No, alcohol will not work very well. Get a bottle of Uni-Solve. It's a product made by Smith & Nephew. You maybe able to find it locally at a surgical supply store. Most likely you will need to order some. I last got it from http://hocks.com/Merchant2/merchant.mvc?Session_ID=54d9d2dfa697570c44e7042e66c31f06&Screen=PROD&Store_Code=HOP&Product_Code=2958254&Product_Count=&Category_Code=.
