Blue Shower Electronics Cleaner

by kevinwfs413 In reply to Electronic Parts Cleaner

When I was working doing disaster recovery for PC and electronic equipment we used Blue Shower which is a Non Conductive Cleaner for getting rid of smoke and water damage on the mother boards and peripherial cards.. plus the old fashioned pencil eraser and a lint free cloth to clean contact points in the ISA and PCI slots.

If the system was sumberged with the power off <Fresh Water> and you clean and dry the equipment thoughly (all slots, CPU, power supply> you have a 40 -50 % chance of getting the system up even if its just for a very short time.

Water recovery. of elctrical goods

by michael_orton In reply to WD40?

Any electrical goods can be washed, even in a dishwasher. BUT you MUST dry them before switching on. Fred langa www.langa.com had an article about a year back.
Floppy drives mother boards etc could be recovered as a last resort using a dishwasher!
But they must be dissassebled and dried.
And keep clear when first switched on!
Nearly all white goods can be washed, dried and reused.
Its an old wives tale that electricity and water don't go together. Many times white goods and electronic are needlesly thrown away when a hoze would recover them!
Wash, dry, plug in, stand well back.. switch on
will work many times... if you are very careful.
But don't toutch them until they are working properly and the outer bits must be earthed.

Contact Cleaner Not WD40

by james.schenck In reply to WD40?

WD40 is great stuff but not for "all" computer parts. I do agree, all units should be broken down to its components. Contact cleaner is the way to go. Some say trichloralethylene was great but it is toxic if used the wrong way. There are other cleaners like Electro Cleaner and others that should be a better fit than WD40.

WD40 ARE YOU CRAZY

by wlbowers In reply to WD40?

WD-40 while it has cheerleaders all over the world
should never get near electronic components. It does
not evaporate. Anything that is not flushed away
remains suspended in the oil residue. Great soup huh.

WD-40 contains
Aliphatic Petroleum Distillates
PEL Petroleum Base Oil
LVP Hydrocarbon Fluid
Carbon Dioxide

I have been in electronic and computer repair since '69.
I was trained by the USMC. Part of this training was
equipment recovery.

Open it up. Pull the hard drive and set it aside.

Now take a garden hose and thoroughly wash the
beast out. Don't worry it's been under water for how
long?

You want to get as much of the gumbo soup it's been
sitting in out.

Now dry it out. First take compressed air. No not the
cans, from the garage, and **** it out.

Now some heat. We take a 500 watt halogen lamp and
put it about 18" from the open side of the computer. Put
a thermometer inside the case and move the light back
and forth until you get the temperature up to 100
degrees. Put a blanket over the case to retain the heat.

You have to get the moisture out of the coils and
transformers.

Yes it can take it. Most computers have a storage
temperature of 120+ degrees.

Leave it a minimum of 4 hours.

Now take a contact cleaner like blue shower II. You will
notice on their home page they show a can spraying a
computer motherboard. Buy the big cans, several.

http://www.techspray.com/

Start at the top and flush down. Don't be skimpy you
are flushing the remains of all of the crap, literally.

Clean the hard drive with blue shower. DO NOT OPEN
IT UP! Spray a rag and wipe it down.

Been There and Survived

by lorenzend In reply to WD40 ARE YOU CRAZY

The only additional notes I would add that I used to make this successful was that while it was drying and after it dried, I used an electronics brush and compressed air to get out any residual. Key is making sure that all contacts are clean and all circuits are dry before you assemble and plug it in. I also turned it on before I put the hard drive in to make sure it would get to post. If they did, then I added the hard drive. If they didn't, the hard drive was still available to use in another computer.

Water as a cleaner

by tony.maine In reply to WD40?

Dont use strong organic solvents like ketones, sulfoxides, nitriles and so on you'll probably damage seals and components. Dont use any solvent which isn't really pure - it might leave a residue.
If you have to use a dishwasher, rinse everything in distilled deionised water afterwards and let it dry completely before switching on.
As a final resort if the machine still won't boot up you can probably take the drives out and install them in a known good machine and see if it recognises them. Then you can get the data off separately.

WD40?..not a good idea

by michael.paparella In reply to WD40?

There ia a product called Corrosion Block that was origionally designed for the commercial market and what is used for electronics exposed to salt water. In the ad that I saw several years ago there was a picture of a working television sitting in a container of this stuff. Having used the product I can't say enough about it, but read for your self. Google will bring up plenty of links or you can go to this link http://www.nocorrosion.com/corrosion-control.htm. Don't let the price scare you, you'll never use anything else once you try it.

Cleaning hardware

by russ_it@millweb In reply to Good luck

I agree Monitors Scanners and printers are probably not worth the time and aggravation. Rom Drives and any pc boards are more likely candidates for a successfull result but you must use pc board safe solvents - check carefully for compatability before using.

Using a dishwasher

by aidplus In reply to Good luck

While I wouldnt suggest this for all parts, a fast wash in a dishwasher, minus the harsh detergents (Clean out first by doing a couple of empty washes and removing anything in rinse dispenser and detergent dispenser) The motherboards wouldnt be out of specs on low heat nor would the power supplies if opened up. It will certainly give it the correct treatment, followed by a distilled water wash. And a dry out in warm area. I was going to suggest hanging it out on the clothes line but that may be a bit too far out...(grin!)
Works for most bulk circuit boards...
