Electrical contact cleaner?

[MidOH]

Make sure it's non chlorinated contact cleaner. Chlorinated may roast plugs and plastic.

Would it be wrong to use a contact cleaner from HD and then follow up with a degreaser, like Simple Green Extreme or Blue Gold?

Other way around. Simple Green followed by contact cleaner. Simple Green conducts electricity very well, and routinely screws up sensor readings on engines and generators.

Believe it or not, plain old wd40 does work good on many types of connectors.

The usual practice is to ensure that everything inside the loop is as clean as possible because it contains the gas you breathe. As pressure increases with depth, so does the partial pressure of whatever chemicals you used to clean / lube inside the loop.

There is also a practical aspect. If your supplies are suitable for O2, then you don't need to worry about mixing in non-safe components. That's one of the reasons why people may choose to use only O2 safe lube in places where silicon could work.

Yes, I know all that and that common sense (I hope ) but my point was there is no need to focus on the O2 cleanness if it is clean to breath.

My rationale is as follows: Remove grime first a questionable contact cleaner, then use an O2 degreaser to remove questionable residue. So yeah, you'll lose some lubrication provided by a contact cleaner but will be safe from inhaling bad stuff.

I am having connection issues with my Poseidon Seven and am wanting to clean the contacts in the fisher cables. I can’t get Deoxit on Guam since they won’t ship by air. Home Depot has cleaners made by WD40, CRC, and Klear Concepts. Would
any of these be OK on a rebreather? Any one better than the other?
Thanks!

Here are the Safety Data Sheets for the products; Klear does not seem to have one, and Deoxit's is not very informative, and their info says Deoxit Gold has only 0.5% cleaning action.

They are not the crappy Fisher connector version on the Se7en. A non- residue contact cleaner will work fine (as long as it won’t attack the plastics). Don’t over tighten the four connectors on top of your E-module and make sure that each female connector’s two O-rings are clean and very lightly lined.

Don't know anything about rebreathers, but I use 100% Alcohol to clean electrical contacts in devices: it quckly evaporates and leaves no residuals. If 100% Alcohol is not available, 96%-99% is okay.

Just not the 70% which is used as disinfectant as it evaporates slowly (hence more time to disinfect effectivly).

Is good cleaner for surfaces too, for example prior to gluing, clean lenses etc.

I climb up on the roof open the antenna electronics box and splash phosphoric around then water
Actually I like to sploosh phosphoric on everything, for rarely any deleterious results, only the best
Don't they splash phosphoric around inside tanks

Look at this product. I have used it for years, It is in a small bottle with an applicator tip.
