Is WD40 good for controlling corrosion at the ends of RCA connectors, component video connectors, S-video connectors? I live near salty ocean water. Got suggestions?

gold rcas should not corrode. I would keep the salt water away unless you live on a boat.

working in the specialist AV sector myself, the two main products we're working with are found on the net -here-and -here-, or you could go to your AV-man-round-the-corner and be advised/buy there

i don't see where he said there was pure gold on them. the caig stuff is great, but most of their stuff is still petroleum-based like wd40.

Off the top of my head, I seem to remember that petroleum based - and in particular WD-40 - lubes and protectants would, over time, attract moisture. I wouldn't think that attracting salty moisture would be a good thing.

I'm thinking that WD-40 would be good for only short term use.

Sorry, I can't quote my source. It has been too long. Nor have I gone looking before posting this. Just wanted to comment.

The original poster might want to find a forum for gun enthusiasts, or find a gunsmith local to him and ask. I bet these people would know what would be a good, long term protectant.

second thought
maybe my dentist could fix my car ...

he was open-minded enough to invest in music and video of all kinds , all to distract clients from his crueling activeties

and he bought his AV gear not at the supermarket, to assure he can have years of pleasure to look forward to

Since this doesn't make any sense, I'll assume that you are just being silly.

No he in the business of selling "high-end" cables and esoteric audio accessories. In the old days, these people used to be known as "snake oil salesmen".

These are the people who will attempt to convice you that "Brand A" of something is worth 10 times more than "Brand B" is, even if the two items have identical chemical makeups because "Brand A" has the right label. The fact that a gunsmith might have a chemical that does exactly the same thing that "buy buy" is looking for, it irrelevant. It won't have the esoteric label on it and it might only cost 1/10th of what the esoteric brand does, that's what matters. If you don't have the brand name and pay a lot, it can't be good.

Give me a break.

It's funny, I all the time I've spent in $500 audio/video finishing suits, I never once saw any of these high-end cable or met an engineer who thought they were anything other than horseshit. Against the scale of the investment these places represent, an extra $25K for cabling would be cheap if it made even a fraction difference, yet you never see them.

The problem with engineers is that they only believe the numbers and things that can be proven. They are immune to the "hype".

the 'hype'-factor is indeed there
so yes, most of the truly expensive cables are sold solely on brandname
that's why I recommended Caig: no hype here, it has proven to be well up the task for the last years, and it's one of the cheapest solutions around

for myself (not being an engineer ...), the electronic gear is just a means of reproducing recorded music/movies as good as possible
I've learned to trust my own ears/eyes, so hypes are beyond me (but the truth is, they sell great, even if unadvised by me)
this is why I didn't recommend buy buy to use product X, costing way more than the Caig stuff, but hasn't proven to be anything better

Okay. Then how about silicone spray? Think this might be better?

while caig stuff runs about ten dollars and there's nothing wrong with it, wd-40 will work fine. they're all oil in a can.

the question "WD40 good for controlling corrosion" is not answered by temporary 'sealing' it with silicone spray or 'oil out a can': both will dry out and leave a residue possible to make the signal worse after time

seems more alternatives are wanted?
try regular cleaning of all contact with pure alcohol

Which, as I understand it, attracts dust - which then attracts moisture - which defeats the purpose.

Granted, this is a very slow process. WD-40 _is_ probably the simplest, most readily available solution. I'd probably use it in this case. :) He just needs to know that he might have to re-apply it in time.

I wonder what would happen if he painted the connection with something like clear fingernail polish? The idea being to seal out everything.

I'm with you in this completely. No need for re-applying with Caig though: what is left as residue will form a conductive 'innner-layer' in time.

And I don't even work for Caig, or the linked web retailer. Maybe I've to change my id from pinc_noiz to pinc_caig ...?

the question was will wd40 work to control corrosion near saltwater.

the answer is yes. caig stuff is fine, but he wasn't concerned about potentially improving conductivity. some isopropyl booze to clean it and some $2 electronics lubricant at radioshack is ideal about 1/5 the price of the caig solution and every bit as good if that's what he's looking for.

The WD stands for 'water displacement.' The stuff they sell is the 40th formula which worked the best. WD-40 has lubrication properties which you don't need.
Buy some good cables with gold-plated connectors. Gold coins raised from the sea bed after 200 years under water still don't show any corrosion.

It doesn't attract dust, which eventually attracts moisture?

bud's correct about gold not corroding and if it ocntinues to be a problem i'd take his advice and get some new cables that are actually made to spec. nothing fancy, just real gold plating. i was thinking more about how to solve it without investing in things not at hand.

willywilly, you cannot be serious. wd40 is used all the time in marinas. in fact, i've got a can in front of me saying it "displaces moisture" and "protects against corrosion". which it does.

Sure I can.
No doubt. I wonder what else the use too. :)
As a matter of fact, marina types would be good ones for the original poster to inquire of. They install electronics, etc. on boats - it would be interesting to know what procedure they use to protect from corrosion.
Yes. Many moons ago, I've used it many times, spraying out wet distributor caps to get a car started. Worked great.
As any oil does. But - - that wasn't what I commented on.
I commented on how long it would do the job, and gave the reasoning behind it, as it was explained to me. Since you haven't replied to that question, I guess you don't know the answer. No problem - it's not a big deal. :)

1] it would be interesting to know what procedure they use to protect from corrosion.
2] used it many times, spraying out wet distributor caps to get a car started. Worked great.
3] As any oil does. // how long it would do the job //

1 >> electronics in moisty environments are best installed using dry sealing solutions (no oil based, as they stay, uh, oily)

2 >> where's oil can't be water

3 >> an oily solution does protect against corrosion, till the moment it dries and attracts moisture (when it will start doing so is fully dependent on the environment it's in; when it's very warm and/or dusty it will dry quickly)

>> nothing fancy, just real gold plating

to keep prices low, and gold plate it, is the reason those cables wouldn't have any plating left in the shortest of time, because the plating is thinner than thin : you get what you paid for
sorry, gold plated connectors are a perfect answer on buy buy quest, but as he pointed out he's not in to spending lots of cash:
having cables with connectors that really do connect is OK
using a dry cleaning solution to clean regularly is better
any solution that cleans and protects on the long run is still better
