Get your kids excited about cleaning the house with this selection of all natural easy to prepare cleaning products!

I’ve included lots of educational links including science experiments using the cleaning ingredients to extend the fun.

And a recipe for really quick lemonade to enjoy after a successful mission.

A whole day of homeschool and the house is fresh and clean afterwards…Almost unheard of!

Kids will have great fun stirring up magical potions to create a sparkling clean home. And will learn many science concepts along the way.

Homemade cleaners are great for the environment and your families health. No harmful chemicals are let loose around your home.

Good news for family members with asthma, allergies or other respiratory problems.

Also means less waste and packaging.

But you don’t have to compromise on cleanliness as natural ingredients such as lemons are antibacterial, antiviral, antimicrobial, antiseptic and antifungal..phew!

Luckily they’re not anti-human…in fact they are so super good for us as they are anti-inflammatory, detoxifying and a natural antihistamine.

As well as being full of antioxidants, vitamins and minerals.                                                     

Vinegar is another wonder ingredient and some scientists claim that vinegar as a cleaner is more effective than chemical shop bought varieties.

Vinegar can eliminate e-coli, salmonella and shigella bacteria.

I remember learning about the shigella bacteria at cookery college and it was not pleasant!

You might think spraying vinegar left right and centre around your home will leave your home smelling like a fish and chip shop.

But actually vinegar is a deodorizer and its smell will evaporate as your cleaning mix dries.

To store your natural cleaners recycle any spray bottles you might have. I had a couple left over from when I use to buy antibacterial spray.

Make sure you wash thoroughly to ensure any chemicals have completely gone.

Or invest in some inexpensive garden spray bottles…at least you’ll be reusing them often.

Little glass jars saved from recycling could also be utilised. Even washed out shampoo/washing liquid bottles could work as storage for your kids new creations.


(This recipe could also be used to clean shower heads, taps, sinks anything really. Though if your using lemon don’t use it on natural stone or brass)

1 cup of white vinegar                                                                                           

4 cups of water

Tbsp of fresh lemon (not essential but nice)

1-2 tbsp bicarbonate of soda (depending on how many windows cleaning)

  1. Mix white vinegar and water together. If required use a funnel or just pour into your storage bottle.
  2. Using a damp cloth sprinkle some bicarbonate of soda onto the cloth and wipe into the windows. Its helps remove dirt etc.
  3. Spray windows with the vinegar-water mix and give windows a good rub
  4. When dry buff up with a cloth to prevent any streaks


Get your kids to work their magic and unblock your sinks with a bit of chemistry!

Tip 1/2 cup of baking soda down the blocked sink and then 2 cups of vinegar and watch the volcanic froth. Leave for 30 minutes and pour hot water down.

If its not blocked too much it should clear.


  1.  Place 1 cup of hot water in your spray bottle
  2.  Add 3 tbsp bicarbonate of soda and give it a good shake                                       
  3. Add some drops of your favourite herb essential oil
  4. Spray a little on anything you want to freshen up such as sofas/clothes/air

NOTE: Some essential oils are harmful to pets so best to check before using. Lavender helps calm pets so could be good one to use for this air/fabric freshener.

Also lemongrass and citronella helps protect pets against ticks and fleas so another good one to use about the house if you have pets. For more info I’ve included a link below.


Your kids will love this one! If your sofa needs a freshner up then throw bicarbonate over it, rub it about and leave for at least half an hour before hoovering.


Squeeze the juice of 1 lemon and pour down the toilet. Use a toilet brush and scrub. Lemon juice is non-toxic, antibacterial,antiseptic and possesses natural bleaching abilities. Or add 1/2 cup of vinegar to the toilet, let steep for 30-60 minutes. Clean with scrubbing brush and flush.


  1. 1/2 cup of vinegar
  2. 1 1/2 litres of warm water
  3. few drops of essential oil (pet friendly if necessary)

Mix altogether in mop bucket. (Don’t use vinegar on marble or stone floors)


  1. One cup of vinegar
  2. Enough water to fill up your spray bottle
  3. 1 tbsp of squeezed lemon juice
  4. Tbsp of grated lemon peel. Could use lime, orange or grapefruit peel.

Mix all together and leave to steep for a few hours.

Use this cleaner for bins, window sills, worktops/surfaces, dining-table, hard chairs, non-electronic toys, door handles, skirting boards, anything really!


  1. 3 Tbsp bicarbonate of soda
  2. 2 pints of warm water

Mix together and use to wash and freshen up the inside of fridge. Removes any smells.

Anything stainless steel in your kitchen will come up sparkling and shining if cleaned with this mix.

CHOPPING BOARDS: To freshen up chopping boards and kill bacteria, simply slice a lemon in two then use one of the pieces to wipe over the board. Use the leftover lemon to magically clean toilet and kitchen taps, just rub it over and witness the sparkle! Can also use sliced lemon to thoroughly clean a cheese grater just rub over and rinse.


  1. 1 cup of olive oil/linseed/vegetable (can use old oil that’s not good for consumption if you have any lurking in back of cupboard)
  2. 1/4 cup of vinegar
  3. Few drops of essential oil or tbsp lemon juice

Mix all together and rub into wood in circle movements. Buff up with another dry cloth.


  1. 3 Tbsp liquid castile soap
  2. 2 Cups of warm water
  3. 2 Tbsp vinegar
  4. 2 tsp glycerin (can buy either in chemist or amazon)

Mix all together into a jar and shake to combine. When washing dishes use about a tbsp of mix in warm water. Castile soap is all natural and vegetable based with no harmful chemicals.


To magically clean any copper kitchen implements or decorations such as vases, squirt a Tbsp of tomato ketchup onto a cloth and then sprinkle a tsp of salt on ketchup and use this mix to freshen up and remove any blemishes.


To clean silver objects, mix Tbsp of bicarbonate of soda with Tbsp of water to a thick paste. Rub this mix over the silver to bring back its shine. Rinse under water and buff up with a cloth.

GOLD JEWELRY: Steep your gold jewelry in a cup with enough vinegar to submerge. Use a toothbrush if necessary to rub. Leave for 15 minutes. Rinse and buff up.

BRASS CLEANER:  Squirt a Tbsp of Tomato ketchup onto a cloth and rub onto the brass object. Rinse out the cloth and wipe clean the object. Polish up with a dry cloth.

NOTE: Store your mixes in labelled bottles/jars in a dark place. Ingredients can settle/separate so just give a little swish before using.



  • 6 Squeezed lemons, about 200ml juice(To loosen up the juice roll the fruit firmly on your worktop.If you don’t have a juice squeezing implement then just use a tablespoon to dig into a halved lemon and move it about and it’ll squeeze the juice out. Discard the pips)
  • Alternatively use limes, grapefruit or oranges or a mix
  • 50-100 g sugar (depending on how sour/sweet you like it)
  • 800 ml water still or sparkling depending on how you like the lemonade

In a jug or mixing bowl, add the sugar and lemon juice and mix until thoroughly dissolved. Taste a little and if not sweet enough for your liking add a little more sugar.Add the water and stir thoroughly.

Chill in fridge till after your magical cleaning mission.
