Their moderate aggression towards coatings is a benefit, but damage to various substrates like brick and mortar is limited. The fact that baking soda abrasive is so non-damaging to substrates is due to its softness, and its friability. Often wrongly seen as a negative, baking soda dust in contact with odor sources, means more effective odor reduction. This is both a positive and a negative when using this blast medium. Their low cost, ability to effectively strip coatings, and their safe nature make them prime candidates for many large blasting jobs such as log cabins and warehouse fires that require quantities of one-pass blasting media.
