How to clean the exteriors of a HW modelgun?

Hello out there,
I bought a used HUDSON desert eagle 44 from Yahoo jp auctions, here some pics:




the item is in good shape but it got some stains and imprints on the external surface - slide and frame - from use, so I'd like to ask how (with what kind of products) I could remove them and maybe make it shine again (well....in a way) without damaging it.
Thank to all of you for all the tips and help you could give me.
Best regards

Hi Dave -
I always use a 100% silicone spray lubricant and a cloth. Same thing I use on the cartridge inner rubber o-rings.

100% Silicone won't hurt the HW material.

Thank you a lot for your truly fast and useful reply!
Good Night and best regards again.

Same here silicone spray. Never tried a gun cloth but that might work, used for cleaning metal work and woodwork on guns, they have a believe silicone in them.

I use a gun cloth on them. Always look great afterwards
