Hey everybody! I posted this over in the watch repair forum but didn't get a reply. The threads I have found on this so far has been in this forum so I'm trying here as well. "At the risk of bringing up a very sensitive subject I'd like to discuss waterless cleaning solutions, and more so the home made variety. I've previously used water based cleaners with acceptable results. Some parts have required pegging of jewels and hand cleaning of tough residues from the winding works. I've decided to give waterless cleaners a shot, in part to see if I can get better results and in part because I'm starting to work on more and more valuable pieces, sentimentally and monetary-wise. Haven't had any problems with rust so far but you know, belt and suspenders. I've ordered a gallon of L&R- non ammoniated solution from Beco Technic in Germany (because that's what they had in stock). Turns out though, that because it is considered dangerous goods the shipping cost of that and a gallon of Extra Fine Rinsing solution is more than twice the cost of the two gallons combined. 100 dollars in shipping from Germany to Sweden. Local materials suppliers only supply Elma and Bergeon solutions, with the Bergeon clocking in at 160 dollars plus tax for a 5L jar. And CousinsUK won't even offer shipment of "dangerous goods" abroad. So I'm in a bit of a pickle. The price becomes prohibitive. I've ordered this batch but while I'm working that down I'd like to explore making something safe to use. So here goes: The safety specs for the L&R solution states that it's based on white spirit, e.g. naptha. I assume that some type of detergent would be added to it. I've seen simple green being mentioned before in these discussions. Would a detergent or soap such as that work or behave as it should in a solutions that contains no water? As some of the L&R solutions are also ammoniated, ammonia would also be a good additive. Again, I realize that this discussion is unorthodox. My recent realization about how unavaible decent cleaning solutions are in Sweden, at a reasonable price at least, has made me consider this once again. Best regards Karl"
