Thanks

Result is hopefully good but the recipe not so impressive:

I use a brown world famous sparkling-bubbled brown soft drink ,

with phosphoric acid...
for remove rust it's perfect and it's not too strong for the koftgari !

2,5 -3 hours in a bucket, not all the piece ,
just the front side ( I put the liquid gradually ... )

then a sponge and 1000 sandpatch with a little baking soda

that's it
