			Hi, 
as mentioned many times before simple things like pineapple juice and some elbow grease work well too. I just had a pedang blade cleaned in this manner followed by ferric chloride treatment to bring up the pattern. Whilst I realise some prefer to leave blades 'as is', in a heavily laminated blade such as this one the skill of the maker and the beauty of the blade might have never been seen again without a clean up like this. There is a before and after of a section of the blade and then a full view of the results.
