Having endured a long, lonely trawl around the cleaning and detergents sections of local supermarkets, looking for something containing ammonia to strip acrylics and clean up brushes, I got my hands on a litre of 9.6 - 9.9% ammonia solution.
Any idea by how much I am going to have to dilute this stuff further for my intended use without risk to my models, modelling supplies, and small and delicate pink body? I am well aware of the handling precautions, but even so...
Do anionic tensides do a similar job? That's the active ingredient in the contents list for just about every cleaner available hereabouts.
I was last in a chemistry lab in 1979 and would appreciate some assistance here.
TIA,
Steve
