Cleaners
Stain Proof cleaners from Engineering Supplies cover everyday surface care and more demanding cleaning tasks. Choose from Daily Floor Cleaner, Daily Countertop Cleaner, Alkaline Cleaner and Acidic Cleaner according to the material, finish and type of dirt or deposit.
Stain Proof cleaners for daily care
Daily Floor Cleaner, previously Rejuvenata Active, is an enzyme-based concentrate for floors and other suitable hard surfaces. Daily Countertop Cleaner, previously Rejuvenata Spray, provides a separate option for routine benchtop cleaning.
Cleaning stains and mineral deposits
Alkaline Cleaner, previously Oxy-Klenza, is intended for heavier grime and stains such as grease, food and leaf marks. Our listing includes 1 kg and 10 kg packs.

Acidic Cleaner, previously Eff-Erayza, targets deposits such as efflorescence, limescale and grout haze on non-acid-sensitive surfaces. It is listed in a 946 ml pack. Confirm acid sensitivity before choosing it, as acid can etch susceptible surfaces.
Choose for the surface and cleaning task
First, identify the stone, tile or other surface material. Then check any existing coating or sealer and describe the stain or deposit. Also note whether the area is indoors or outdoors.
Follow the selected product’s instructions for dilution, contact time, rinsing and any neutralising step. Test a small area before full application. For planned sealing after cleaning, explore our Stain Proof sealers and check their preparation requirements.
