Masonry Cleaner, Wall Wash Cleaner, Wall Mineral Cleaner
RXSOL Mineralite Wash is a fast-acting, inhibited mineral cleaner formulated to remove cement haze, mortar/efflorescence, hard water scale, atmospheric grime, and rust streaks from Mineralite (cementitious) plaster, concrete, brick, and stone. The blend of buffered organic and inorganic acids, plus wetting agents and a corrosion inhibitor, gives rapid soil breakdown with reduced fuming and better substrate safety compared to straight mineral acids.
- Chromate/nitrite free
- Low-fume vs plain HCl
- Designed for professional façade cleaning prior to coating or handover
Key Features of RXSOL Mineralite Masonry Wash
- Works 3–5× faster than non-acidic cleaners on mineral deposits
- Inhibited to reduce attack on sound cementitious matrices and nearby metals
- Buffered to improve control and reduce pungent fumes
- Wetting/dispersing system reduces streaking and re-deposition

Areas of Application of RXSOL Mineralite Masonry Wash
- External Mineralite or cementitious plaster walls
- Concrete, blocks, bricks, pavers, and most natural stones*
- Removal of: cement splashes, laitance, efflorescence, atmospheric dirt, rust stains from rebar bleed or fixtures
*Always perform a small patch test; avoid acid-sensitive stones (e.g., limestone/marble/travertine, polished granites)
Use caution / test first: colored renders, architectural finishes, natural stones
Not recommended: polished limestone/marble; galvanized or bare aluminum/zinc surfaces; glass and anodized finishes (mask beforehand)
Do not use if: Substrate is acid-sensitive (e.g., calcareous stones) or has hairline cracks exposing steel. Fresh plaster is <14 days old (risk of uneven etch/whitening). Temperatures are below 5 °C or above 40 °C; or during rain.
Equipments to use: Low-pressure chemical sprayer (acid-resistant), soft brushes, water supply for flooding rinse, wet-vac or controlled runoff capture if required by site EHS.
A. Surface Preparation
- Pre-wet the façade thoroughly with clean water (saturate pores; avoid dry suction).
- Mask/meticulously protect metals, glass, painted/varnished surfaces, landscaping, and drains.
- Heavy efflorescence/rust/cement bloom: 1 + 1 (1 part product : 1 parts water)
- Normal deposits/soiling: 1 + 3 to 1 + 8
- Light maintenance wash: 1 + 10
- Always add product to water, not water to product. Use plastic containers.
- Apply from bottom-up using low-pressure chemical sprayer or soft acid-resistant brush.
- Allow 2–5 minutes dwell time. Do not let it dry.
- Agitate stubborn areas with a soft brush.
- Rinse copiously from top-down with fresh water until runoff is clear.
- Repeat if necessary (light second pass is common on heavy crusts).
