Me and heights do NOT agree - I'm scared like a little schoolgirl if I stand on a chair to change a light bulb so going on the roof is a "never gonna happen" situation for me (it's a very steep pitched roof). How then would I clean the chimney in my Opel 3 ZC fireplace? I'vs never cleaned a chimney myself so am unsure of the process itself. What do I need to do the job? There's about 16' of chimney to the top and then the cap. If I clean bottom up, how do I avoid damaging the cap? Even more important, how do I avoid making a huge mess inside the house?
