A composition for use in removing polysulfide sealants or coatings. The composition comprises a thiolate such as an alkyl or phenyl thiolate with an alkali metal or Quaternary ammonium ion in a solution of dimethyl formamide or dimethyl acetamide either alone or in admixture with an aromatic solvent such as toluene or xylene. In some circumstances a disulfide compound such as diphenyl disulfide or tert butyl disulfide in the composition provides a synergistic improvement in the desealing rate. |
