Gents, I have little time and mood to do some modelling, so I began to de-chrome some parts of my 1/25 Jo-Han 1931 Cadillac Cabriolet. For this I use Dowanol, a colour thinner and remover I can get nearby from the manufacturer. For legal reasons the label on the bottle reads "Methoxypropanol" or "Propylenglykolmethylether". Aren´t those wonderful words?
The green parts are already de-chromed, and wait for some polishing. The black container contains the solvent. I keep the lid closed to prevent too much evaporation. Inside you can see a chrome part (the black ladder like thingie). I will take it out and clean it using an old toothbrush.
Such things take their time, but I am not in a hurry. And I can do other stuff when the parts are getting worked in the solvent.
Poof. 
That's really close to what I learned in HazMat school. Mine was Methlyethylbadsh**.
