🛡️ Safety & Storage

• Water-based sprays: Best used within 2–4 weeks. Make small batches for freshness.
  
• Always label your bottles: Include the product name and date made.
  
• Storage: Keep in a cool, dark place away from direct sunlight.
  
• Shake before every use: Essential oils naturally separate from water.
  
• Patch-test surfaces: Especially stone, marble, or specialty finishes.
  
• Safety: Keep out of reach of children and pets. Essential oils are for external use only — never ingest or use undiluted on skin.
  
• Signs of expiry: If the spray changes colour, texture, or smell, discard and make a fresh batch.

🚫 Surfaces to Avoid

Castile Gel (mild, alkaline soap):

• Safe on most surfaces, but avoid:
  
  • Unsealed wood (can leave watermarks or swelling)
  • Marble, granite, natural stone (the alkaline soap can dull or etch)
    
    

Essential Oils (Australian Bush Blend, Lemon, Tea Tree):

• Potent, solvent-like properties can damage:
  
  • Plastic/acrylic surfaces (risk of clouding or weakening plastic)
  • Painted or varnished wood (can strip finishes)
  • Stone surfaces (especially citrus oils like Lemon — can etch and dull stone)
    

Bicarb Soda (mild abrasive):

• Avoid using as a scrub on:
  
  • Glossy plastics (may scratch)
  • Delicate coatings (e.g. non-stick cookware, polished stone)
  • Acrylic bathroom surfaces (can dull shine over time)
    

Citric Acid (acidic, descaling):

• Avoid on:
  
  • Marble, granite, limestone, travertine (all acid-sensitive stones will etch)
  • Aluminium or cast iron (acid corrodes these metals)
  • Natural wood (acid can stain and damage fibres)
    

Washing Soda (highly alkaline, strong cleaner):

• Avoid on:
  
  • Aluminium (causes dark discolouration/pitting)
  • Waxed or polished wood (strips finish)
  • Delicate painted surfaces (alkaline solution may strip paint)
  • Natural stone (etching and dulling)
