Hi guys,

I've finally managed to mould two ( Offside & Nearside ) headlight cover moulds using EC CS25 Silicone rubber.
The quality and definition of the finish is superb!  

While I've been busy working on the next stage of the procedure ..................  casting 'Vac-Cast Epoxy Resin' into the silicone moulds,  a week has elapsed.

Now my silicone moulds have built-up an oily residue inside them!?  >>



My question is .............  can I simply 'wash out' with just a damp cloth the oily residue?
Or should I be cleaning the residue off with EC Mould Cleaner?

Other option I've read about are - Soapy water
Or even,  talcing powder!?

And,  how will this effect my Vac-Cast Epoxy Cast?

Any opinions ( comments ) greatly received.



Many thanks

It is definitely a mixing issue - have seen it with some of our condensation cure silicones when they are mixed off ratio, the oils from the unreacted components leach out. 

Be a bit careful, on the odd occasion the moulds with this problem will stick. Use your Mann Ease Release before casting into the mould.
