At Renue Systems of Hawaii, we use a specialized system that eliminates mineral deposits completely. The process restores shower glass to its original clarity — spotless, streak-free, and guest ready. It’s not a touch-up, it’s a full reset, leaving your glass looking like it just came from the showroom. The transformation is instant, dramatic, and impossible to miss.
Inspect — We assess the severity of buildup. Every shower is unique, so we match the solution to the surface. That ensures precision results without unnecessary steps.
Treat — Our eco-friendly compounds and specialized system dissolve mineral deposits. It’s powerful where it matters, yet calibrated to protect delicate glass. The buildup lifts off while the surface underneath stays untouched.
Restore — We polish the glass to a like-new finish. The haze disappears, replaced by sharp, crystal-clear transparency. It’s the kind of result that makes bathrooms feel brand new again.
Confirm — You review the results and see the clarity immediately. We don’t leave until you’re completely satisfied. The difference is obvious the moment you step back and look at your glass.
Every shower is different — the number of panels, level of buildup, and location all matter. That’s why we provide custom quotes based on photos you send us. It’s quick, simple, and gives you a clear number without guesswork. You’ll know exactly what to expect before we arrive.
At Renue Systems of Hawaii, we deliver complete hard water spot removal, using the same professional standards trusted by leading hotels and condos across Oahu, Maui, and the Big Island. These are the same results luxury hotels demand — now available for your property. That means the finish isn’t just clean, it’s held to a higher standard.
Our hard water spot removal service is built for hotels, resorts, and condo buildings across Oahu, Maui, and the Big Island. We focus on properties with multiple affected rooms or exterior glass where sprinklers, pool water, or ocean spray have left mineral spots that regular cleaning cannot remove and are starting to hurt the guest experience. We also service select residential shower glass projects on Oahu.
We primarily restore glass surfaces such as shower doors, balcony and pool railings, and exterior windows with sprinkler overspray. In some cases we can also address hard water buildup on glazed tile and certain polished stone or metal trims. During the walkthrough we confirm which surfaces are good candidates and where replacement is a better option.
Most properties schedule hard water spot removal on a one to three year cycle, depending on exposure, sprinkler patterns, and proximity to the ocean. High exposure areas like oceanfront railings or glass near irrigation may benefit from annual service, while more protected areas can go longer once a clean baseline is restored.
Many mineral deposits can be removed or reduced to where the glass looks clear again. If the minerals have etched into the surface over time, complete removal may not be possible, but we can usually improve clarity and appearance significantly. We often start with a test area so you see the expected result before we proceed.
Hard water buildup bonds to the surface and eventually starts to etch it, which is why household cleaners and vinegar stop working. We use professional compounds, pads, and equipment designed to break down mineral layers while protecting the glass. The goal is restoration, not just temporary cleaning, so your staff can maintain it more easily afterwards.
Our system is designed for architectural glass and other finished surfaces. We select the right pads and chemistry, keep the surface lubricated, and control pressure. Work starts with a small test section so we can confirm results and ensure we are improving clarity without introducing scratching or haze.
Yes. After restoration we can apply a protective treatment that helps water sheet off the surface and reduces how quickly new spots form. Combined with simple maintenance steps from your housekeeping or engineering teams, this extends the life of the glass and helps delay costly replacement.
Yes, we offer hard water spot removal for residential shower glass on Oahu in selected cases. The same professional process we use for hotels and condos is applied on a smaller scale, helping restore clarity to heavily spotted doors and panels. We confirm fit, pricing, and scheduling in a quick call before booking.
