So I had our fireplace insert installed last winter and have thoroughly enjoyed the extra heat and not having to contribute as much to the oil budget bill each month. I burned from February through April here last year and the October and November this winter and finally got a sooteater to clean the liner myself. That tool is thoroughly amazing and will pay for itself! Input from people more experienced cleaning, does the cleaning job look to be done sufficiently. 25' insulated liner, didn't make a mess in the house and took maybe 35 minutes. Any tips or pointers from more experienced users would be appreciated! Thanks!
