Application of FERTAN Rust Remover

One of the most trusted product by industries and classic car enthusiast for rust treatments for over 38 years. FERTAN products have been bestselling rust removers, coatings and primers in Germany and several other European countries for several years now.

FERTAN is very efficient at stopping and removing rust. Loose rust is washed off as dust and the remainder is converted to form a stable and inert surface suitable for coating/painting. FERTAN is a tannic acid, water based product. FERTAN combines superb performance with excellent credentials. In case of skin contact, clean with running water.

Removes Rust without Sandblasting

FERTAN is the optimal treatment for the removal of rust from all metal constructions including:

• vehicles and trailers

• ships, yachts, boats and marine equipment

• metal structures, gates, fences, gratings and railings

• tanks and voids

• constructional steel


FERTAN converts rust to an inert stable material that can be painted or coated. On bare metal, it prevents rust. It is extremely efficient and has unlimited shelf life.

1. Loosen surface rust using a brush, abrasives or pressure washer.

2. Apply FERTAN using a brush, roller or sponge and let it sit for about an hour.

3. Dampen the treated surface with water to maximise penetration.

4. Leave FERTAN to react with the surface for 24 hours at 68°F to 48 hours if lower for best results.

5. Remove the black powdery dust with a damp cloth and leave it to dry.

6. Paint the treated surface with paint within 6 months, for effective long-term results.

1.1 quart of FERTAN treats about 161 sq. ft. FERTAN may leave stains on pale coloured surfaces. We advise removing the stains with a damp cloth.

Safety: In case of contact with skin rinse the affected area under running water. In case of eye contact rinse well and seek medical attention. Not for human consumption.

  1. I’m using the rust converter to maintain farm equipment – works as advertised!
    I really like the fact that it not only seals the rust unlike many other products, it removes the rust and leaves a zinc protective coating.

  2. I just wanted to say what an amazing product this is. I recently used the Fertan rust converter on my metal fence. It was easy to apply and worked even better than advertised. I understand many people use it for car restoration and lawn equipment also.

  3. Works great definitely getting more!! As advertised it converts rust within 24 hours. Easily paint right over! Going to be using this stuff a lot!

  4. Good product. I found it to work better when diluted with 50% water.
