Just put my liner on order and hope to do the instal in another week or two (flex king pro). Silly question but how do you clean a 5.5" liner? I dont see any 5.5" brushes... will a 6 work or will it be too tight? The soot eater thing had me thinking, but how flexable are they to get around a 90* tee? My stove will pass through a somewhat deep thimble into a 90* tee. I can access the roof easily enough and have always cleaned from above. Sooteater would probably work cleaned from above but seems like a waste and extra fiddling with a drill on the roof.
