I know there are tank sludge cleaners available at HD and Lowes. But do any members have some good advice on this topic? The reason I ask is that I just replaced my oil feed line from the tank to the boiler. The old one was kinked in more than a few spots and full of sediment. There is a filter at the tank. I'm thinking about adding a Gar-ber spin-on mount and filter at the boiler. Moderator: move this to the Lounge if it is more appropriate there.
