Homeowners unable to remove rusted faucet mounting nuts during DIY plumbing repairs

DIYers attempting bathroom sink faucet replacement get stuck when corroded nuts seize onto faucet shanks, preventing disassembly. Current solutions (penetrating oils, pliers, heat) are time-consuming, unreliable, and often result in stripped nuts or damaged fixtures. Homeowners either abandon the project or pay expensive plumber callout fees ($150-300) for a 30-minute job.
