One substance that is not flammable and can help remove creosote buildup from the outside of a stove pipe is vinegar. White distilled vinegar, in particular, is an effective natural cleaner that can help break down creosote and other residues.
Here's how you can use vinegar to clean the outside of a stove pipe:
Mix a solution of equal parts white vinegar and water in a spray bottle or a container.
Ensure that the stove pipe is cool to the touch before starting the cleaning process.
Spray or apply the vinegar solution onto the areas with creosote buildup on the outside of the stove pipe.
Let the vinegar solution sit for a while to penetrate and loosen the creosote.
Use a scrub brush or a soft cloth to gently scrub the creosote off the stove pipe's surface. Be cautious not to apply excessive force, as you don't want to damage the pipe's finish.
Repeat the process if necessary until the creosote is effectively removed.
Wipe the stove pipe with a clean, damp cloth to remove any residue.
Allow the stove pipe to dry completely before using the stove again.
Please note that while vinegar is a safe and non-flammable cleaning option, it's essential to avoid using any flammable or harsh chemicals on the stove pipe, as they can be hazardous when heated. Always refer to the stove manufacturer's recommendations for cleaning and maintenance, and ensure proper ventilation when using any cleaning solutions near the stove or chimney. If you have significant creosote buildup or concerns about your stove's condition, it's best to consult a professional chimney sweep or stove technician for proper inspection and cleaning.
