I myself do not smoke 'scrapings'. I clean my bowls in a pot of boiling water with a little detergent. Then there will still be stuff in the ribs. with a bit of work I can get most of it out. there are products out there for soaking and cleaning glass pipes.
Shovelhandle Reviewed by Shovelhandle on . Bowl inside "ribbed" scraping method I bought a glass pipe not too long ago that I want to scrape. I've been smoking for years and never have I come across a glass pipe like this one. The inside of it is almost "ribbed". Not literally but it's the closest word I could think of to describe that there is a texture inside the bowl. It is not smooth so you can't just slide a straightened paper clip or like object inside of it to get the resin. There are bumps and creases that seem to almost hide the resin from being reachable.
