Have a coke

[david12171951]

Ok speaking of rust. I have seven 4 x 4 11 gauge metal post that have rusted mildly. They are vertical and stand about 12 foot tall and can access all 4 sides safely. Now how can i remove the rust with out me climbing a ladder. Being partially disabled is the reason for no climbing. I would like to do it with chemicals or such. Do have fresh water available, also can borrow a high presure washer if I just have too. ( hate to borrow tools!!!) Help please, yes it is hotter then Hades here in South East Texas also. Thanks David.

Have you considered some of the paint-on coatings such as "Naval Jelly"?

They're supposed to take any FeO2 and chemically change it into a permanent non-rusting coating. I tried it once on a large, old, rusted framing square, and it seemed to work well. Numbers were even still clearly legible.

All that's required is to remove any loose scale/surface rust beforehand; a thin coating of rust left intact is actually desirable.

A ladder may still be necessary... but it's an easy application that a "volunteer" could handle....

It's been about 30 years since I used any naval jelly, but it worked well. I found an old rusty 10 gallon milk can half buried in the mud on a cousin's property. He didn't want it, so I used naval jelly, then painted inside and out and made an umbrella stand of it. When I retired and we went to full time RVing, my wife gave it to her best friend who lived 2 doors south of us. She still has it just inside her front door.

...And remember, that's NAVAL Jelly, not NAVEL jelly!!:laughing::laughing:

Oops. Couldn't resist!

Can you tell school's started and I'm swarmed with middle schoolers all day?:laughing:

Another use for Coke is on tires. We used to use it on inspection day at the fire station on the fire trucks. It made the tires black and shinny like Armorall does.

I'm picturing Tony Stewart putting Coke on his tires and drinking his Armorall.

Coke cancels battery acid too, just in case you have one to blow up. It can stop acid from eating your clothes and shoes..

Coca Cola is acidic. It would have to be a base to neutralize Sulfuric acid. If anything, it's diluting the battery acid but in a pinch, diluting it with anything that isn't in itself harmful is much much better than leaving it full strength.

You have to get pretty deep into chemistry to get that an acid is relative to what environment it's in. Some weak acids will actually neutralize other stronger acids. How a complex acid behaves isn't dependant on what a litmus paper tells you. I think one of the the acids that is in Coke is actually carbonic acid. It's the acid equivalent to carbonate which is the active component in sodium carbonate, otherwise known as baking soda.

Coke will likey neutralize an alkaline as well as an acid.

That is why I like to use Coke over baking soda on my battery terminals. The coke can seep in between the post and terminal and neutralize corrosion. Then rinse away the coke with water.

Now I thought of the naval Jelly but for 7 24ft. posts like I have it would take a 5 gallon bucket of it probably, well 2 or 3 gallons. This would be kind of cost prohibative. Some one mentioned a solution of Muratic acid and using cheap 4 inch paint rollers to apply, then wait and rinse thouroughly. The use same type rollers to paint post. Just still did notknow ration of water to acid. Any thoughts along this line?? Dave. P.S> do understand that coplete slicker suit would be needed with full face shield and so n about the safety stuff involved.

I had a Saturn I sold a year ago or so when I had enough with GM. Anyway, it started burning oil very badly at 35,000 miles or so. I am talking a 1 qt every 600 miles. I took it to GM and raised he11 but they said it was in tolerance. Stupid thing only held 4 qts so you were adding a qt every week and a half.

Anyway the mechanic at the dealer told me he had great success taking the plugs out, turning the engine over till all 4 cylinders were even, pouring 3oz of Coke and 3oz of diesel fuel and letting it sit for a few hours. After that time take a turkey baster with a hose on it and get out all the mix you can then turn the engine over a few times with the plugs out to blow the rest out. Put the plugs in and run it for a 20 minutes then change the oil with Mobil 1. He said to only use Mobil 1 because it had he highest detergent package in the industry. Keep that oil in there for 500 miles then change it again back to your regular oil.

I was scared to try this so I just ran 10W40 instead of the 5W30 it called for and got the oil use down to 800 miles per qt. Ran it that way for 130,000 miles with no issues other than drinking oil like so many other GM's do.

I can see how this would clean things up, especially the rings which he said was the problem.
