my goofy newp, modern greyside .25.. but.. how should I clean it ?!

after seeing this design, I started keeping an eye out for it. I found a place selling the original canada day package (t-shirt, etc), so I picked it up !
I opened the mint packaging and was amazed at the reflectivity of the coin, then I noticed the smeary stuff on it ! what's the deal ? this was in the original mint packaging, does the canadian mint store this stuff in plastic ? where's the haze from ? more importantly, can I get rid of it ? Im not sure the safest way to protect the base metal of the coin. I know you can dip silver but can you dip nickel plated steel ?

the condition of the coin becomes clean in a flash

I recommend an acetone bath for Mr. Bullwinkle. It will remove the goo and leave the color. Remember to rinse thoroughly and pat dry (do not rub).
