How to wash/clean methamphetamine acetone HELP

Hi. Can anyone who is educated somewhat tell me how I can go about cleansing my ice? I need this because of a harm reduction reason. Yeah I'm getting lit but so what don't hate on me for my addiction. This shit unusually has some weird cut in it I would like to remove.... Simple as that. Does anyone here know about how I could do the acetone wash to remove this bullcrud? Thanks and don't hop on here to judge me. Education and harm reduction is the purpose of my post. Thanks
