Cleaning New Ss Fittings

[A3k]

Hi fellas,

i just got a heap of new stainless steel fittings from overseas.

they're a bit filthy, and have what i assume is cutting fluid inside.
anyone know what the best way to clean these are? can i just soak in napisan or do i need to use detergent first?

thanks
Al

Degreaser --- rinse well --- boil throughly --- 100% Sodium perc or Napisan --- sanitise with Phos acid\Starsan or whatever.
