Steel brush or rotary whip for heavy creosote? My choice cost me a Saturday
Been doing this 9 years. Hit a chimney in Portland last month with crusted stage 3 creosote. I always used steel brushes, figured they were the tried and true way. But a buddy swore by rotary whips, said they chew through glaze way faster.
So I tried the rotary on a job. Worked great on the top half. Then it bound up on a tight bend, snapped the cable. Spent 4 hours fishing it out. Client watched the whole thing. Not my best look.
Steel brush took me 2 passes but never got stuck. Rotary was quicker when it worked. Now I'm torn on which to pack for the big jobs.
Anyone else hit this wall? Which side do you land on?
