Expandwhat is step 2.? Polish with cottom/ and alcohol/ wash in hot water/ use dishsoap/ do nothing
chef's choice!
ExpandDoes it depend if it was chocolate bar or praline
no
Expandif I used coloured CB or not?
no, not if it came out cleanly
ExpandWhat if demolding was not that easy or successfull?
If chocolate or color has stuck to the mold, it may be easier at some point to just wash it.
ExpandI thought residual fat will make demolding more difficult and inhibit shine.
You don't want residual fat, you want a clean mold. Polishing with cotton will remove any fat, but if your chocolate came out cleanly there should not be much or any residual fat to begin with.
