Suggest a spray degreaser for sealed bearing cartridges?

[mokofoko]

I'm about to degrease and repack the cartridges in some Campy Bullet hubs (rear axle spins a bit gritty by hand with any sort of preload), and I'm having trouble picking out a spray degreaser. I prefer Finish Line Speed Degreaser, but with many bike shops currently closed, it's not an option...

Please suggest something you've tried that fits these criteria?
1). aerosol spray, non-foaming, non-citrus?
2). readily available from a common essential store (walmart, home depot, etc)
3). leaves no residue behind

Some videos and comments I've seen online suggest standard WD-40, but I'm concerned about the lubricant film it will leave behind. CRC brakekleen is also a common suggestion, but I've tried that in the past and it shriveled up the rubber cartridge shields (absolutely unacceptable!). No easy access to 99% isopropyl due to the pandemic, and I'd prefer not to mess with gas as I'm opting not to remove the cartridges from the hubs at this time. My current choices to go with are White Lightning Clean Streak Degreaser or WD-40 Bike Degreaser (apparently foaming though).

Please suggest what has worked for you in the past... I've already wasted 2+ hours reading and watching videos, and I've yet to find any real consensus on this topic. I plan to do the work tomorrow afternoon, so prompt suggestions would be very much appreciated. Thanks much.

Assuming you are going to use a dental pick or some other sharp implement to pick out the seal and expose the bearings?
If so, odorless mineral spirits has worked well for me in the past. Just soak them, Then use a toothbrush, toothpick or something similar to pick out and scour away old grease from the bearings.
The OMS will evaporate fairly quickly, and you can then pack the bearing cartridge to the brim and press the seal back in place.
Oops. Missed the aerosol part of it. Substitute the words “Brake cleaner“ for OMS.

OP needs it in a spray can because he's not removing the bearings from the hub. OMS doesn't meet that criteria.

Yep. See my last line...saw it after my initial reply.

Thanks. I'm not sure there's a product the OP will find to do what he needs.

I'd say flush the bearings with WD-40, then blow out with a can of compressed air. That's about as close as I can come up with for a solution.

Couple of things..
-Is it the rear hub bearing or a bearing in the free hub body that is gritty?
If it's the lower bearing in the FHB..really tough to access w/o removing it. Possible but difficult.

-Anything that you use to flush out the bearings(assuming you pry off the seals to expose the bearings and then try to flush)..it's going to take a while to have that whatever evaporate completely. If you don't, then adding grease to that solvent will render the added grease not as effective.

I know you don't want to do that but I'd recommend replacement of any bearing that feels like its toasted..

I'd say flush the bearings with WD-40, then blow out with a can of compressed air. That's about as close as I can come up with for a solution.

I agree and even WD40 will leave behind some 'lubricant'..but I've never been a fan of 'unseal/flush/regreease/seal back on'..for cart bearings.

I think the folks at BBinfinite recommend white lightning clean streak aerosol

Thanks all... as no new products were mentioned that fit the criteria, I think I'll go with my previous plan, which was to start with a first pass of WD-40, then do a final cleanup with white lightning clean streak (since it's non-foaming and apparently leaves no residue behind).

When I'm done I'll post with my results in case anyone else runs into a similar situation.

Thanks for the suggestion--I do have mineral spirits onhand, but not sure I want that liberally soaking in the hub area for a time. The one brake cleaner I used before for carts completely messed up the rubber shields, so I'm wary of trying any similar products.

Using a razor blade to pry off the seal--done it many times, no problems. I've tried a pick before and it didn't work as well.

At the very least, white lighting clean streak is supposed to meet all of the criteria listed... but I don't know how good it really is.

I just can't believe that there's no other similar product to Finish Line's Speed Degreaser readily available from a non-bike shop.

Hubs, freehub body is fine I believe. Applying pressure against the non-driveside has it feeling a bit rough, despite still being packed with grease. I agree it would be best to remove or replace for repacking, but I don't have the press/removal tools onhand, and the turnaround time for repairs at my LBS is 1+ week which is just way too long.

Not detecting any play, so the bearings are probably still fine (and the wheelset is less than 2 years old). Assuming just a little grit got in, which is why I"m attempting this before opting for a cartridge replacement.

I will be spraying everything down with air and waiting for a full dry overnight.

I've heard some good things about it recently, but it's hard to know what's marketing hype or general consumer praise (which means little). Will give it a shot, since it's available in all the local walmart bike sections... I guess no one here has actually use it for cleaning out cartridge bearings? I've seen 3-4 videos of people spraying down bearing cartridges with standard WD-40, but it just seems like a terrible idea to have that lubricant mixed in with the grease...

[charliedid]

Isn't the finishline spray just brake cleaner? Stuff is nasty.

[bart998]

I also have Bullet wheels and cleaned/lubed the bearing recently... I usually use Gumout Carb and Choke cleaner for this purpose... spray can, dissolves grease and deposits, evaporates quickly and leaves no oily residue to dilute/contaminate the new grease... a plus is it's cheap ($4) and widely available at most auto parts stores and Walmart.

[m_sasso]

This will do the job, evaporates super fast, dissolves oils, non-polar lubricants and zero residue. It is also certified for use in food facilities so very clean.

Should be able to pick it up from any good electronics retailer.

Interesting, same situation--carts still seated during the clean? And it didn't cause any damage or leave any smells etc? I may have to give that a shot. $3.18 at walmart, half the price of the white lightning.

I think I saw that recommended elsewhere, but I'm not quite sure where I'd find it locally, and the google locator is no help for this one. CRC contact cleaner is carried at Lowes, probably something I should have in my kit anyhow.

[bart998]

Yes, I leave the bearings in... just take-off the seals, spray them clean, blow out any debris or residual liquid with a compressor or even canned air for computers... re-grease with a quality lube like Park or Phil, put the seals back and go on your way.

Thanks, have a followup on the grease topic since you mentioned it.

Thoughts on Phil vs Park for sealed cartridges? Park is thinner, but heard lots of stories of people ruining their bearings (rusted/pitted due to moisture, contamination, etc). With Phil Wood grease though, it's plenty thick so might not be the best choice for sealed cartridges, especially if you really pack it in? As much as I love Phil Woods longevity, introducing drag is no fun. Never tried phil grease for sealed cartridges--did it work well for you?
