I'm trying to clean my filter. I can't find any filter cleaner in stock or not on back order in my area so UNI site said dish soap or simple green. I used dish soap yesterday barely did anything to get rid of the old filter oil. Used simple green today and got rid of a little bit more of the old filter oil.
So my question is does it matter if there is some old filter oil left on the filter.....like is that normal no matter what you use?
