I agree that your choice of tobacco will likely have the greatest impact on the results. Higher sugar content tobaccos will leave more unfavorable residue than lesser content ones. I'm guessing 1Q will be in the former category. Many years ago I smoked the same pipe nearly every day with no noticeable negative impact, but I was smoking SWR. I still smoke that pipe from time to time, but it has had a couple of good cleanings (in 50 years). Running a cleaner through the pipe regularly is likely the saving effort: that will remove much of the offending residue. BTW, when I was smoking during that mentioned phase, I seldom even ran a cleaner through the pipe. Yup, I was a heathen....
