From my perspective (-and experience) the answer is 'not really' to be able to get it 100% clean. I use hot caustic to soften it (submerged for 3-4 days) and then scrape the coating away with a putty knife. In the hard-to-get-to areas, we use media under pressure to blow the softened coatings away.
