SKU18020 DECONTAMINATION SOLUTION (STB) MIL-D-12468

One such decontaminant is supertropical bleach (STB). STB is a mixture of chlorinated lime and calcium oxide

containing about 30% available chlorine. It can be used either as a dry mix or as a slurry to decontaminate some

equipment surfaces and terrain. The dry mix is prepared with two parts bleach to three parts earth by volume.

A slurry typically consists of 40 parts STB to 60 parts by weight of water. This material is then sprayed or swabbed

on the contaminated surface. 
STB is an effective decontaminant for mustard, lewisite, and VX. It is less effective against nerve agents other than VX.
