Review: Excellent product - Excellent product in a small quantity, galvanised steelwork prepared for painting
Review: It works! - So I applied to weathered galvanized metal as if it's glav' I don't really have a reason to paint that, although I can understand why someone may wish to. The metal did indeed blacken, I left this overnight and I was pleased with the result as I could see a reaction had taken place. I think for lifting something after weather and age has taken it's toll this is going to be useful to have to hand.

### ⭐⭐⭐⭐⭐ Excellent product
*by A***. on 9 August 2025*

Excellent product in a small quantity, galvanised steelwork prepared for painting

### ⭐⭐⭐⭐ It works!
*by C***S on 26 April 2023*

So I applied to weathered galvanized metal as if it's glav' I don't really have a reason to paint that, although I can understand why someone may wish to. The metal did indeed blacken, I left this overnight and I was pleased with the result as I could see a reaction had taken place.

### ⭐⭐⭐⭐⭐ Clean and clean again.
*by 2***T on 18 July 2023*

This stuff came with a page of instructions which were concise but clear. I thought I had followed them pretty well but it became apparent that the galvanised tube I was applying the solution to was not properly cleaned. When I brushed the solution on it was very obvious that I hadn't done a good enough job preparing the surface. It must be as free from any oil, grease or other contaminants as you can possibly get before you apply it. Get that part right and it works very well. My ONLY issue is that I wish they sold it in smaller quantities because you really don't need much if you do the prep right.
