Lost in translation...

So is this a thing in the UK? Or is it called something else here? Is UK Methylated Spirits the same - the purple dyed stuff. Is this correct? If not where can you buy denatured alcohol in the UK?

I've seen US jewellers on Instagram using a solution of Denatured Alcohol to help reduce firestain. Which leads me to my next lost in translation thing - Boric Acid. Is that the same as Borax or are they different compounds?

I use Borax for cleaning and laundry so have an abundance and I've just checked our camping supplies as we use Meths for our camping stove, so have a bottle of that too.
