Does Nano TiO2 liquid get rid of cigarette odors from tar and nicotine that have penetrated surfaces?
Yes. If a second hand smoke contaminated surface (second hand smoke is known to have over 400 known cancer causing chemicals) is treated with TiO2 PCO Solution, the odor will soon disappear. However, the discoloration caused by second hand smoke does not disappear. It is therefore advisable to first wash smoke contaminated surfaces that show discoloration before treatment. 16.
