Another way to tackle the problem of cleaning gold ornamented blades is to paint over the gold with nail polish, but this is not recommended unless the gold does look to be pretty secure. The polish comes off easily enough with acetone.

Yes, I agree with you. I have cleaned once a blade with gold by brushing the blade carefully with fresh opened lemons which I have bought in an asia shop.
