What type of contaminants can waterjetting address that abrasive blasting cannot?

Waterjetting is particularly effective at removing water-soluble contaminants due to the nature of how it operates. When waterjetting, high-pressure water is used, which can penetrate and displace substances that dissolve in water, such as salts, sugars, and other organic materials. This capability allows for a thorough cleaning of surfaces that have these contaminants without causing damage to the underlying substrate.

In contrast, abrasive blasting typically uses solid media to physically remove materials from surfaces. While it can clean off rust, old coatings, and other debris, it does not effectively remove water-soluble substances. These contaminants often require moist environments for complete removal, which waterjetting excels at providing. Thus, waterjetting is the superior method for addressing such specific types of contaminants.
