gimmic from the remediation industry.
