摘要：
A process for removing dried paint residues from a difficultly accessible surface is provided. The surface is contacted with a slurry of particulate solids such as sodium hydrogen carbonate in a first liquid such as N-methyl pyrrolidone which is a solvent or swellant for the paint residues, followed by a different liquid such as isopropyl alcohol in which the first liquid is soluble (and which may also optionally contain particulate solids). The surface is then further contacted with yet another liquid such as water in which both the second liquid used and the particulate solids are soluble
