*by G***S on November 30, 2025*

Our outdoor woodstove needs drained and rust inhibitors added as maintenance and the name brand rust inhibitors has gotten so pricey, want to keep up on maintenance to keep it running smoothly so looked for another option. This is the first year of using so can’t speak for longevity of it m, guess only time will tell but so far so good.
