When it comes to cleaning exterior surfaces, water blasting has been a popular choice of stain removal for years. However, dry ice blasting is another method that can remove the most stubborn imprints.
Dry ice blasting is the direct exposure of surfaces, such as stone, brick or wood, to solid carbon dioxide particles through a pressurised air stream.
The thermal shock is what makes the cleaning so effective, as well as the volume change as the dry ice pellets transform into a gas.
There are many advantages of this form of surfacing cleaning, including the fact that the only remaining debris is the material that needs to be removed.
As a result, it is incredibly tidy, as it does not produce excess dust, which can be a problem with other types of cleaning blast systems.
Therefore, it does not create secondary waste that itself needs removal, nor does it produce chemical residues as the dry ice becomes a gas on impact.
The materials that have been removed from the item can simply be swept up or washed away easily, without extra consideration given to getting rid of the waste product.
It is particularly popular within the printing sector, as it can be used to clean print rollers particularly well.
Dry blast cleaning can also clean welding equipment and remove mould, silicone and rubber with ease.
Thanks to being incredibly efficient, non-abrasive, non-toxic and non-flammable, it is becoming more widely used.
Even though it is growing in popularity, it is worth noting that dry ice blasting costs more than alternative surface cleaning systems, as the material evaporates when it is not used.
As a result of this, estimates need to be given about how much dry ice is required. If the job needs more than what has been ordered, nothing can be done until the following day when another package of dry ice can be used.
