Hi folks!

I has builded the 65 mm dia x 190 mm length boiler with water tube for my model coastal steam boat.

But the flux from silversoldering are inside the boiler. How can i remove the flux out of boiler before use?

Will the flux be removed by hot water?

Keep flushing it out with hot water.

Or your acid pickle will also remove it.

Hi Jens,

leave your boiler pickling overnight in diluted lemon juice, One lemon squeezed and mixed with 1/2 ltr of water or even less should do the trick, It will remove all the flux
