As a suggestion with regard to Enamel Thinners, I have always used Humbrol Thinners as it does not stink to high heaven, is gentle and I have never found an issue with it. It is quite expensive but I would never use it for cleaning brushes as cheaper white spirit works for that.

Mig and AK odourless is good but when I last bought some it made the Humbrol  made Humbrol look cheap.
