Residual Residue
The resin that's left in your smoking apparatus after you scrape it is the residual residue. Can also refer to the kief that's left in all the nooks and crannies of an herb grinder.
Residual residue resides inside my triple percolator even after cleaning it for two hours.
Yo! my space case is full of residual residue that I thought we sparked already.
