Sanitary & Descaling
Wollerau.

Wollerau water is medium-hard (hardness level 2–3). For wellness areas, designer fittings, and natural stone, what matters is not the hardness, but the method — material-neutral, without acid.

Hardness 2–3 — but premium bathrooms

Substance.
Material-neutral.

The Höfe region has medium-hard water: hardness level 2–3 from the surrounding springs. The lime load is moderate. For Wollerau estates with wellness areas, natural-stone bathrooms, and coated special surfaces, what matters is not the hardness, but the method.

Designer fittings from Dornbracht, Vola, Axor, Gessi, or Boffi often have special surfaces — PVD, brushed bronze, matt black, rose gold. The wrong acid application here costs not just a cleaning, but the fitting. We work material-neutral. Always.

Wellness with marble, travertine, onyx, or slate calls for absolute acid-freeness. Hygiene yes — but never at the cost of the sealing, stone structure, or coating. Care for the substance, not its shortening.

“Acid is fast. We are careful.”— Muharem Berisha
What acid does to the estate

Risks without
a material-neutral method.

Acid-based descalers dissolve lime — and at the same time substance that does not come back. Four damage patterns we regularly see at Wollerau premium bathrooms.

014 Risk

Chrome & PVD damage

Designer fittings
  • Acid damage on PVD surfaces (matt black, rose gold)
  • Designer fittings (Dornbracht, Vola, Axor) irreparable
  • Brushed bronze dull and stained
  • Original chrome corroded
024 Risk

Glass etching

Walk-in · Nano-coated
  • Acid etches glass showers permanently
  • Nano coating washed out
  • Anti-lime protection destroyed
  • Mirrors with irreversible streaks
034 Risk

Joints & silicone

Wellness · Sauna
  • Acid dissolves silicone seals over time
  • High-quality wellness joints become porous
  • Mould risk increased
  • Restoration costs exceed cleaning
044 Risk

Natural stone

Marble · Travertine · Onyx
  • Marble reacts immediately to acid — etching marks permanent
  • Travertine and onyx particularly sensitive
  • Slate in wellness dull and stained
  • Estate premium floors damaged
How we work

Material first.
Agent after.

Three steps — from material check to sealing. On designer fittings, natural stone, and wellness coatings, the material assessment is the most important step.

013 Risk

Material check

Fittings · Stone · Glass · Silicone
  • Designer fitting material identified (PVD, bronze, rose gold)
  • Natural stone and wellness coatings mapped
  • Coatings checked for reaction compatibility
024 Risk

Material-neutral descaling

Without acid
  • Enzymatic and citrate-based agents without metal damage
  • Designer fittings treated material-appropriate
  • Natural stone cleaned without etching
  • Wellness coatings unchanged
034 Risk

Sealing

Protection for the interval
  • Optional lime-protection sealing after descaling
  • Significantly extends the cleaning interval
  • Permanently protects designer fittings
  • Recommended for wellness and glass showers
Three areas

Lime dissolved.
Substance preserved.

013 Risk

Wellness areas

Sauna · Steam bath · Pool

Premium wellness with natural stone, glass surfaces, sauna wood, and pool surrounds — cleaned material-neutral, coating intact, hygiene preserved.

  • Natural stone acid-free
  • Glass streak-free, nano layer intact
  • Wellness wood cared for
023 Risk

Designer bathrooms

Dornbracht · Vola · Axor

Designer fittings with special surfaces — PVD, brushed bronze, matt black, rose gold — material-neutral descaling, without acid, without damage to the substance.

  • PVD coating unchanged
  • Marble & travertine acid-free
  • Glass showers streak-free
033 Risk

Guest bathrooms & WC

Sanitary ceramics · Coated

Guest bathrooms and WCs with premium sanitary ceramics and coated special surfaces — regularly cared for, material-neutral, without damage to the sealing.

  • Premium ceramics (Duravit, Laufen, Villeroy) deep descaled
  • Coated WC inner surfaces protected
  • Material-neutral, without aggressive acid

Frequently asked questions

Descaling Wollerau —
in confidence.

What is the water hardness in Wollerau and what are the consequences?+
The Höfe region has medium-hard water (hardness level 2–3). The lime load is moderate — but on designer fittings, coated special surfaces, and natural stone even a low load calls for the right method. We work material-neutral.
Are you experienced with designer fittings (Dornbracht, Vola, Axor)?+
Yes. Dornbracht, Vola, Axor, Gessi, Boffi — high-quality fittings often have special surfaces (PVD, brushed bronze, matt black, rose gold). We use exclusively material-neutral agents. No acid. No dull patches. No coating damage.
How do you care for wellness areas with natural stone?+
Wellness with marble, travertine, onyx, or slate calls for absolute acid-freeness. We clean with pH-neutral agents, checked on the specific substance. Hygiene yes — but never at the cost of the sealing or the stone structure.
What if previous owners used acid?+
We inspect the substance before the assignment starts. Dull patches, lime stains, damaged coatings are documented. What we can repair, we do; what needs a restoration company, we recommend transparently — no pseudo-solutions.
How discreet is sanitary care at the estate?+
Fixed team, quiet way of working, no branding on the property. Appointments in your absence are possible — with key management, documented handover, and written confirmation. For particular confidentiality needs, NDA available.
What rhythm do you recommend for descaling?+
With medium-hard water usually half-yearly for wellness and heavy use, yearly for guest bathrooms. With high frequency or several water-use points more closely spaced. We agree the rhythm with you personally based on your use.
