Sika Rustoff-100, Rust remover cum passivator liquid, easy-to-apply, for protecting steels, 1kg

Solove my purpose. Ya .. it takes 48 hours to dry. But superb. Mainly on grill where it not possible to reach all sides and corners. It saves 80% of labor to remove rust by hand or wire brush.

Earlier i have reviewed Rust-x rust converter. now i came to try Sika rust remover.1. Sika is thin watery liquid while Rust-x is whitish creamy thick liquid.2. Applying Sika needs extreme care because it is thin and gets spattered around also i felt fumes out of rust reaction from it. Felt burning like irritation on my skin wherever it’s tiny drops landed while brushing. but rust-x is safe on skin even with brushing vigorously.3. Result of sika is good with steel and very thin layer of rust only. But Rust-x just kills a thick layer of rust and converts it to smoothened water resistive layer satisfactorily.Yet no great point of use of sika for me. but results may vary according surfaces of application.

The product does not work at all. Rust does not get removed.Kindly do not buy this product.

It indeed has Maleic Acid (like similar rust killers), but is not very effective, if the layer of rust is thin. Only if the rust layer is thick, it works. Which is somewhat contrary to the instructions. Only the flaky rust needs to be removed. Hence, it seems, it will work only in the case of heavily rusted articles. Further, you need to was away the residual acid carefully after 48 hours. In all it takes at least 72 hours to finally finish a treatment with this product. You need at least two coats, careful brushing and a final wash with lots of water. So, it is not an easy matter.

It shows that if u apply it the iron will turn black bt it doesn't.... It just turns it to some grey colour... The finish is not so good to....Overall I'll say it's not worth.... It not doing it's job....

Remove loose rust particle using soft iron brush. then apply sika rustoff.

What I was looking for. It clears the rust, easy to apply. Now they say that it prevent the rust to form again, so I am hopping that it will.
