i have a coupla steel tube weavers that need cleaning or some such. lenses appear to have dust or rust on them(inside lenses). need to have them cleaned inside. don't want to drop a whole lot on these as they are not real valuable but, they are good steel tube weavers. the scopes work as is but very hard to see through. if anyone can help, i'd appreciate it. have a good'un, bubba.
