Specialized Tool/Solution for Unsealing Stuck Lids or Corroded Threads

Many household items, particularly those involving salts, sugars, or certain minerals, can seize up due to crystallization or corrosion, making lids impossible to open without damage. There's an opportunity for a niche product – either a specialized tool designed to provide leverage and grip for difficult-to-open caps without damaging the item, or a targeted solvent/lubricant specifically formulated to dissolve salt/sugar crystals or break down light corrosion in threads. Such a product could be marketed to hobbyists, thrift store enthusiasts, or anyone who frequently encounters seized containers (e.g., spice jars, antique bottles, canning jars with stubborn lids).
