Hard Water Stain Removal in Walnut Creek and the East Bay

Hard water stains, mineral etching, oxidation, paint, cement and silicone removed from glass as a separate restoration service, quoted after inspection.

Professional Hard Water Stain Removal Services for a Healthier Home

Some marks on glass are not dirt. Sprinkler overspray leaves mineral deposits that bond to the surface and can etch it over time. Construction leaves paint, cement and silicone behind. A regular window cleaning removes normal soil, but it is not designed to remove bonded contamination or damage.

Glass restoration uses specialized chemicals, polishing systems and mineral-removal techniques, and takes more time than cleaning. We inspect the glass first and tell you what can realistically be removed, what can be improved and what is permanent damage.

What is included

  • Inspection to separate bonded contamination from permanent damage
  • Hard water and mineral deposit removal
  • Treatment of light etching and oxidation where possible
  • Paint, cement, silicone and construction residue removal
  • Final rinse with 0 TDS pure water
  • Advice on stopping sprinklers from causing it again

Step by step

How the job runs

  1. Step 1 of 3

    Inspect

    We look at the glass up close and test a small area to see how the deposits respond.

  2. Step 2 of 3

    Restore

    Mineral removers, polishing and careful hand work, matched to what is on the glass.

  3. Step 3 of 3

    Rinse and review

    A pure water rinse, then we review the result with you, window by window.

Why we finish with 0 TDS pure water

  • Tap water carries calcium, magnesium and silica. When it dries on glass, those minerals stay behind as spots.
  • Our filtration system strips the dissolved solids out, down to about 0 TDS (total dissolved solids).
  • With nothing left in the water, the glass dries on its own without mineral spots, and nobody has to wipe it with a towel.
  • Water-fed poles carry the pure water up to about 40 feet, so most second-story glass is cleaned from the ground.

I’m very happy with the carpet and home cleaning service! From start to finish, the team was professional, efficient and very respectful of my home. They did an excellent job cleaning the carpets and made everything look and feel fresh again. I really appreciated how thorough they were and how much attention they paid to the details. They went above and beyond for our home and the results were impeccable. The entire process was smooth and easy. I would definitely recommend Mr. Pedro and his company to anyone looking for reliable, professional, and high-quality carpet and home cleaning services. I’ll definitely be using them again in the future.

I still have questions See all 60 answers

Can all hard water stains be removed?

Fresh deposits usually come off. Glass that has been etched for years may improve without becoming perfect. We test first and tell you.

Why is this priced separately?

It takes specialized products, polishing and much more time per window than cleaning.

How do I stop it from coming back?

Adjust sprinklers so they do not hit the glass, and keep windows on a regular pure water cleaning schedule.
