I had better results with alcohol or acetone than laquer thinner, but it  
might have been that the laquer thinner bottle was contaminated by wetting  
a greasy rag for other purpuses.

(By the way to avoid solvent contamination i found it extremely useful to  
glue a bicycle valve into the stopper of each solvent bottle i have  
(remove the ball or rubber hose). These valves come with a nice plastic  
screw-cap. Ideal small-amount dripping dispenser. just to make that clear  
again, the one-way function is disabled, the valve just acts as a nice  
metal stub with a proper screw-on cap.)

A heavier toner layer seems to be a good idea too.

You can use IPA or ethanol instead of acetone, works just as well (even  
easier to us because it evaporates slower). I wouldn't use laquer thinner  
simply because you never know what is in there.
Use safety glasses.
