I dont know if you guys know of this little trick, but we use it often to strip rusted parts of all rust without any manual effort :bigsmile:. Great for old cars with parts you want to strip with minimal effort and minimal wear to the part.
The below link is from last year where me and my buddy Jesper renovated the front brake calibers of my 206 GTI after i found some small dmg while changing brake pads

Making this mixture always wear full face protection and gloves!
The Mixture is a mix of Sodium hydroxide and zinkoxide, that attacks rust leaving steel and irons totally free from rust and also most paints.
The mixture will eat any aluminium and most other metals that are not steel or iron, also fingers, eyes, and any organic you put in there, so use protection!!!!!!!!!!!!. Most plastics are unafected, so it is great for rusted tools aswell
To be warned the mixture have to be pretty hefty and heated up to a good 120-130degrees, so again safety first, this stuff will melt your face some fierce!
You need a homogeneous mixture of water and Sodium hydroxide, and here it is very important that if you do not hit the homogeneous mixture, that you do not add neither water or Sodium hydroxide while the bath is hot!!! Adding water to a mixture that is 100+ degrees will make the bath explode in your face!!!!
Same goes for adding Sodium hydroxide!!!! The heat buildup around the Sodium hydroxide if you add it to a boiling bath will make the bath boil violently and explode in your face again!!!!
Now that the explode in your face warnings are out of the way we can go on to the actual bath
You need waaaay more Sodium hydroxide than water n the mixture so no pointis starting off 1 to 1, use like 1 liter of water and add SLOWLY minimum 3-4kgs of Sodium hydroxide. ofc if the bath is not full you need to add more of both.
Don't do this the other way around!!!! Don't add water to pure Sodium hydroxide! Then we are back to the whole explode in your face thing! If the mixture cannot hit 120degrees celcius then you need to add more Sodium hydroxide WHEN IT IS COOLED DOWN! ELSE EXPLODE! FACE!
When it is possible to hit 120-130C add a couple of teaspoons of zinkoxide.
Put down your rusted item turn up the heat and leave it for 2-6hours with the heat on.
Also i dont reccomend doing this in the kitchen.
If the bath ever turns less effective, filter it trough a steelstrainer and add more zinkoxide ^^ and ofc once in a while new water needs to be added when it vapourize.
Enjoy your deadly chemicals :amuse:
