Default Electroloysis burning up

I found a few 9v charges so I was using them for cleaning some old spoons and they work well but they keep burning out on me. Do I no have enough voltage for something that large? I also need to leave them on for a while so I thought that could be a problem too. Would appreciate the input. Thanks!

make sure the two items aren't touching each other. And you should be using the small alligator clips the big ones don't seem to work as good, and last use salt & some lemon juice hope this helps

Thanks, I've done all those things but still have trouble.

You're drawing too much current and overloading the chargers.

Here's what I'd suggest. First, start with distilled water. It's pure and has no additives. Place the item in the water, connected to the charger like usual, and turn on the voltage. You should see no bubbling. Now, add a very small amount of the additive you are using to make the electrolyte, baking soda, lemon juice, whatever. You should start to see some bubbling. It should take only a small amount to get things going. Once the bubbling starts, you should be all set.

Note that as the water evaporates, the electrolyte will get stronger, allowing more current to flow. You'll need to dilute the solution to limit the current then, otherwise, it'll overload the charger.

Another option is to get a higher current supply, but you may be OK doing what I described above. Good luck!

I thought baking soda would neutralize the action (at least I thought I read that) but I am far from an expert on this subject?

I've just been using salt with some lemon but I can try baking soda as well.

Baking soda can be used in the distilled water to form an electrolyte.

Perhaps what you read was to use baking soda to neutralize the effects of lemon juice being used as an electrolyte in an electrolysis setup? Lemon juice is acidic, baking soda is alkaline. After an object is taken out of lemon juice, baking soda can be used to neutralize the acidic effects.

BTW, I'm not an expert on the subject either.

Hi, have you considered using a fuse to prevent burning up your power source? Another member of the forum sugested using a rheostat to control the current. I use both. Depending on the output of your power source, components (fuse, fuse holder, and rheostat) should be reasonably cheap. Probably under ten bucks at Radio Shack.

This is a good thread. It provides a lot of useful information that goes with the other Electoloysis thread at the top of the forum.

I just made it a "sticky".

my question is why does my grounded steel in the electrolisis setup start to decay and pit and break is my current too high? or is my solution to strong? i use the powder that came with the machine from my grandpa a long time ago my dad gave it to me and i thought i have no use for this then i started metal detecting and rememberd i had it. what should i do about the metal plate in there that is falling apart. please help me understand this.

the grounded stainless steel is your "sacrificial" transfering the currentto allow the electrolysis to occur... it always will corrode. I use cheapo stainless steel spoons from the dollar store, you get 2 in a pack for a buck and they last quite a long time...

The easiest way to clean coins is to use 2 AA batteries and a light bulb. Set the coins in the washing soda solution and set up the DC circuit so that when the light is in line on the (-) side. The light will come on when done cleaning or you can stop sooner.

Not sure why no one said this sooner but you are not supposed to use SS with washing soda. Whatever gas it gives off can kill you. I was told it is the same as what Germany used in WWI.

I have done 30+ guns and hundreds of coins. Just keep and eye on them and you will not get in trouble or ruin anything. I burnt my fair share of chargers up cleaning axe heads and tools. Now I just use batteries or a small 250mA power supply I built back in college.

When you put a flame to R12 refrigerant it make mustard gas(ww 1) is what we were taught in automotive school.

I believe your solution has too much resistance..thus the burned out charger..9v is fine but you should be using distilled water and sodium carbonate..not sodium bicarbonate.. I'm not saying other solutions won't work, but sodium carbonate and water make a true electrolyte..true electrical conductivity..use one teaspoon per 5 cups of water for a mild solution..up to 2 teaspoons maximum...dissolved completely..

Resistance.. I told you all..look it up for God's sake..flipping too much resistance in your solution

Ummmm, Joe? You're thinking backwards. The burning out of the supply(s) is due to too much current being demanded by the process. What that suggests is that there is not enough resistance, (to current flow), to make the power supply last.
(Low resistance = high current flow, high resistance = low current flow.)

What is really needed here is a current meter. Hook up the circuit, with the meter installed, then start adding your washing soda until you get a current flow indication that is compatible with the supply's indicated rating. If that requirement can't be met, then you need a bigger power supply.
I suggest an automotive battery charger, with a battery for your supply. This way, the current meter is already in the circuit, in the form of the charger's meter. The battery, (even if it's dead lawn tractor battery), will act as a filter/buffer for the overall circuit.

Umm..yeah ...a highly conductive solution will Max out your charger.. I gotta stop posting when I'm half asleep.. I stand corrected.. I wiped my butt before I crapped..
