I concur with this, razor blade in a scraper cradle (stanley and screwfix do good ones they are like 2 quid) and either just use water for the soft stuff, or a spray with vinegar and wait 5 mins for the chunkier stuff, i'm constantly scraping evap lines myself, but if you do it regularly you don't need the vinegar.white vinegar works well, and a razor blade.
Ha! I used to own a Tandberg - way back then.Still got some left over when I used to edit sound effects of 1/4 reel to reel tapes
