Sandblasting: The term that stuck
For a long time, sand was the only medium used for blasting processes. This made the name sandblasting to be synonymous with all abrasive cleaning processes then. However, nowadays, sand is the least favorite medium used. This is because sand has unfavorable properties for the procedure.

It can cause damage to most surfaces and also to fine-tuned blasting equipment due to its impurities. The most unfavorable property of sand though is the inherent health risks it poses. Sand has a high silica percentage. Silica can lead to permanent respiratory damage if inhaled.
