Why choose this product range
Over 25 years of development experience — research continues today
Korea Total Service continues researching products and application processes, drawing on more than 25 years of development experience. Customer requirements are our starting point: we connect soil sources, materials and actual working conditions when developing product specifications.
Product-specific technical priorities
Rust and metal stains may originate from external hardware or minerals within the stone. Source, color, penetration and stone sensitivity guide a localized treatment approach connected to recurrence-source management.
Materials and process together
We assess surface changes, recovery, rinsing, drying and follow-up care alongside cleaning objectives to propose usable field methods.
Custom development and improvement
Manufacture after order is our basic policy, including general-purpose products. Customer requirements and application feedback inform subsequent specifications.
From customer requirements to product specifications
- Review photos, materials, contamination, operating conditions and objectives
- Select product and process options; discuss samples or spot trials when needed
- Manufacture and supply to agreed specifications, with application guidance
- Review outcomes and maintenance records to discuss improvements
Final ingredients, instructions, SDS and performance documentation are provided for the agreed product specification. These are development and selection criteria, not quantified guarantees of identical outcomes in every condition.
Purpose
Assessment of rust and metal stains near pots and fittings
Materials to assess
Select a stone-specific method after compatibility assessment
Specific conditions
Identify external corrosion versus mineral-origin staining. Deep stains may need specialist restoration; do not apply general acidic rust removers indiscriminately.
Workflow & inspection
- Identify stone, finish, treatments and contamination history.
- Test a discreet area for appearance, gloss and residue.
- Follow finalized labels, SDS and technical data for application and worker protection.
- Reassess after required rinsing and drying before protection or restoration.
Before-and-after checks
Before work
Record location, color and depth of staining, gloss, moisture and existing films.
After work
Compare under the same lighting and dry conditions; inspect residue, color, gloss, slip and recurrence.
Supply specifications
Discuss jerrycan, small-pack or gallon packaging by family. Poultices, powders and resins have separate specifications.
Questions before selection
- What are the stone, finish and exposure conditions?
- Does the mark disappear when wet and return after drying?
- What acids, waxes, repellents or polishing were previously used?
- Is the goal cleaning, natural appearance, enhanced color or restored gloss?
