Why You Only Need 6 Ingredients to Clean Your Entire Home
Walk into any grocery store and you’ll find dozens of specialised cleaning products — one for the kitchen, one for the bathroom, one for glass, one for wood, one for carpets. It’s overwhelming, expensive, and almost entirely unnecessary.
Six natural ingredients, most of which you may already have, can handle every cleaning job in your home. This guide profiles each one: what it cleans best, what to avoid, safety considerations, and where to buy it cheapest.
Ingredient 1: White Distilled Vinegar
What it is
A diluted acetic acid solution (typically 5% concentration) made from fermented grain alcohol. Safe, food-grade, and biodegradable.
What it cleans best
- General surface disinfection
- Mineral deposits and limescale (shower heads, kettles, coffee makers)
- Glass and mirrors
- Grease on stovetops and appliances
- Odour elimination (pour undiluted into drains, toilets)
- Fabric softener replacement (add ½ cup to rinse cycle)
Do NOT use on
- Natural stone (granite, marble, travertine) — acid etches the surface
- Cast iron — promotes rust
- Waxed wood floors — strips the wax
Safety
Completely safe. Avoid mixing with bleach (produces chlorine gas). The smell dissipates quickly as it dries.
Where to buy cheapest
Grocery stores in 1-gallon jugs: $3–$5. Buy in bulk at warehouse stores (Costco, Sam’s Club) for $6–$8 per 2 gallons. See bulk vinegar on Amazon.
Ingredient 2: Baking Soda (Sodium Bicarbonate)
What it is
A mild alkali that reacts with acids (like vinegar) to produce CO2 bubbles — useful for fizzing action in drains and on stains.
What it cleans best
- Scrubbing surfaces without scratching
- Deodorising (carpets, fridges, bins, shoes)
- Baking residue on oven surfaces
- Laundry booster (adds to detergent to boost cleaning)
- Drain maintenance (combined with vinegar)
- Removing coffee and tea stains from mugs
What to avoid
Don’t use on aluminium surfaces — it causes discolouration. Avoid combining with vinegar if you want the cleaning properties of both — they neutralise each other when mixed. Use them sequentially instead.
Where to buy cheapest
Baking aisle in 1–5 lb bags: $1–$6. Buy the large baking soda bags from restaurant supply stores or Costco for the best per-pound price.
Ingredient 3: Castile Soap
What it is
A plant-based soap made from vegetable oils (traditionally olive oil, now often hemp, coconut, or jojoba). Concentrated, biodegradable, and free of synthetic detergents.
What it cleans best
- Dishes (diluted)
- All-purpose cleaning surfaces
- Floors (diluted in bucket)
- Hand washing and body wash (it’s skin-safe)
- Laundry (works well in warm/hot water)
- Fruit and vegetable wash (dilute heavily)
What to avoid
Don’t mix directly with vinegar — they react and form a white residue. Use them separately. Don’t use undiluted on delicate surfaces.
Where to buy cheapest
Dr. Bronner’s unscented (32 oz) is the gold standard: $12–$16. Baby/unscented versions are most versatile for cleaning. Check Dr. Bronner’s prices on Amazon.
Ingredient 4: Washing Soda (Sodium Carbonate)
What it is
A stronger alkali than baking soda. Not the same as baking soda — don’t substitute them. Found in the laundry aisle.
What it cleans best
- Laundry detergent (primary component)
- Stripping buildup from laundry (washing soda soak removes detergent residue)
- Heavy grease on garage floors or outdoor furniture
- Removing rust stains
Safety
More caustic than baking soda. Wear gloves when handling in powdered form. Not for skin or food contact.
Where to buy cheapest
Arm & Hammer Super Washing Soda (3.5 lb box): $5–$8 in the laundry aisle. Hard to find in some regions — Amazon reliably stocks it.
Ingredient 5: Essential Oils (Optional But Useful)
What they add
Essential oils add fragrance and, in some cases, antimicrobial properties:
- Tea tree oil: Proven antimicrobial — add to bathroom and kitchen cleaners
- Lemon or orange: Fresh scent, mild degreasing
- Lavender: Calming scent, used in laundry and bathroom cleaners
- Eucalyptus: Fresh scent with mild antiseptic properties
How much to use
10–20 drops per 16 oz spray bottle. A little goes a long way — a 10 ml bottle lasts months in cleaning products.
Where to buy cheapest
Plant Therapy or NOW Foods essential oils offer the best quality-to-price ratio. Avoid ultra-cheap brands — low-quality oils smell synthetic. Shop tea tree oil on Amazon.
Ingredient 6: Rubbing Alcohol (Isopropyl Alcohol, 70%)
What it does
Fast-drying disinfectant and solvent. The secret weapon for streak-free glass and mirrors.
What it cleans best
- Glass and mirrors (eliminates streaks)
- Electronics surfaces (keyboards, phone screens)
- Sticky residue removal (labels, tape residue)
- Quick disinfection of high-touch surfaces
Safety
Flammable — keep away from flames. Good ventilation when using in quantity.
Where to buy cheapest
Pharmacy or grocery store: $3–$5 for 16 oz. Buy the 70% concentration, not 91% — 70% is more effective as a disinfectant.
