Dirty inputs on back of receiver

Hi,

My receiver is about 6 years old. I have never had the need to use the multi channel inputs until now. I noticed they are a dull color and seem to have some sort of film on them. Can anyone recommend a good way to clean them before I attach the cables?

Thanks for any help.

I spray a little wd40 on a rag and wipe them off. As long as it isnt the plating coming off, I have seen this on some older avr's...

I'd imagine a little bit of rubbing alcohol would do the trick.

Unless you are a smoker, it is called dust. Just wipe it off. WD40 sounds like a very bad idea to me, but the rubbing alcohol will definitely work.

I would not use WD40!

IPA (rubbing alcohol) and Q tips would be fine. The higher the % alcohol the better and be sure it is dry.

If that doesn't work, you may want to check into Deoxit

I dont know why people would say not to use WD40, I learned about it as a contact cleaner when I worked a Emod mechanical, and when controls had moisture in them they had us spray them down with wd 40 and power them back up the next day, never failed...

Im not saying to douse it, just spray a little on a rag and wipe them off... If you have a can I wouldnt go buy a can just for that but I know a lot of people have a can in the garage so its an easy fix... Im sure alchahol will work even windex or a damp rag as long as you dont leave anything wet...
I wouldnt over think it...

But for people to say not to use WD40 like it will hurt something isnt correct...
After all its good for everything... I spray it on my bait, its the best fish attractant Ive ever used... Spray some in a pond and see the fish come up to the surface for it..

WD40 stands for Water Displacement #40. The product began from a search for a rust preventative solvent and degreaser to protect missile parts. WD-40 was created in 1953 by three technicians at the San Diego Rocket Chemical Company. Its name comes from the project that was to find a “water displacement” compound. They were successful with the fortieth formulation, thus WD-40. The Corvair Company bought it in bulk to protect their atlas missile parts.

Ken East (one of the original founders) says there is nothing in WD-40 that would hurt you.

When you read the “shower door” part, try it. It’s the first thing that has ever cleaned that spotty shower door. If yours is plastic, it works just as well as glass. It’s a miracle! Then try it on your stove top... Voila! It’s now shinier than it’s ever been. You’ll be amazed.

Here are some of the uses:

1) Protects silver from tarnishing.

2) Removes road tar and grime from cars.

3) Cleans and lubricates guitar strings.

4) Gives floors that ‘just-waxed’ sheen without making it slippery.

5) Keeps flies off cows.

6) Restores and cleans chalkboards.

7) Removes lipstick stains.

8) Loosens stubborn zippers.

9) Untangles jewelry chains.

10) Removes stains from stainless steel sinks.

11) Removes dirt and grime from the barbecue grill.

12) Keeps ceramic and terra cotta garden pots from oxidizing.

13) Removes tomato stains from clothing.

14) Keeps glass shower doors free of water spots.

15) Camouflages scratches in ceramic and marble floors.

16) Keeps scissors working smoothly.

17) Lubricates noisy door hinges on vehicles and doors in homes.

18) It removes black scuff marks from the kitchen floor. Use WD-40 for those nasty tar and scuff marks on flooring. It doesn’t seem to harm the finish and you won’t have to scrub nearly as hard to get them off. Just remember to open some windows if you have a lot of marks.

19) Bug guts will eat away the finish on your car if not removed quickly. Use WD-40!

20) Gives a children’s play gym slide a shine for a super fast slide.

21) Lubricates gear shift and mower deck lever for ease of handling on riding mowers.

22) Rids kids rocking chairs and swings of squeaky noises.

23) Lubricates tracks in sticking home windows and makes them easier to open.

24) Spraying an umbrella stem makes it easier to open and close.

25) Restores and cleans padded leather dashboards in vehicles, as well as vinyl bumpers.

26) Restores and cleans roof racks on vehicles.

27) Lubricates and stops squeaks in electric fans.

28) Lubricates wheel sprockets on tricycles, wagons, and bicycles for easy handling.

29) Lubricates fan belts on washers and dryers and keeps them running smoothly.

30) Keeps rust from forming on saws and saw blades, and other tools.

31) Removes splattered grease on stove.

32) Keeps bathroom mirror from fogging.

33) Lubricates prosthetic limbs.

34) Keeps pigeons off the balcony. (They hate the smell).

35) Removes all traces of duct tape.

36) Folks even spray it on their arms, hands, and knees to relieve arthritis pain.

37) Florida’s favorite use is: “cleans and removes love bugs from grills and bumpers.”

38) The favorite use in the state of New York WD-40 protects the Statue of Liberty from the elements.

39) WD-40 attracts fish. Spray a LITTLE on live bait or lures and you will be catching the big one in no time. Also, it’s a lot cheaper than the chemical attractants that are made for just that purpose. Keep in mind though, using some chemical laced baits or lures for fishing are not allowed in some states.

40) Use it for fire ant bites. It takes the sting away immediately and stops the itch.

41) WD-40 is great for removing crayon from walls. Spray on the mark and wipe with a clean rag.

42) Also, if you’ve discovered that your teenage daughter has washed and dried a tube of lipstick with a load of laundry, saturate the lipstick spots with WD-40 and re-wash. Presto! Lipstick is gone!

43) If you sprayed WD-40 on the distributor cap, it would displace the moisture and allow the car to start.

P.S. The basic ingredient is FISH OIL.

P.P.S. I keep a can of WD-40 in my kitchen cabinet over the stove. It is good for oven burns or any other type of burn. It takes the burned feeling away and heals with NO scarring. :)

Oh yeah, be sure the power is off and unit is unplugged before you try anything.

WD forty indeed is a "water displacer".

It isn't the WD40 that bothers me, but the residue that it leaves behind. That is not something I want on MY audio connections, fingers, high-gloss finishes, etc. If you use WD40 to remove corrosion, then I would recommend following up with IPA to remove the residue. So why not just hit it with IPA and be done with it. Or look into Deoxit, that was designed to clean electronics parts.

I would NOT use Windex. It has ammonium in it, that sounds like you are asking for corrosion to me.

I only need 2 tools, WD40 and Duct Tape.

If it should move but won't, then I use WD40.

If it shouldn't move but does, then I use duct tape. :D:cool::)

Hmm, I'm not saying dround this thing in windex and wd40 solution, wipe it down, it isnt going to cause corrision, I pump windex down hot rifle barrels to stop corrosion, do a google search its the best thing for cleaning corroded ammo... If you dont leave an moisture behind you will be fine... The coating the WD40 leaves behind is GOOD for contacts... I put dielectric grease on all my hot rod and chopper electronic connections and never have a problem... Spray a cracked cap with wd40 and it will stop it from arcing in the rain...

To the OP, this isnt "rocket surgery";) wet your fingers with your tongue and wipe the dust off... Then dry it with a tissue. Now Im sure someone will post here and say "a tissue, make sure it isnt coated with lotion or it will leave residue" LOL .... This is getting a little out of hand...

LOL. Sounds like a "cure all" salesman. Going to have to disagree. Just because it cleans things does not mean it is OK to use on everything. Regardless of what the product says it can do, ever seen any electronics manufacturer recommend this? Not likely.

It is a great lubricant and penetrant, and as such, you should never leave it on a painted surface on your vehicle - it will do exactly that and eventually peel the paint.

The only thing I use it for is squeaky door hinges and stuck bolts. Guess what, anything that it says this stuff will get out, most likely any other oily product will too. Butter and peanut butter can get a large number of the same stains/crap out too, why? Because they are oily and they penetrate the stain. I used butter to remove Liquid Nails from my hands after everything else failed. That stuff is pretty tough, but not tougher than butter apparently.

I use Deoxit on my electronics; it also leaves a slight residue. WD40 is not a dielectric.

Corroded ammo...hmmm I guess it depends how bad and maybe what type, but not likely to use it.

Deoxit was designed for electronics, so it is a safer bet.

On lab equipment in the clean-room, nothing but 100% IPA for me.

That's where I learned it too. When disassembling, repairing and reassembling highly sensitive medical electronics in a clean environment, IPA was the only thing we could use.

I wasnt implying wd40 was dielectric, just trying to show that grease isnt bad for electronics or metal.. And wd40 residue isnt going to hurt anything...

I thought the OP wanted to just get them clean with something he had around the house, not go hunting for Deoxit Gold, last time I bought it it was like $19 {small cans the size of you finger, lol} at radio shack... And I used it once, then the first can had no propellant when I went to use it again...

But anyway this has been discussed for too long already...

As far as windex its good for a lot of things too, watch my big fat greek wedding, the stuff works...
I was given a couple thousand rounds of 7.62x39mm but it was all corroded, one of the old timers at the range said to wash it with windex, I went home obviously had windex in the closet so gave it a try, AMAZING, then after doing some research seen it was good for hot fouled barrels to get rid of corrosion, and I just happen to have an M1 that gets really sh!tty inside, so I tryed it now I use it after every range visit and its perfect 10 years of it on the inside of a hot 50-70 year old uncoated metal barrel and no signs of rust...

Interesting, never heard that one. Not that I am going to run out and try it, but do you also routinely brush/patch clean the barrel?

FWIW, I don't use the spray Deoxit, I just use the liquid.

Dust??! I don't have any of that in my place. Not sure I'm liking the WD-40 idea. Think I might go with a little alcohol and a q-tip. :) Need to make sure I have nice clean connection for my new OPPO player

I clean everything after I shoot it, but the m1 is just a pain to keep clean, its old and worn, but fun to shoot...
I shoot the m1 a good amount when I have the ammo... Im trying to see how long it takes to wear it out...:cool:
I have a pretty modest 1911 collection too and one of my early colts gets the windex treatment once and a while... To put in perspective how much I shoot, last year I spent $16,800 just on .45acp and .556 rounds {I buy them in bulk around xmass time when all the sales are happening}. This year I am probably going to spend around the same depending on the prices... I mostly shoot my 1911's and mini 14's and ar15's....
