Evapo -rust for cleaning gas tanks.

Just curious if anybody has used this for cleaning a dirty rusty gas tank?

Re: Evapo -rust for cleaning gas tanks.

You can also use vinegar. Some people use rocks or a length of chain inside and rock the tank back and forth to help knock off the heavy rust.

You will want to neutralize it with baking soda water afterwards. Then dry it out, or add something like diesel to stop flash rust from forming

I don't believe they were coated but I would sure coat them if they are already out and getting cleaned.
I have used a couple of different sealers and have had great luck with them both.


US STANDARD FUEL TANK SEALER


POR-15® Fuel Tank Sealer was formulated and developed in our own laboratories due to the demand for a high-tech sealer impervious to all fuels, including the new Stage II fuels which have a high alcohol content. POR-15® Fuel Tank Sealer has superior strength and fuel resistance, and does not contain Methyl Ethyl Ketone, a highly flammable and deadly carcinogen (cancer-causing). POR-15® Fuel Tank Sealer is non-flammable and is environmentally safe.

I used CLR and a pressure washer, I had excellent results.

Muriatic acid and water works well. Lots of precautions to observe in its use and as above stop the rust from reforming because it happens quick.
