Are you new to sandblasting and unsure of which media to use?

What about glass bead?

Just learned about all of this after finding blasting media in my package that I received. Honestly, I’m kinda mad because I feel like it could be toxic to breathe in and the part should’ve been cleaned before putting into a package. Am I overthinking it?

I have a project that involves CNCing polycarbonate then sandblasting it to remove all the scratches and imperfections, what would you recommend me to use for the sand blasting material

So if i want to clean an engine bay of grease and contamination Soda blasting would be the best
