Hammerite Rust Remover Gel Blister. Non Drip Rust Remover for Metal, Rust Converter - Non Damaging to Metal Paint, Suitable for Interior and Exterior - 100ml, Packaging May Vary

This works it’s like slime jelly to apply. I left it on for three hours then I scrubbed and it removed all the rust if you have stubborn rust do this a few times.

It does work but you have to apply 4 times and let it sit for 1-2 hours

This Hammerite Rust Remover Gel is excellent. If anyone is familiar with the industrial hand cleaner Swarfega, this gel looks exactly like that. It's a bright green gel that you can apply to horizontal or vertical surfaces with a detailing brush. You will need a 25mm (1 inch for our prehistoric American cousins) flat or round detailing brush. Anything larger will not fit through the bottle neck. You cover the rust with the gel. The bright green colour helps you identify where you have brushed it (unless your car is bright green of course). You then wait 20 minutes and see if the rust will brush or wipe off. I found that lighter rust stains would lift off after 20 minutes. The darker rust areas took 2 or three re-applications. You don't need to clean between re-applications. You just brush more of the gel onto those areas. I had purchased a pre-owned car. The car slowly started suffering from condensation. I traced the problem to a missing rubber drain plug in the bottom of the spare wheel well. By the time I discovered the problem, the bottom of the well had brown rust stains. Hammerite Rust Remover Gel sorted the problem beautifully, and most importantly, it did not damage the paint in the wheel well. It's not the fastest rust/rust stain remover. But it works. It's very controllable, and you don't waste any, because its applied by brush and not spray. I was removing rust stains from a painted surface. But if you are removing rust from bare metal, just remember that you will need to apply a rust inhibitor/WD-40/paint, straight after Hammerite Rust Remover Gel does its thing. As it is a remover, not a rust preventer.

Easy to use,but only average performance..

Good stuff nice size tube.Now I have used it I have to say that it really does work! Needs to be reapplied a few times because the rust was pretty bad but it shifted it slowly but it shifted it! For future projects I would recommend gloves or your fingers will end up green and that takes time to get rid of and really hot water 😱🤬 then a good spray of oil and job done 🤪 would definitely get it again nice to have in my tool kit

Removed the rust but was harder work than though despite putting lots of the rust remover on the radiator.

Brilliant

It seemed to work after the first application, but left the metal dark and stained, I tried a couple more applications but it got no better. After a couple of days rust was returning (see second photo). I bought some Barkeepers Friend for around £2.50 elsewhere and had a much better result - see subsequent photos. One of the pairs of secateurs was left pitted, I’m not sure if that was from the original rust or the Hammerite Rust Remover.

Wirkungseffekt gleich null, sehr enttäuschend

Works well.

muy lento en su acción. poco eficaz. Vale mas usar medios físicos que esperar a la efectividad de este liquido

L'ho usato su una brutta colata di ruggine nella vasca da bagno (ghisa smaltata). L'ho dovuto applicare più volte per poter ottenere un risultato definitivo, ma è molto delicato sullo smalto pertanto non lo ritengo un fattore negativo. Dopotutto quel che conta è il risultato finale.

It performed its task efficiently and did not cause any damage to the clear coat of my vehicle.
