What
is Dry Ice Cleaning?
Cleaning
with Dry Ice is Clean and Safe
Dry ice cleaning
(also known as dry ice blasting, dry ice blast cleaning, and
dry ice dusting) is similar to sand blasting, plastic bead blasting,
or soda blasting where a medium is accelerated in a pressurized
air stream to impact a surface to be cleaned or prepared. But
that's where the similarity ends.
Instead of using
hard abrasive media to grind on a surface (and damage it), Dry
ice cleaning uses soft dry ice, accelerated at supersonic speeds,
and creates mini-explosions on the surface to lift the undesirable
item off the underlying substrate.

Dry
ice cleaning has many unique and superior benefits over
traditional blasting media.
Dry ice cleaning:
- is a non-abrasive,
nonflammable and nonconductive cleaning method
- is environmentally-friendly
and contains no secondary contaminants such as solvents
or grit media
- is clean
and approved for use in the food industry
- allows
most items to be cleaned in place without time-consuming
disassembly
- can be
used without damaging active electrical or mechanical
parts or creating fire hazards
- can be
used to remove production residues, release agents,
contaminants, paints, oils and biofilms
- can be
as gentle as dusting smoke damage from books or as aggressive
as removing weld slag from tooling
- can be
used for many general cleaning applications

Dry ice cleaning
uses compressed air to accelerate frozen carbon dioxide (CO2)
"dry ice" pellets to a high velocity. A compressed air supply
of 80 PSI/50 scfm can be used in this process. Dry ice pellets
can be made on-site or supplied. Pellets are made from food
grade carbon dioxide that has been specifically approved by
the FDA, the EPA and the USDA.
Carbon dioxide (CO2)is
a non-poisonous, liquefied gas, which is both inexpensive and
easily stored at work sites.
