I have just purchased a new Uhlmann foil lame, and have been using it at a considerable number of tournaments. What is the proper way to wash it (

I seem to have lost the washing instructions somewhere)? On my old lame I used a cold water bath with Dreft Baby Soap (which seemed to work quite well), but I have heard of using an ammonia mix. I would rather not touch the ammonia, but I will take suggestions... thanks
