I’m wondering if the combo of Grease Doctor and a couple of coats of the Rust Doctor would be appropriate for my heating oil tank which is getting quite rusty on the lower half (the tank is located inside my basement). The tank will be hard to access on the back (wall) side. Might I be able to apply the product with a mini-roller (and long handle)?
Rust Doctor and Grease Doctor will work well for you in stopping the rust and protecting the tank from future rust. You will need to clean the tank with Grease Doctor and rinse with water. Remove and loose rust or paint on the surface the best you can. A good way to do this is to apply Grease Doctor to the surface then brush the surface with a wire brush or a Scotch Brite Pad (sold in paint stores). Rinse the surface with water. Grease, dirt, oil, loose paint and rust will all be washed off with the rinse water. If you don’t have a drain in the basement for the rinse water, use a bucket and towels to rinse the tank. You can apply Rust Doctor to the rusty metal by any method that will work for you, including putting it in a garden sprayer to reach into difficult areas. If some Rust Doctor runs onto the floor, just wipe it up with a wet rag. Because Rust Doctor and Grease Doctor are water based, you will not be dealing with strong fumes or toxic chemicals. If you have more questions or need technical help about rust removal, please contact us.
