    If the sintered metal filter is dirty & not available I used air conditioning coil cleaner on my Mercury filter. Pour a shot glass full & soak overnight & if it is real dirty repeat. It will not hurt the filter as it’s made for aluminum coils cleaner. Comes in a quart size at A.C. supply houses. Many thought it wouldn’t work until I sent them some. Mercury filters are in the tank so been in there from new I’d guess & very plugged & dirty.
