a Raritan Elegance Marine Head about a year ago due to your recommendation. While it's a great head in general, it failed due to salt build up in the exit hose valve. I took it apart, cleaned it and now it is working again. The problem I have is that while out cruising in Mexico I cannot find the Raritan Cleaner that is suppose to be used according to the manual. I brought 2 bottles with me but used them up rather quickly. What other cleaner can I use that could be found locally? I don't want to cause problems using the wrong stuff so if you could give me some options that would help. Thanks, Steve
