Coca Cola Gas tank experiment results

HOLY CRAPOLA!!! Why didn't I think of that???

Of course at this rate it will freeze on contact if it gets any colder around here...

But just think - if I still have to resort to the blow torch, I'll have a nice yummy caramel coated engine! Engine Brulee, even!

Hmmmm, would that qualify as a hot lick? LMAO

i dont know if this is relevant or even usefull for your usage

but tomato ketchup or sauce as we say in england has very good cleaning propertys it sure beats coke and is lots faster acting
when theirs been a pan badly burnt splash some tomato sauce on and leave a min the rub off usualy gleams like new
also makes pennys like new in a few seconds

i recently used tomato sauce to remove tarnish on my exhaust lol

Jeez, I've just spent eons removing the oxides and polishing my cylinder and head fins with dremels and wet and dry sand paper. I obviously overlooked the posibilities of using coke or tomatoe ketchup/sauce.
I'm shattered. Pass the beer.

I'll bet ketchup is great for all kinds of things. It's very acidic, as mentioned earlier, the sugar would probably temporarily seal the metal and it's thick enough to spread and not drip all over the place!

When I was a teen I worked in a restaurant that left ketchup bottles on all the tables. They weren't refrigerated and we were told to simply fill them with new ketchup when they got low. That meant there was a lot of old ketchup building up in those bottles... so much gas would build up in them that the tops would blow off and shoot ketchup everywhere when the lid was removed.
Wear protective gear!!! Ketchup can be dangerous in the wrong hands!

(I so have to try it)

Maybe your tank just prefers Pepsi! Ketchup is OK, But here in the south we like BBQ sauce. I don't recommend Beer in the tank like 49er suggested, that would be alcohol abuse!

You are mis-quoting me. I have never advocated cleaning out rusty fuel tanks with beer. We have a beer over here that many refer to as tasting like rusty water. I guess it would'nt be abuse if you would'nt mornally drink that brand anyway.
An overproof liquor would probably work better, but that really would be alcohol abuse.
I guess if it were mine, I'd use a couple of handfuls of small stones mixed with kerosine and shake the tank violently for 10 minutes or so. Have a beer, then drain the rusty kero and stones out, and spend the next hour chasing the last of those pesky stones out of the filler. Ideally a sealant should then be used to prevent the metal re-rusting over the following months.
