HMK R175 Exterior Stone Cleaner: Rust Removal for Natural Stone

Overview of HMK R175 Exterior Stone Cleaner

HMK R175 Exterior Stone Cleaner is your go-to solution for tackling rust and rust discoloration on acid-resistant natural stone surfaces. Designed for hard stones and artificial stones, this cleaner also works on glass and certain plastics. Beyond rust, it removes lime scale, construction dirt, mortar residues, and cement haze, making it versatile for indoor and outdoor use. Always test on a small, inconspicuous area before full application to ensure surface compatibility and safety.

How to Use HMK R175 Exterior Stone Cleaner

The cleaner's effectiveness varies with contamination type and level. Cool the surface to its natural temperature before application. Depending on contamination, dilute the cleaner with water in a ratio of 1:2 to 1:15. For heavy contamination, use a 1:1 ratio. Apply to pre-wetted joints and surfaces, allow a short dwell time, and scrub intermittently. Prevent drying by rinsing thoroughly with water. To neutralize, use HMK R155 Basic Cleaner diluted at 1:20 if needed. Avoid contact with sensitive materials like stainless steel and wood.

Key Features and Benefits

HMK R175 is specially formulated to remove rust without damaging acid-resistant natural stone. It effectively cleans lime scale, construction debris, and cement haze, suitable for both indoor and outdoor cleaning tasks. Easy to dilute and apply, it offers effective results across a range of materials including stone, glass, and some plastics.

Application Instructions

Ensure the surface is at a natural temperature before use. Dilute according to contamination level and apply to pre-wetted areas. Let the cleaner act for a few minutes without drying, scrub intermittently, and rinse thoroughly. Apply in shaded areas to avoid drying. Use HMK Z702 Defoamer in a water vacuum to minimize foam. Immediately rinse if in contact with sensitive surfaces.

Storage and Safety Advice

Store in a dry, dark place between 12°C and 25°C, out of children's reach. Ensure good ventilation during use and wear protective gloves and safety glasses. In case of eye contact, rinse with water and seek medical advice. Avoid mixing with other cleaning agents to prevent reactions.
