Hey guys! I still have not completed cleaning the helmet.. I have been in Korea for a long while and just got back to Sweden recently. I tryed puting the helmet in water with Oxalic acid and letting it stand for a while then cleaning it with a sponge but it seems really hard to get the rust and dirt of. Is there a guide anywhere, I'm wondering if I am doing something wrong? Maybe to cold water or to little Oxalic acid etc etc..

Cheers
