Cons

  • Needs to be used carefully according to instructions, as letting the gel dry on the surface turns it into a vaselinike consistency that reduces effectiveness.
  • May require multiple applications for stubborn rust or to maintain clean surfaces over time.
  • Some users find the price a bit on the higher side compared to simpler rust removers.
  • Does not dry on the surface, so it must be rinsed off after use, which adds a step in the process.
