MB-2 Alkaline HD Alkaline Cleaning Solution
Heavy-Duty Stone, Tile & Grout Cleaner – Professional-Strength, Biodegradable Formula
Key Features
Super-concentrated formula in a bottle. A clear, high-pH (≈ 12.5) liquid packs deep-cleaning alkalinity that dislodges mineral build-up, ground-in soil and cementitious haze from natural stone, ceramic or porcelain tile, and grout.
Stone-safe chemistry. Unlike acid-based strippers that can etch marble or limestone, MB-2’s alkaline formulation attacks dirt – not calcium carbonate – preserving polish and color integrity.
Biodegradable by design. Formulated with modern, readily biodegradable surfactants to cut environmental load on jobsite discharge.
Concentrate = control. Dial dilution from light film-lift (3 oz/gal) to heavy restoration (8 oz/gal) so you never over-spend or under-perform.

Compatible Surfaces (and Why It Matters)
Natural Stone Floors & Counters
Alkaline pH breaks organic soil without dissolving calcium-based stone, so polished marble, travertine, and limestone emerge streak-free and ready for sealing.
Ceramic & Porcelain Tile
Glazed or unglazed—MB-2 loosens traffic grime that mop detergent can’t touch, restoring original slip coefficient before you apply a maintenance cleaner.
Grout Lines
High viscosity surfactants wick into porous cement grout, suspend soil and rinse clean, leaving an even tone that clients notice.
Not a degreaser. For kitchens or industrial grease removal, pair MB-2 with a true degreasing agent such as Easy Oxy after rinsing.
How to Deep-Clean with MB-2 Alkaline HD
Prep & Inspect
Sweep or vacuum away loose grit. If topical wax or acrylic was applied, strip it first; coatings block chemical contact. Test MB-2 on a discreet spot to confirm colorfastness.
Mix Your Dilution
Light soil = 3 oz/gal (25 mL/L)
Medium soil = 6 oz/gal (50 mL/L)
Heavy soil = 8 oz/gal (65 mL/L)
Blend with hot water for maximum surfactant activation.
Apply Generously
Flood the area with a pump-up sprayer or microfiber mop until joints stay wet. For counters, use a saturated sponge. Allow solution to dwell—heavier contamination benefits from a longer contact window (up to 10 min) but never let it dry.
Agitate for Mechanical Lift
Scrub tile faces with a nylon deck brush; work grout joints with a stiff, short-bristle hand brush. On stone floors, a 175-rpm machine with white pad accelerates productivity on large footage.
Extract & Rinse
Wet-vac slurry or mop it away, then rinse twice with clear water. Final-buff with a clean white pad for a uniform finish.
Protect the Clean
Once the surface is bone-dry, lock in the result with MB-24 Barrier impregnating sealer; routine care can then switch to MB-1 (floors) or MB-5 (counters).
FAQs
Is MB-2 safe for food-prep counters?
Yes—after rinsing thoroughly per Step 5, follow with a neutral daily cleaner before returning the surface to service.
Can I use it every day on honed marble?
MB-2 is restoration-grade, not a daily wipe. Use only when soil loads exceed the capacity of neutral cleaners.
Does it remove grease?
Yes, MB-2 acts as a degreaser as well..
Personal protective equipment?
Gloves are recommended; ventilation mask only if you are odor-sensitive. Always read the SDS for full safety guidance.
Why Choose MB-2 Alkaline HD
Biodegradability where others rely on butyl solvents. Many degreasers tout cutting power but carry VOC penalties; MB-2 avoids butyl glycol, making disposal simpler.
Stone-shop heritage. Developed by MB Stone Professional®, the same lab that created MB-3 Soap & Mineral and MB-24 Barrier, so chemistry aligns across your workflow.
Works Best With
- MB-24 Barrier – seal natural stone immediately after deep clean to inhibit re-staining.
- MB-1 Floor Amore – a pH-neutral follow-up for daily maintenance.
- MB-5 Stone & More – streak-free everyday spray for counters and vertical stone.
Preparation:
- Mix MB-2 Alkaline HD in the following proportions with hot water:
- Light soiling: 3 ounces to 1 gallon of water
- Medium soiling: 6 ounces to 1 gallon of water
- Heavy soiling: 8 ounces to 1 gallon of water
- Stronger solutions can be used for extremely soiled conditions
- For routine cleaning, use MB-1 Floor Amore for floors or MB-5 Stone & More for other hard surfaces.
- Always test product in an inconspicuous area.
Directions:
- Remove all loose debris from the surface to be cleaned.
- Strip the floor from wax or any topical sealers.
- Apply the diluted solution liberally with a mop or a sprayer and allow the product to dwell. For small areas, use a cotton rag or sponge.
- The level of soiling will determine dwell time. Light soiling may require a very limited dwelling time, a few minutes. The longer the product is allowed to dwell, the easier the cleaning procedure will be.
- Do not let the product dry on the surface being cleaned. Agitate the solution with a hand brush or mop.
- Remove the solution with a mop or, for best results, with a wet/dry vacuum cleaner. For small areas, use a dry cotton rag or sponge.
- Rinse thoroughly with plenty of clean water.
- Once the floor is dry, buff to a uniform clean using a white nylon pad.
To help prevent deep soiling and staining in the future, apply MB-24 Barrier.
