I like a lot of the members here prefer to buy my oil and filters in bulk, especially when the items I need are on sale. I have a few ACDELCO PF 61 filters that I got at a really good price a couple of years ago. opened them up the other day only to find that couple of them have some rust forming. it is showing up outside the media, threads and antidranback valve. located in the seam that goes around the top of face. it is surface rust. looked inside the filters and they look the way they should .would you use these or just scrap them ? not sure if trying to clean the rust off would be a good idea, if any particles would end up in the holes of the drainback valve. I could cover all of the holes them with tape and use steel wool lightly to remove the rust. the outside of the filter is perfect. what say you ?
can anything be done to save the filter ?

If it's just a light dusting of surface rust here and there, I would use them no problem. Any oil that touches the baseplate is going into the dirty side of the filter anyway.
yep what BF said,I'd use them and sleep very good at night.
Put them in ziplock bags & suck the air out.
We had silica bags found in packging in our shop ue used for corrosion prevention inside electronic controls on machines that were exposed to big temp swings.
If its just a light dusting as daman discribes rust that is more a discoloraton very lite seems OK to use.
Body shops use chemicals that will disolve rust & basically wipe away but the residual effects are probably harmful being very caustic .
Its kind of an oil junkie's worst nightmare to have the stash rendered unuseable.

Wipe the pitted parts with oil and paper towel.
I have seem oil & grease have a negative effect where oil was applied to bare metal actually traping the moisture/humidity on the surface.
I appreciate the opinions so far. I store all of my filters in a plastic tupperware type container in my cellar, that is always full LOL ! I did try a qtip on the worst one with some LC 20 siting around the groove for a couple of hours and some of the rust came off but not all of it. figured using some LC20 would do no harm as it has been used in my engines before. guess as long as it does not make it into my engine , getting trapped in the filter,I would be ok with it. this line here " Its kind of an oil junkie's worst nightmare to have the stash rendered unuseable. " hit the nail on the head for me. having my stash go bad would defeat the reason for having it. I may have to get some pics after work today and post them up, so you can get a good look at it. thinking the place where I got them had them stored somewhere damp as the rest of my filters stored in my cellar are perfect. the weird thing is half of them have the rust and the other half have very little if any.

Store inside your house since its cool and dry, they will last 20 years
I'd get a dehumidifier for you cellar.

I do have a dehumidifier and run it all the time. try to keep my cellar dry as I have all of my stashes there along with my tools. that is what makes me think that the the filters turned out like this from where they were stored prior to me buying them. I just can not see why these filters were affected and not the other 20+ that I have had laying around.

Thats nothing hit it with a little steel wool and run it plus it's on the inlet side, IF anything did break loose the filter would catch it anyway.
I really wouldn't bring steel wool anywhere near a filter. Just use them as-is.
