Whilst I am not aware of its specific use on bronze items I can
confirm that several police enforcement units here in the United
Kingdom use our Safe Paint and Varnish Remover to safely and easily
remove graffiti from a wide variety of surfaces.

When used in conjunction with our Masonry Wash the product works
extremely effectively to remove graffiti from stone and brickwork.

Safe Paint and Varnish Remover is a non-caustic conservation
alternative to nitromors containing a mixture of specialist
cleansing surfactants and a small amount of ethanol. It has also
proved extremely effective in the removal of epoxy adhesives from
ceramic and glass material.

Further information on both products can be obtained from our
offices here in Oxford, England and Springfield, America.
