And if you do find residues, what do you do then? Your only recourse is to go and buy a bottle of high purity Xylene - as the manual said you should do in the first place. So now you have had to buy TWO bottles of Xylene to fill your bubble chamber and it has become a VERY expensive exercise.
The cheapest solution is to buy ONE bottle of the high purity Xylene, which you know will do the job.
