Engine rust

TickledPink

I heard that Rolls Royce clean their engines with Coke. Has anyone tried this on their boat engine? 🙄

Break out a wire brush and hit anything loose. Spray matching spray paint and do it again next year

Coke does eat corrosion 

LaRea

Haven't tried using Coke.  I used a wire brush and POR-15 when I did the engine room reno.  That stuff works as advertised.  

PickleRick

POR is amazing stuff.  I've wondered how well it would work on aluminum fuel tanks for preventing corrosion.

Wow, that's a really expensive way to deal with rust. Might be cheaper to replace the motor.

PickleRick

Ever use coke on battery terminals?

TickledPink

POR is mega expensive but it does what it says on the tin so is it worth every penny?

LaRea

Yes, POR is expensive.  Also, once you open the can, you can't store the leftovers.  That's why they offer those really small cans.  But it works -- stops corrosion and looks great.

I've had pretty good success saving leftovers by putting a layer of Saran wrap on the top of the can before putting the lid back on - and making sure the lid and lip are fairly clean. Keeps the lid from sealing itself to the can. Lets me get two or three uses from a small can.

Got to be cheaper than coke!

     Coke is free when you find it floating off the coast of the keys.

Tip: use diet so it doesn’t get sticky. I cleaned up some chrome wheels with coke back in my high school days and it works. It’s the phosphoric acid that dissolves the rust. Makes you wonder what it’s doing to your insides. That’s why I stick to water and beer, wine or liquor .

Yea, never a big coke drinker...

I've never had the need to purchase feminine products, like diet soda.  But it's one I'll definitely remember

Coke contains carbonic acid, like many soft drinks.  The carbon dioxide they inject to make it fizzy, reacts with water to make carbonic acid.  It is in fact an issue in the ocean, with respects to coral reefs ... as CO2 increases in the atmosphere, it reacts with ocean water to make carbonic acid, ever so slightly decreasing the pH of the water, to make is a bit more corrosive, which damages coral reefs.  In pop, that carbonic acid is a much higher concentration ... so it will corrode certain scale and even some metals.

I love it!  I haven't heard anyone call it pop in a long time.  (I moved from OH to MD about 30 years ago).

Thank you Mr wizard!!!

All that Coke, and Hunter Biden has a CLEAN record still.  It must really work wonders

Old funny comment- “l don’t do coke, I just like the way it smells”

rasbury

So, all heard I'm sure that the investigator that has been delving into hunter Biden was appointed special concil to investigate further, after 5 years of investigation to come up with a gun charge and tax evasion. Perhaps this will put an end to it. I'm sure they will look at jarred and Ivanka walking away with 2 billion from the Saudi government next...

Hunter smokes crack...no way the coke is his unless he has a very generous buddy in DC
