someone else will upload them, trust me. We just need to be sure you take pictures, cause everyone else will have the good sense to stay well away. We can put it up on youtube in your memory.

I got $5.00 bucks on toadie,....$5 bucks that he will grenade himself into a new realm!

 

My borther in law once thought like toadie, 5 years ago my sister gets the call that her exhusband had blown himself to smitherings in his trailor park home! He was a do it yourselfer, he mixed the wrong chemicals making himself some meth and WHAM!

 

I laugh til this day!

 

Edit: but to add, electrolysis hot tanking is all over youtube, I dont think it will work all that great, its not so much the risks involved, not so much the disposal of the hazardous waste, but just the mere trouble and time involved when its so damn cheap to let someone else do it.

You are kind of getting the processes mixed up

 

 

Hot tanking is done at machine shops and can use caustic or non-caustic chemicals

 

Caustic chemicals are only used for iron or cast iron (hard metals), aluminum and soft alloys need non caustic chemicals

 

Solvents and alkaline chemicals are considered caustic,

 

 

All you achieve by using a battery and a water tub with chicken wire is making a water heater.

 

You can buy a construction grade hot water hose and attach it to a water heater spigot to get hot water.

 

Use tide laundry detergent to remove dirt and grease.

 

 

Pressure washers at the DIY quarter car wash do not have the same PSI rating as the pressure washers you can buy at the hardware store to wash you deck or your driveway, they cost 50.00 to 150.00

 

 

Once you have the grime and grease off the parts if you have rust inside the water jackets of an engine block for example you can take the block (with the main caps and bolts) to a chemical hot dip. Usually a metal plating shop has an acid dip tank that will clean the block inside and out.

 

 

Soda blasting is a good way to clean aluminum and if any fine residue is left by the process.

 

The soda (baking /bicarbonate) will not damage the bearing surfaces or clog fluid passages as glass beads or other blasting media will.

 

 

When using electrolysis any salt or alkali that is used in the process needs to be chorine free (sodium chloride) table salt will release the chloride molecule and mix with the hydrogen present in water and create hydrochloric gas which is poison, for that reason Epsom salts are used to achieve the correct ph balance for the electrical (ion) current to travel.

You also need to be careful of the water source since hard tap water is softened with salt

By using chicken wire, any metal alloy present in the wire could be transferred to the part immersed in the tank.

yes, i did get it mixed up cause I was googling diy hot tank and what I did was the top results.

 

 

anyway, all the grease is gone, the paint just falls off, the part is clean. I gave it a rinse to wash off the residue, it feels clean to the touch, nothing is sticky.

 

Where there was a thick layer of oil inside the oil pan is now an exposed layer of rust. What can I use to cover it up? Any paint that will stand up? its not in a very reachable place.

Your supposed to dry it fast before it rusts. I would not paint the inside of the pan, too much risk that it can flake off.

I pulled it out and it was rusty. left it in the hot sun, its completely dry.

This is how it was after a rinse.

Guess for the rust I will scrape it off as much as I can and cover it up in a layer of oil. the underside will get a coat of por15

im really digging the goodwill dishwasher idea. cant believe i never thoughgt about that. then again i dont do that much cleaning of engines to justify bothering. for what little i do, pressure washer, purple stuff, carb cleaner and elbow grease works great.

 

as for that rust on the oil pan, now you gonna have to have it blasted to get that off.

Things dry super fast if you use very hot water to start with, it just evaporates a lot faster.

 

A rusty pan with the loose rust wont hurt the motor, oil will keep it from growing worse so no need to paint. OIl it now if it's a part you care about.

 

That's why I suggested mineral spirits, they just evaporate with no oily residue, and you can wipe clean any solids that are left behind (they just stay attached like dust). Nice thing about mineral spirits, you can let the crud settle out and pour it back into the container and reuse it over and over and over again. When you want to get rid of it, just mix it with your used motor oil and dispose of it that way. It's just a small chain hydrocarbon, just like oil and gas, so it melts greese and oil, but it fully compatable with it. It works like washing stuff with gasoline, but with out the dangerous flash point or aweful smell. It's about $4 a gallon.

A fine stainless wire wheel on your drill will clean off the surface rust.

You can use denatured alcohol to wipe it down after, but it too has a low flash point and costs around 4 dollars a gallon.

I use it to wipe down to remove any residue from using a degreaser.

 

Calcium, Lime and Rust Remover works too on surface rust but you still have to rinse it off, and be careful not to breath it of get any on your skin or in your eyes.

 

Hang it in the sun and paint the outside with some primer.

 

Another method you can use a propane plumbers torch or an electric heat gun and cook the paint off,

then scrape and wire brush but you want to make sure all oils and grease are removed so they are not spread around with the brush.
