So, while playing around with some of the splatbooks (Arsenal in particular), I came up with a couple of interesting ideas for use with Splash Grenades, that might help out on a 'run.
Let me know if these have been done before, and feel free to post your own ideas.
C2 Splash Grenades (rating X C2, Cleaning 10m radius, Avail 4, cost 20 + (Rating X times 20) each)
A handy tool for the maid-on-the-go, the Mr. Clean brand C2 grenade is a quick, disposable method for cleaning an entire room in a span of seconds. Each "grenade" contains 30 liters of highly pressurized Ultrableach, held back by a safety catch and a three-second timer. Once the timer goes off, the catch releases, spraying everything in a ten meter radius with a wave of "cleaning power." Perfect for daycares, corporate offices, and Shadowrunners who don't want to leave evidence behind.
NOTE: This grenade doesn't actually clean the room, so much as spray it down with bleach. Not for use anywhere sensitive to horrible Ultrableach fumes.
Freeze Foam Splash Grenade (rating X Freeze Foam, 10m radius, avail (X)R, cost 20+(Rating x 4) each)
Want to prevent burglars while you're on vacation? Have to close a road in a hurry, and someone stole all the big orange barrels? Then buy the Acme brand Freeze Foam Splash Grenade! Its guaranteed to bury a 10m radius area in a wall of sturdy foam, stopping entrance, exit, and... generally all movement, really. And best of all, its porous--no need to worry about blocking airways or suffocating innocent people!
