PRESERVE
YOUR LUXURY.

Yes. Fighter is formulated to be safe on tempered glass, ceramic tiles, vitrified tiles, stainless steel, chrome, and brass fixtures. Avoid use on natural stone (marble, granite) and painted surfaces. Full surface guide is in the instructions.

Yes — in most cases. Old hard water stains are thicker mineral layers, so you may need 2–3 applications with a light scrub between them. The acid dissolves the same calcium and magnesium deposits regardless of age. Extremely heavy crust from years of neglect may require repeat treatments.

Vinegar (acetic acid) has a pH of around 2.5–3, which is effective for light scale. Indian borewell water with 400–900 TDS deposits a much denser mineral layer. Fighter uses a multi-acid system (methane sulfonic acid, lactic acid, gluconic acid) at pH 3.4 — specifically engineered for high-TDS conditions.

No scrubbing required for regular maintenance. Spray, wait 60 seconds, wipe or rinse. For heavy buildup, a light scrub with the included coconut fiber pad speeds things up — but the acid does the actual dissolving work.

Fighter contains acid — it's not a purely "natural" product, and it shouldn't be. That's exactly why it works where natural alternatives fail. It's diluted to a safe-use concentration, comes with gloves, and has a citrus fragrance. Keep away from children and pets during application. Once rinsed, the surface is completely safe.

Depends on your TDS level and how often you use the shower. In 400–600 TDS areas, glass stays clear 3–4 weeks with monthly maintenance. In 700+ TDS areas, a bi-weekly application works best. Fighter also includes a slow-mineral-return coating in the formula.

Every order includes: 500ml Fighter bottle, 2 coconut fiber scrubbers, 2 microfiber cloths (40×40cm), and 1 pair of nitrile gloves. Everything you need to get started.
