WARNING: Wear protective gear during this process. All skin should be covered — long pants/shirt, work boots, gloves — and eye protection and filtration mask are very important because the reaction of muriatic acid and rust gives off extremely harmful vapors. If spilled, muriatic acid can be neutralized with baking soda. When working with these chemicals, make certain that you have ample ventilation. It’s good to have a fire extinguisher handy as well. electricity jeopardy 4th grade Always dispose of solvents / hazardous chemicals responsibly, please. And, be safe. An alternative method of using muriatic acid is explained (with pictures too!) in the blog post linked above.

WARNING: Wear protective gear during this process. All skin should be covered — long pants/shirt, work boots, gloves — and eye protection and filtration mask are also a good idea. Although phosphoric acid used for de-rusting tanks is somewhat less insanely toxic than muriatic acid, it’s still not something that you want inhale or have spilled on you. If spilled, phosphoric acid can be neutralized with a bicarbonate solution, such as baking soda. When working with these chemicals, make certain that you have ample ventilation. It’s good to have a fire extinguisher handy as well. Always dispose of solvents / hazardous chemicals responsibly, please. And, be safe.

Oxalic acid (wood bleach) can be a cheap safer alternative to muratic / hydrocloric acid. It gives similar results to phosphoric acid , but will flash rust some if you do not neutralize it and spray the tank with wd-40 when you are done. I used 4 tablespoons per gallon of water and let it soak 24 hours. Follow the naval jelly method and it will work out great.

This product can be used to clean rust from the inside of a gas tank because it contains phosphoric acid. This can be accomplished by completely first de-greasing the the gas tank with a commercial de-greaser or very hot soapy water. Flush the tank with water after de-greasing. Next you plug the hole where the petcock goes, and then fill the tank with the etcher (make sure you mix the etcher with water at a ratio of 1:1). It must be watched carefully so that it doesn’t eat through the good metal. Next carefully drain out the etcher and rinse the tank with water. Next fill it with a solution of water and a small amount of baking soda to neutralize the acid. After 15 minutes, rinse the tank with water again and continue rinsing until the water you pour out of the tank is completely clear. At this point it is important to make sure the tank has no more water in it. This can be accomplished by getting as much water out as possible, adding WD-40 or rubbing alcohol to the tank, and rinsing it out with gasoline. Immediately fill the tank with premix to prevent further rusting.

Vinegar can be used to clean rust from the inside of a gas tank because it contains acetic acid. This can be accomplished by filling the gas tank with water and then draining that. Next, plug the hole where the petcock goes, and fill the tank with the vinegar, leaving it in overnight to dissolve the rust. After pouring out the vinegar, rinse the tank with water. Next fill it with water and a small amount of baking soda to neutralize the acid. hp gas online After 15 minutes, rinse the tank with water again and continue rinsing until the water you pour out of the tank is completely clear.

I went with the vinegar/salt combo (gallon of vinegar and 1.5 cups of salt) for a mild acid that would slowly eat away at the rust, for less $$$. I emptied the vinegar out every day to take a picture and to flush it out, and only adding a new gallon on day 3. It took about 5.5 days, but it looks pretty damn good for only spending $6 on two gallons of vinegar and a bottle of salt. When I rinsed the tank, I put lots of baking soda to stop any acid. Actually i added to the vinegar to make it foam and I capped the top of the tank so it would bubble itself out of the petcock. I think this may have loosened any lingering rust because there were a few flakes that floated out. I then rinsed with water and soap several times followed by a few wishes of fresh fuel. gas station I did not see any flash rust before I topped it off with pre-mix.

The Works toilet bowl cleaner is a cheap, readily available, fast, and effective product that will remove rust from your gas tank. However, the main ingredient in The Works is hydrogen chloride. Hydrogen chloride + water = hydrochloric acid = muriatic acid. If you want to use The Works, scroll back up and read the muriatic acid section above. Already read it? Read it again. The following instructions should be considered an addendum to the much more complete directions above.

Electrolysis is a technique for returning surface rust to iron. The process actually alters the tank wall on the molecular level removing the oxygen that has oxidized (rusted) the tank. This method has advantages over old standbys like vinegar, Coke, muriatic acid, naval jelly, wire brushing, sand blasting, etc. because those methods all remove material to get rid of rust. These other methods also remove un-rusted material. The electrolytic method removes only the oxygen from the oxidized metal by returning surface rust to metallic iron, rust scale is loosened and can be easily removed. Un-rusted metal is not affected in any way.

• Attach the battery charger NEGATIVE lead to the part and the POSITIVE lead to the electrodes. Do not get this backwards! If you do, you’ll use metal from your part to de-rust your electrodes instead of the other way around -the positive electrodes are sacrificial and will erode over time. That’s how the water becomes iron-rich. THE POLARITY IS CRUCIAL!! The iron or stainless electrode is connected to the positive (red) terminal. The object being cleaned, to the negative(black). Submerge the object, making sure you have good contact, which can be difficult with heavily rusted objects. Get it backwards and your object will be relentlessly eaten away! Make connections on a part of your electrode that protrudes out of the solution, or your clamps will erode rapidly.

Within seconds you should see a large volume of tiny bubbles in the solution – these bubbles are oxygen and hydrogen (very flammable!). The rust and gunk will bubble up to the top and form a gunky layer there. More gunk will form on the electrodes – after some amount of use, they will need to be cleaned and/or replaced – the electrodes give up metal over time. That’s why re-bar is such a nice choice – it’s cheap and easy to get in pre-cut lengths.

• This process produces highly flammable and explosive hydrogen gas (remember the Hindenburg?), so do it outside, or in some other well ventilated area. Hydrogen is lighter than air (like natural gas), so it will collect near the ceiling – not sink to the floor like some other flammable vapors will (like propane and gasoline). If you have open flames near this (Hint: gas appliances like water heaters and furnaces have pilot lights!) you will most likely severely injure or kill yourself (and others near you) and become a contender for the Darwin Awards in the process.

Did my tank by itself. Clamped one lead to the petcock, made an anode that fit in the fill spout (Left room for flushing around it) with the other lead attached to it. Filled tank to the top with electrolyte solution. "cooked" it for about 24 hours. Flushing the fill spout area frequently and cleaning my anode with a wire brush about every hour. – Worked great. When done I flushed with clean water and a bunch of nuts rattled around inside. then dried it with a blow dryer. la gas leak After I poured a bunch of 2 stroke oil in and rolled it around to coat everything at least till I get it full of gas.

Evapo-rust and Rust Release are "green" rust removers because they are not harmful acids and they do not create harmful fumes. It can be dumped out onto gravel when you’re finished using it, which can save you the hassle of storage or paying to remove the acids stated above. The other good thing about Evapo-rust and Rust Release is that it is only designed to eat rust and not metal, so you can leave it in your tank for over 24 hrs without burning a hole through the metal. The downside is that it was necessary to leave it in the tank for 36–48 hrs to get it about 90–95% clean.

I followed the same steps stated above: Drain old gas, remove petcock, de-grease tank and do a post-de-greasing rinse, use Evapo-rust or Rust Release, fill it with nuts and bolts to knock off loose rust, wash it out, fill it with Isopropyl alcohol, drain that, flush it out with gasoline a few times (drain and store). After all that, buy and install a fuel filter as a precaution.

It went from thick rusty sludge to barely any sediment running through my fuel line. You can buy Evapo-rust at Autozone (check their website for other retailers too), but the employees don’t know that they have it, so tell them it is probably locked up. It also may be in the paint aisle. It is roughly 10-13 bucks per liter, and usually comes with a 3 dollar mail in rebate. 3-4 liters Should work, but depends on how big your tank is. Also available at Amazon.

J.B. Weld is a welding substitute/epoxy. When cured, it is water, petroleum, chemical and acid proof. In rare cases, the petcock may take an impact which may break the weld on the threaded tube jutting from the gas tank. When this happens, the petcock appears to be leaking, or gas leaks from inside the frame and onto the engine. Because there is no way to weld on or replace the tank, it must be repaired likewise or the frame replaced. Removal of all gas and application of a degrease compound is essential in preparation for use of J.B. Weld. While it may be impervious to gas after curing, before cured, gas and oil will compromise the epoxy, grasp on the tank wall and crack. From personal experience, degreasing and riding around for about a month (with external tank) was enough to clear out and clean the tank. A generous amount of J.B. Weld should be mixed. Rough the inside of the threaded tube as best you can with a dremel tool for best adhesion. Bending a long wood screw (torch applied) at a 75 to 90 degree angle will allow you to rough up somewhat the inside back of the tank wall you can’t see and be useful later. Pack the epoxy down inside the threaded pipe jutting from the tank. Once this is done use the bent wood screw to smear the epoxy all around the inside back of the tank where the tube is welded on. Before the epoxy cures, plug the tube with an assistants finger or other and create a seal around the fill hole (where the gas cap is) and use an air compressor to create pressure in the tank and hopefully blow epoxy into the cracked weld. Afterwords let cure for suggested time on box before applying pressure to the threaded tube or filling with gas. gas in dogs stomach THE EPOXY WILL HARDEN AFTER FOUR OR FIVE HOURS BUT DO NOT FILL WITH GAS UNTIL FULL CURE TIME HAS ELAPSED. Hopefully when you fill your tank up it won’t leak. If not, repeat the process, buy a new frame or get happy with and external tank.

I don’t want to crap on your advice, but JB weld does not work in any application where it is exposed to gasoline no matter how well you clean it. I tell you this from experience. gasoline dissolves it no matter what the manufacturer claims. I don’t think it is the ethanol either. the only successful patch to a gas tank using an epoxy resin was where I plugged the hole with wax and then used JB weld over it. it lasted a couple of weeks. best advice is to weld it or use brass solder if it is very thin iron. and don’t be afraid of it blowing up. let it dry out overnight or blow some air through it to dry it and get the vapors out and it will be fine. test it with a match or a torch first if you want to, and keep the gas cap off.

For plastic gas tanks with a leak I have used a soldering iron or a hot flathead screwdriver to melt a hole shut. I also used the technique on a leaky plastic canoe once. another useful technique is to use a filler plastic. I have used ice ream pail lids cut into strips to patch gas tanks. I lit one end of the strip on fire and let it drip over the crack. It worked great on more than one leaky tank. But one time it didn’t. I think there was some kind of incompatibility in the two kinds of plastics. it’s worth a try.
