How to prepare and use…
  • Clean the piece as you would before soldering and assembling.
  • Mix with 1 litre of methylated spirits and 150g of Boric acid in a glass or polyurethane container, with a lid.
  • Depending on the size of the piece cover it entirely by dipping or brushing on a fine coating.
  • Heat all over with a torch to form white-coloured skin, this creates a protective barrier against fire stains.
  • Solder joins normally and cleans the work as normal with acid fire stain will be noticeably reduced.
Supplied: 1kg Tub
