I have a diy 400gpd ro. Last year I forgot to take out the membranes as I was going to replace them anyway. So, they were in there all year. Now, when I went to put the new membranes in, I discovered a very strong musty odor. So, do I need new housings and tubing or can these be cleaned? If they can be cleaned what should I use...vinegar and water...detergent...bleach? Any suggestions appreciated...Thanks, Rick
