works great, if you just leave it in a closed jar for a night you can clean it off with a tooth brush and dry cloth or paper towel in the morning.
why a closed jar?
Isoprophyl fumes will give you a headache.. always try to use this in a room that has some kind of ventilation. (I never do this because for some reason I like headaches...

)
Normally you even have to wear gloves to handle this stuff, so be at least a little bit careful with this stuff
Why a tooth brush?
It is very handy when you're cleaning a very detailed toy to have a tool that is able to reach into those small openings and rough surfaces. Never,... I repeat, Never use your own tooth brush.
(oh yeah, Isoprophyl is also very good when you're using Tamiya paint...for cleaning, thinner, etc..)
also when you take out the plastic out of the Isoprophyl sometimes the translucent plastic sometimes need some extra cleaning to become shiny again.
I think I Leftlong arm in a jar for three days and he still came out ok (that blue stuff was a pain in the ass though).
If you're not sure about this yet try it with a toy you don't really care about first.
good luck
gotta go back to work and drill some holes into Blackout's legs.
