Does anyone know what (apart from their own thinners) will clean a
paint brush that has been used with Hammerite paint?

It seems to defy everything I try!

Once dry I think that is the case. Use brushes you don't want to use
again for Hammerite. B-)

It depends on the age of the paint. Original Hammerite used
1.1.1-Trichloroethane (Genklene).

My old (approx 10 years) tin of Hammerite Brush Cleaner has "Xylene"
on the label, a dimethylbenzene.
