SPOT OFF – 1 Gallon (HF Acid-Based Hard Water Spot Remover)

Formulated with a unique liquid pumice blend and HF acid base, it’s ideal for removing mineral deposits and hard water spots caused by sprinklers and rainwater. Not intended for daily use — best for problem areas that require deep cleaning.

Key Features:

  • HF acid-based formula for maximum cleaning power

  • Removes stubborn hard water spots and mineral stains

  • Ideal for use on glass, painted surfaces, and problem areas
