Coarse millinery

Micro fibre
A general use of micro fibre cloths (MF) is
not recommended.
Their cleaning power is too strong.
For specific contaminants (eg, fat
residues, hand cream, cosmetic residues,
food residues) a wetted MF can help in
removing gently the traces. However, we
strongly advise against the application of
dry MF cloths. For damage caused by
MF, we assume no liability.
