I've got the following reels that if anyone knows about/has worked on/knows where to point me on cleaning/lubricating I would greatly appreciate it. I do not have the years of these reels but I know none of them are even close to being new (probably all three date pre-1980s): Penn 210, Penn 155, Daiwa Sealine 27H. With a foot of new snow here in Massachusetts, its a good time for me to tend to the reels! :-) Thanks in advance for any help.

Take them apart - slowly - and take pictures and notes on each stage of dis assembly. Take the parts and put them in an egg crate in order (and orientation i.e. up & down) so that you have the order to put them back.

Otherwise, clean, grease, lube...
