|Alternate Media for Pressure Cleaning
|Sodium bicarbonate (soda)
||PRO: Softer than sand or shells. Shatters into dust on impact. If water is used in combination with soda, it can be rinsed into drainage systems as non-toxic residue.
CON: Not designed for repeated use as some surface damage may result.
|Silica sand: Recycled crushed glass
||PRO: Readily available. Effective. Affordable.
CON: Can be variable in size/coarseness and be very abrasive.
|Ground pecan or walnut shells
||PRO: Softer than sand and less abrasive to walls and structures. Shatters into fine dust on impact, minimizing surface damage.
CON: Higher cost-per-pound and reduced speed of clean up.
||PRO: Discharged via an air delivery system, disintegrates on impact. Both the defacement of paint residue and the dry ice are shattered, with the dry ice returning to the atmosphere, and the paint pulverized to a size that is undetectable around the work vicinity. Comes in variety of sizes for different applications.
CON: Costs are higher than the traditional blasting methods.
|Other options: Ground corn cobs, rubber, carbon flint, gemstones
||PRO: New media are in development.
CON: May be more expensive. Unproven for some applications.
