European Union banned sale to general public in 2009

“Paint strippers containing DCM are used by members of the general public at home to remove paints, varnishes and lacquers both indoors and

  • utdoors. The safe use of DCM by them

cannot be ensured by training or

  • monitoring. Therefore, the only measure

effective in eliminating the risks arising for the general public from paint strippers containing DCM is a ban, with respect to the general public,

  • n the marketing, supply and use of such paint

strippers.”
