Hi all I have an apology to make I omitted one important ingredient From the mixture. I am putting it down to a senior moment, so the rusting mixture is as follows:-
One third hydrogen Peroxide
One third saturated Salt solution
One third White Vinegar
And yes the rust turns blue in boiling water.
Once again sorry for the slip up folks
damascus


The only lessons in my life I truly did learn from where the ones I paid for!
