that is a tough one. i would say since it is metal you should probably not use any chemicals to clean it then. if it were glass i would say you could with any number of chemicals but not with metal cause might cause some sort of reaction that might make toxic products that you might not want to smoke or might mess up your pipe. i would say just scrape the resin out of the pipe is your best bet. good luck.
rnf232s Reviewed by rnf232s on . How should i clean it? i have this little metal piece i use alot, there is alot of resin left around the bowl, so i wanted to try and clean it out tonight. My friend says dont do it to the pipe it has a bad alchol taste to it (thats what i was planning to use), my other friend said not to do it and just scratch it off, what do u guys think? Rating: 5
