Tear Gas Residue Removal 

No matter “CS”, ”CN” or “OC”, Remove Their Residue

Up to 88% of Hong Kong population is exposed to tear gas (TG) residue. Cleaning it up requires the expertise of a professional to do the job correctly.

Tear gas residue can seep into air-conditioners, furnishings, curtains & carpets, and continue to irritate the mucous membranes. Therefore, it is imperative that all tear gas residue is neutralized and the home or property is restored to a safe and healthy condition.

Ways to Stay Healthy

1.  Ventilate the premises completely;

2. Install air purifiers with H12 or above HEPA and activated carbon filters for extra adsorption of harmful chemicals;

3. Deep clean the entire home or some high-risk items like air-conditioners, curtains, upholsteries, sofas, carpets and mattresses.
