So, I knew my truck had been smoked in, it it was t too bad, I thought. Did the cabin filter install, shampooed the carpet, better, but not gone. Then the other day, now that it's getting warmer, it sat in the Sun all day and It smelled like a damn ashtray.
So I called up my buddy who ran a detailing product manufacturing company for years. He said to go to his garage, grab this packet, follow the instructions and walk away. 12 hours later my truck smelled like a swimming pool, but not the slightest hint of cigarettes. 4 days later the chlorine dissappated and the truck is ggood As new. Its a stupidly easy solution and I can attest first hand that it works.
It does say for heavy odors or large interiors to use two, so maybe grab an extra and go for overkill and not have to do it again.
