Neji-Saurus Screw Removal Liquid Rust Remover ZC-28

Takes off rust on screws well

Only needs a minute to remove rust… I was a little fearful of it causing damage to items, so did not leave on for too long, but would be happy to leave on item longer going forward. Definitely works.

Buen producto, precio inmejorable

J’ai enlevé la rouille sur des vieux outils. J’ai dû en remettre plusieurs fois. Il faut quand même poncer après. Odeur assez forte.

錆びついた鉄に液体を掛けた途端、液体が紫色に変色し、錆がどんどん落ちていく。あっという間に錆が取れました。匂いはちょっとツンとする匂いがあるので、窓を解放させて使ったほうが良い。

It doesn't work like it shows in the pictures and I still had to use a lot of brushing and sanding to remove rust. However it freed seized items (wheel on shaft) and probably loosened a lot of surface rust.It should come with clear instructions so that you know whether it works or not. It smells quite like sulphur but at least it's safe to use and I would use again
