Hey guys I got at Wookie Catamaran on ebay a while ago and just got to building it now and there is a lot  of dust. I'm not trying to file or anything I just want to know how to remove all of it easy, and I've gotten a few with dust before but this one is really bad some of them I can barely tell what color they are. If you guys could help me out that'd be great. 

I usually soak the parts in warm water and dish soap overnight, then rinse and let air dry.  Some parts with you might have to scrub with a soft toothbrush to get gunk out of smaller crevices.  This method has always worked well for me.  Of course, don't soak any parts with stickers or they'll peel off.

 

For sets I have displayed, I usually blow them off with an air duster a few times a month to keep the dust down.

thanks for the advice I'll go try that now

There are several threads also that goes over different methods for cleaning.  They can be easily found with the forum search function.

a soft unused paint brush will help as well.
