Hi i just spent my time to read the care booklet inside the envelope and i come across this chamois cloth mentioned inside the book....my big question is...is it safe for the new gold hardware? i encountered such experience last time when i cleaned my GHW on lv mutlicolore alma, and the gold turned color to pale-almost silver!! thats why im asking opnion on those who are more experience or has done this before...is it safe to use the cloth to wipe the GHW? thanks a lot guys!!
