What disolves oil paint. Lacquer thinner and mineral spirits. You
can mix them together. You can also try the other hard stuff like
MEK and Toluene. Add some acetone and you got paint remover.

Mineral spirits is used to thin oil paint, and clean brushes, while the
paint

is still wet. It does absolutely nothing to oil paint that has already
dried.

Mineral spirits is a slow drying base. When you disolve with lacquer thinner
and the lacquer thinner evaporates, the mineral spirits is left helping
to keep the pain WET so you can wipe it away. Thats why I say
add mineral spirits.

Yes, but lacquer thinner is at best a mediocre solvent for dried oil-based
paint. A paint stripper containing methlyene chloride works far, far better.

The OP didn't specify what stripper was used. The nasty stuff works best.
That and a wire brush.

Using a wire brush on concrete will result in eventual rust stains on the
concrete, as the steel is abraded from the brush.
