Thumbs down "Old gas" smell

Does anybody have a "magic formula" to get rid of the old gas smell in fuel tanks?
I put my Brownwall in the hot vat last night. Then this morning, when I opened the shop door, the fumes from the old gas residue in the cast iron base tank almost knocked me down!
I have heard of getting rid of a skunk scent with Tomato juice, but what will remove this awful stink? I've been smelling it for years, but there's GOTTA be somethin' to get rid of it.

Laquer thinner will desolve the varnish, it's available at automotive paint stores in 5 gallon bulk cans fairly reasonable, about $25 last can I bought. It wouldn't hurt to try chlorine bleach first, less hazardous waste.

Clean the tank thoroughly with acetone or naptha, rinsing it out several times and refilling with clean acetone or naptha each time until the naptha or acetone looks good and clean when you dump it out. Rinse with HOT water, then use compressed air or heat to dry it out as soon as possible. Then, coat the inside of the tank with a good quality gas tank sealer. The sealer will prevent the gas from impregnating in the pits in the cast iron.

WARNING-DANGER

WARNING - DO NOT PUT CHLORINE IN THE FUEL TANK _ EXPLOSION HAZZARD

Chlorine is an oxidizer - mix it with hydrocarbons and BOOM. DON'T DO IT

You are making things up again, pouring bleach into gasoline will not cause an explosion. I do not recommend doing it, there is no point.

The fastest way to dissolve gas tank varnish is hot caustic drain cleaner. Not drano, use the pre-mixed liquid hydoxide. Wear plastic gloves and face shield. Or take the tank to a radiator repair place and have them hot-tank it.

Hi David,
This is the hot ticket for eliminating fuel smell. I use it for effect at shows, but I've found that it eliminates the gasoline smell in the garage as well.

Summit Racing has a line of fuel fragrances that are used to reduce the noxious fumes associated with nitro and gasoline. It comes in about a dozen flavors such as Burn Out Blueberry, Rocket Cotton Candy and Cherry Bomb.

Get the little four ounce bottles, not the larger bottle that is intended for alcohol. Go to www.summitracing.com and search for fuel fragrance.

Rob

Gasoline has alcohol in it, alcohol make chlorine break down in to chlorine gas. Not good. However,alcohol evaporates and should not cause any problems if the tank is dry...i still would not do it, use a solvent

How about when the engine you just bought tips over in your ford explorer, and dead gas runs everywhere. Mind you this engine was tied, it just took a hard left and tilted over. It sure ain't easy to get rid of that smell!

The great thing about this forum is that you can get an answer to almost any question.Some times there is a big differance of opinion and here in this thread is one.I respect both opinions but I wonder who is right as to gas exploding when mixed with bleach.I for one am not going to try it to find out.

A local welding company used bleach to wash out the fuel tanks they welded, they did a lot of oil field welding, never had an explosion, I don't know their reason for using this, I would think detergent would have been better.

Clorox will rust bright iron or steel and right before your eyes. Take an ungalvanized nail, put it in a clear jar and fill it with Chlorox. Then just watch it.

Don't know about the gas smell. It seems like every tank I work on requires a different treatment.

Here is an excerpt from the aforementioned GEM article by Chuck Harris, November 1990:

So I got to talking with Jack Blair and Marvin Simon (two members of our club), and they told me to add some oil of wintergreen to some of the Liquid Wrench and shake well, then apply to the engine.

Now comes the fun part. Jack and Marvin told me that I should be able to purchase it at a local drug store. After five or six stops at different drug stores, pay dirt! The pharmacist did not look at me as though I was from another planet when I asked, "Do you have any oil of wintergreen?" He said, " Yes we do carry oil of wintergreeen. You are standing right next to it, it's on the third shelf on your right." He only had three 2 oz. bottles. I bought all three. I didn't know how much I would need to mix with a gallon of Liquid Wrench. Well, back home all three bottles go in to the gallon jug, shake well and applied. I did not notice any different odor right away, probably due to everything having absorbed the smell of the kerosene. Well that's enough of this for one night, I will see what it smells like in the morning. Next morning, what a difference it made. My whole shop smelled like peppermint! I can live with that! But it was the wife who had the final say. When I got home, my wife said, "I do not know what you did but it worked, I like the smell of peppermint better than the kerosene." With that in mind I did not care that the oil of wintergreen cost $2.29 per 2 oz. bottle. I would have paid anything to get the smell out of the shop because it was even starting to get to me.
