Tear gas is a group of irritant agents, usually fine solids, such as CS, CN and CR. Pepper spray, or OC, is made from chili pepper extract in an oil base. They behave differently, so cleanup methods differ.
If the heating or cooling system ran, it may have pulled irritant particles into vents and ducts and moved them to other rooms. Crews isolate and clean the system so residue does not spread again.
Glass, metal, sealed wood and plastic often clean well. Washable fabrics may be saved depending on the agent. Carpet, padding, foam and mattresses are harder, and some must be removed. The crew sorts items with you.
Cleanup can be done discreetly. Ask about unmarked vehicles and quiet work practices when you call. Crews do not discuss the job with others.
Get to fresh air, take others and pets with you, and keep everyone out of the space. Do not hose it down or mix cleaning products. If anyone has trouble breathing, call 911 or Poison Control.
Only after it is cleaned and checked. Pets and young children are closer to floors, so they can be affected more. Keep them out until the crew says the work is complete.
