are you asking this question
a smoker gets smoke on another persons clothes. Another person cleans those clothes. The cleaning process
results in a residue buildup somewhere.
(1) can the chemicals in cigarette smoke be thoroughly cleaned from clothes?
(2) what's the best way to clean those clothes
(3) can the residue be cleaned up
The problem you're facing is there are thousands of chemicals in cigarette smokehttps://www.lung.org/stop-smoking/smoking-facts/whats-in-a-cigarette.html
of which there are nearly 100 that are considered carcinogens.
another list for you to considerhttps://www.medicalnewstoday.com/articles/215420.php#1
Some of those chemicals are water soluble, some aren't. Of those that aren't, some are soluble in acidified H2O, others in basic aqueous solutions. Some are soluble with soapy water, some aren't. There really isn't a process that 100% removes those chemicals from your clothes. You will always have trace amounts. And the washing water will most definitely contain traces of those chemicals and that gets back into our drinking water.
Probably the best way to remove those chemicals from the environment is to thoroughly burn your clothes (which converts most everything to CO2 and H2O and a few trace metal oxides). But who wants to do that.
So instead of regulating the rinse water from clothes, we have drinking water quality standards that limits the amount of things like "benzene" (which is found in cigarette smoke) to what is considered a relatively safe value. It's not zero, but most likely a harmless value.
my suggestion to you is this
(1) start with the chemicals present in cigarette smoke
(2) google chemicals EXHALED in cigarette smoke
(3) determine the concentration of those components in a standard size room based on average # of
cigarettes smoked and air turn over rate
(4) assume your clothes will have the same concentration
(5) estimate the number of clothes washed per day
(6) estimate the total amount of the predominant chemicals put into the water (assuming washing is
(7) determine if the value is within water safety standards
fyi, this probably a 2 day research project + writeup. It could make for an excellent paper if you do it well!
