Evapo-Rust is effective on mild steel surfaces and will not affect PVC, plastic, rubber, glass, or non-oxide-based paints
Evapo-Rust is a highly effective rust remover that can be used on mild steel surfaces. It is safe for the user and does not affect PVC, plastic, rubber, glass, or non-oxide-based paints. It is also safe to use on un-rusted steel, brass, copper, aluminium, gold, lead, titanium, cast iron, chrome solder points, vinyl, silicone, cork, or wood.
Evapo-Rust is an excellent solution for removing rust from inside a fuel tank. Before using Evapo-Rust, it is important to drain the tank and assess the amount of rust. If there is heavy rust with flaking and debris, the tank should be washed out with clean water first. After draining and inspecting the tank, pour in enough Evapo-Rust to completely cover one side of the tank. Allow each side to soak for two to three hours, repeatedly turning the tank until each side has been treated.
Evapo-Rust contains detergents that penetrate oils and dirt, so there is no need to thoroughly clean the surface before treatment. However, heavy greases and cosmoline should be removed prior to de-rusting as surface contaminants can slow down the process and shorten the life of Evapo-Rust. Additionally, Evapo-Rust is not recommended for use on magnesium or magnesium alloys.
Once the treatment is complete, drain the tank and collect the Evapo-Rust solution, as it can be reused. Check the tank for any remaining rust and repeat the process if necessary. After ensuring the tank is rust-free, rinse it out with a product that will evaporate, such as methylated spirits, acetone, or petrol. Finally, fill the tank with petrol or diesel to prevent future rusting.

Some users choose to store the tank with some diesel inside to create a protective barrier.
Evapo-Rust is safe to use on plastics, but some users have expressed concerns about its safety on O-rings. It is important to plug up the petcock hole and any other inlets or outlets to prevent leaks. Some users have used duct tape, seran wrap, duck tape, and safety wire to seal the tank.

Evapo-Rust is an effective solution for removing rust from fuel tanks. It is safe to use on mild steel surfaces and will not affect PVC, plastic, Viton, rubber, glass, or non-oxide-based paints. To use Evapo-Rust, fill a container with enough solution to cover the item. While Evapo-Rust does contain detergents to penetrate oil and dirt, giving your parts a quick clean with a brush and degreaser will help speed up the process.
Place the item in the solution and soak for 2-3 hours, repeatedly turning it to treat all sides. It is recommended to fully immerse the item to avoid visible lines that may be hard or impossible to remove. If full immersion is not possible, you can use a 12-volt shower to pump the solution from the bottom and wash over the affected areas. This method may be slower but allows you to conserve the product.
After soaking, drain the tank and collect the Evapo-Rust solution, as it can be reused. Check the tank for any remaining rust and repeat the process if necessary. Once satisfied, rinse the tank with a product that will evaporate, such as methylated spirits, acetone, or petrol. Finally, fill the tank with petrol or diesel to prevent future rust.
It is important to note that Evapo-Rust is costly, and you may need a large quantity for full immersion. Additionally, ensure that you plug the fuel tank securely to prevent leaks during the process.

Evapo-Rust is preferred over coatings or liners, which can fail and are difficult to remove
Evapo-Rust is a biodegradable, water-soluble, and safe rust removal product that can be used to treat rust in fuel tanks. It is preferred over coatings or liners for several reasons. Firstly, coatings or liners can fail, especially if the tank is not thoroughly cleaned and rust-free before application. In such cases, the coating or liner can become a potential source of future problems, as it may start to flake or peel, leading to blockages in the fuel system. Removing these coatings or liners can be extremely difficult and time-consuming, often requiring the use of harsh chemicals or even physical cutting and burning, as seen in the experience shared by a user who had to cut open their fuel tank and set it on fire to remove the remnants of a failed liner.
Evapo-Rust, on the other hand, is a straightforward and relatively mess-free process. It does not require the same level of intensive preparation as coatings or liners, and it effectively removes rust from all crevices, leaving a clean surface ready for protection. The product is safe to use on various materials, including mild steel, PVC, plastic, Viton, rubber, glass, and non-oxide-based paints. It is also non-toxic, non-corrosive, and non-flammable, making it a safer option for users and the environment.
Additionally, Evapo-Rust is a cost-effective solution compared to coatings or liners, which often require professional application and can be challenging to repair or replace if they fail. With Evapo-Rust, users can easily adjust the treatment duration and quantity used based on the severity of the rust, and the product can even be reused for treating tools or other smaller items. While Evapo-Rust may be considered pricey, its effectiveness and ease of use make it a preferred choice over coatings or liners, which can be more labour-intensive and challenging to remove if they fail.
Furthermore, coatings or liners can sometimes be unnecessary, especially if the fuel tank is regularly maintained and kept at least halfway full. As gasoline does not promote rust, some users have found that keeping their tanks filled has prevented rust and made coatings redundant. In conclusion, Evapo-Rust is a preferred option due to its effectiveness, safety, ease of use, and reusability, while coatings or liners carry a higher risk of failure and can be challenging and costly to remove or replace.
