No, just the opposite. I fill the bowl and shank and let it swish from one to other for about 20-30 seconds then rinse with water as normal. I find it removes the oils and gunk easier.w
Black coffee? WOW ... but as I've said before, "Who says there's no value to this thread?".
Will be cleaning couple pipes soon & instead of using Canadian Whisky, I'll try black coffee. Very intriguing! Will this render any type of ghost? Can't wait ...
