Hermosa Water Spot Remover

Use this guide with the product label and safety information. If the label differs from this page, the label takes precedence.

What you’re working towards

Mineral deposits reduced or removed from a compatible, cool surface without letting the treatment dry.

What you need

• Hermosa Water Spot Remover
• Microfibre applicator and clean towels
• Protective gloves and eye protection
• Clean water for neutralising and rinsing

How to treat the marks

1. Wash and inspect. Remove loose contamination and identify whether the marks are deposits or permanent etching.
2. Test first. Treat a small inconspicuous area and confirm compatibility.
3. Apply to a small section. Work at approximately 50 × 50 cm on a cool surface out of direct sun.
4. Allow up to 30 seconds. Agitate stubborn deposits lightly; never allow the product to dry.
5. Neutralise and inspect. Wipe with a clean damp towel, rinse as required, then inspect before repeating.

When to pause

Stop if the surface changes appearance, feels unusually grabby, becomes warm or the product begins drying. Deposits that remain after controlled repeat treatment may be etched into the finish and require correction rather than more chemical dwell time.

Aftercare

Where treatment or agitation compromises an existing coating, re-protect the complete panel for a consistent finish.

Check the surface before you start

Identify the material and the problem you want to treat. Previous coatings, repairs, damage, temperature and application technique can all affect the result. Test a hidden area if you are unsure how the surface will respond.

These directions bring together Hermosa’s product and application guidance and available safety information. They do not mean every material or technique has been laboratory tested. Follow the current product label, SDS and vehicle or material manufacturer’s instructions if they differ from this guide.

Work on a cool surface, out of direct sun, in sections small enough to control. If a first pass does not give the result you expected, check the surface and your method before adding more product, increasing the concentration, rubbing harder or leaving it on longer.

Before you put the tools away

• Inspect the whole treated area in good light, from more than one angle. Check for an even finish and remove residue, overspray and excess product.
• Check visibility and grip wherever the treated surface could affect driving. Resolve any issue before using the car.
• Keep tools for wheels, paint, glass and interiors separate. Clean them after use and discard contaminated consumables.
• Follow the drying, curing and washing restrictions on the label and in the steps above.
• For an unusual material, note what you used and how it responded. It will help next time.
