Pure Magic: Nancy Birtwhistle shares her eco-friendly cleaning and gardening tips

Nancy Birtwhistle shares some of her favourite homemade, eco-friendly cleaning products and gardening tips, including the recipes for her natural cleaner –  a.k.a ‘Pure magic’.

Nancy Birtwhistle not only won the fifth series of The Great British Bake-Off, but has built up a huge online following of devoted fans – including Gigi Hadid and Jonathan Van Ness – who love her sustainable, eco-friendly cleaning and gardening tips. Here she shares some of her cleaning recipes (including her famous 'Pure Magic' and cream cleaner) and gardening suggestions, to give you a taste of Green Living Made Easy, Clean & Green and The Green Gardening Handbook: three of the best books to help you live more sustainably.

Nancy Birtwhistle’s 'Pure Magic' (previously known as 'Toilet Magic')

You will need

200g citric acid

150ml just-boiled water

20ml eco-friendly washing-up liquid

10–20 drops tea tree oil

1 pint measuring jug

Small whisk

400ml glass bottle with spray attachment and screw top


Place the measured crystals in a heatproof measuring jug and pour over just-boiled water. Stir until the liquid is clear and the crystals have dissolved, then simply add the eco-friendly washing-up liquid and tea tree oil and mix well using a small whisk. Leave the liquid in the jug to cool completely and uncovered for a few hours then pour into a spray bottle and it is ready to use.



Nancy Birtwhistle's citric acid wash to extend the shelf-life of fruit

You will need

Citric acid, lemon juice or white vinegar

Large heatproof bowl

Sieve or colander

Plastic box or glass jar with lid


Put 10g citric acid (about 2 teaspoons) in a large bowl, add 60ml (2fl oz) boiling water and swirl around until it dissolves and the liquid looks clear. Add 400ml (14fl oz) cold water. Wash the berries in the solution in batches, swirling them around and using a slotted spoon to remove them and place them in a sieve or colander to drain. Your berries are now cleaned and prepped for a longer, fresher life. There’s no need to wash them again before using.


Nancy Birtwhistle's kettle descaler

Do not dispose of the citric acid you used to extend the shelf-life of your fruit. Instead, use it to descale your kettle with this recipe. 

You will need

80g citric acid for a thorough clean

1–2 lemons for regular maintenance


Half fill your kettle with water and boil. Unplug it, if electric, and stand the kettle in the empty sink (the citric acid will cause the water to bubble up). Add 80g citric acid and leave for half an hour. The limescale will dissolve. Pour away the liquid. Before pouring away the citric acid solution, tip the kettle on its side so that the water fills and dissolves any limescale build-up in the spout.


Nancy Birtwhistle's strawberry top vinegar

You will need

Knife

Large glass with a lid, sufficient to hold 500ml liquid plus strawberry tops 

Strainer

Jug

500ml vinegar bottle

Funnel

Paper coffee filter or square of kitchen paper

Sliced green tops from a punnet of strawberries (about 20-30 tops)

500ml of distilled white vinegar


After washing your strawberries, rather than hull them, slice off the very tops of the leaves with a tiny section of the fruit. Pop the tops into a jar. Once all of the strawberries have strawberries have been trimmed and transferred into the jar, pour over the vinegar, screw on the lid and leave in a cool place (not the fridge) for 2-3 days. 

After the standing time the vinegar will be tinged with a gorgeous strawberry colour and a fruity smell. Strain the vinegar from the tops using the strainer set over a jug. 

Take your clean vinegar bottle, pop the funnel into the neck and line it with either the paper coffee filter or fold a sheet of absorbent kitchen paper into four and open it out into a cone. Then pour the strained vinegar through the filter and allow it to drop into the bottle. 

Use in any recipe that calls for red wine vinegar, cider vinegar, white wine vinegar and use to make a simple vinaigrette for up to two months. 


Nancy Birtwhistle's eco-friendly fabric conditioner

You will need

200ml (7fl oz) white vinegar or Freshen-up Vinegar 

15ml (1 tbsp) vegetable glycerine 

10 drops organic essential oil (try a flowery one such as ylang ylang or lily of the valley) 


Mix and add 2–3 tablespoons to the fabric softener compartment for each wash.


Nancy Birtwhistle's cream cleaner

You will need

200g bicarbonate of soda

70ml vegetable glycerine

20ml eco-friendly washing-up liquid

a few drops essential oil for perfume (optional)

500ml jar or tub


Simply place all the ingredients into the jar or tub, stir to a thick smooth paste and it is ready to use. When making my first batch, I poured it into a reused plastic squeezy bottle, but I found that the cleaner was not free-flowing enough to run to the bottom of the bottle when nearly empty, so I now find a jar is much better. Perfect for granite worktops and sanitary ware, being non-acidic and only slightly abrasive. 


Nancy Birtwhistle’s eco-friendly oven shelf cleaner

You will need

2–3 cups washing soda

Hot water

Sink or plastic box large enough to hold your oven shelves


In a sink large enough to take your oven shelves, or a sturdy plastic box, measure 2–3 cups of washing soda. If your shelves are really grubby, make a double concentrate and use 4–6 cups. Pour in sufficient boiling water to cover your shelves. If you do two shelves your water needs to be about 3 inches (7cm) deep. 

Pop your metal shelves into the hot solution making sure they are submerged and leave them overnight. 

I have found that if the shelves are hot when submerged the cleaning is quicker and more effective, but you may want to avoid shelves being too hot if you are using a plastic box.

The next day lift your shelves out of the brown, muddy water and wipe clean – that’s it. 

You can pour the water down the drain knowing no harm is being done.


Note: If your oven shelves have been sprayed or coated with ‘self-clean’ substances, do not use this method. The chemical coating can be damaged by soaking. This method is not suitable for aluminium trays or shelves. Aluminium can be cleaned using bicarb or washing soda, but long soaks cause oxidization.


Nancy Birtwhistle’s eco-friendly carpet stain remover

You will need

Bicarbonate of soda

Warm water

Small bowl

Cloth


Mix a thin paste and dab it over the stain, massaging it in circular motions with gloved hands. The residual stain will lift and so will the odour. If you can air-dry the item, even better.


Note: When dealing with carpet stains, never be tempted to give the carpet a vigorous rub and scrub because this can damage the pile. I speak from experience here, as I once dived straight onto a stain with a cloth and a full jar of elbow grease. I rubbed and scrubbed at this stain, only to find when everything had dried that the stain had disappeared but was replaced by a permanently damaged scuffed carpet pile. Remember: however bad the stain, gently does it. 



Nancy Birtwhistle’s shrunken jumper fix

You will need

a large bowl 

the shrunken jumper

hair conditioner

2 tbsp white vinegar 

2 large ‘bath-size’ clean dry towels 


In a bowl large enough to take the woollen jumper when folded, give 2–3 squirts of hair conditioner and add the vinegar then fill with lukewarm water. Lay the folded jumper onto the bowl of water. No need to submerge it – leave it to absorb the water in its own time and sink to the bottom of the bowl, then leave overnight. The vinegar and hair conditioner will soften the woollen fibres, making them lax and pliable. The next day, pour the water off the jumper and gently squeeze it to remove the excess. Do not rinse, wring or spin.

The next day, pour the water off the jumper and gently squeeze it to remove the excess. Do not rinse, wring or spin. Lay a large clean towel onto a flat surface and on top place the very wet jumper. Gently pull at it lengthways and sideways, stretching the fibres as you go. Take your time in gently remoulding your favourite jumper to its original size and shape.

Once you are satisfied that it looks as it used to, take the towel and start rolling from the bottom, nice and tight, until the jumper is concealed in a huge towel and jumper sausage. Rolling tightly will extract much of the remaining moisture. When the towel feels quite wet, unroll and transfer the jumper to the second towel, which again has been laid out on a flat surface.

Nancy Birtwhistle’s plant feed with added benefit

Makes around 500ml. You will need

rubber gloves 

scissors

60g nettles (leaves and stalks)

clean, old plastic tub or similar with a lid

600ml cold water (rainwater is ideal)

old fine tea strainer

1-litre bottle with spray attachment

1 – 2 drops eco-friendly washing-up liquid

6 drops clove-bud oil

Wearing gloves, harvest the nettles with scissors. Select the young leaves because they contain more nitrogen that is quickly broken down in water. The leaves need to be 5 – 7 cm long. Pop them into a plastic tub that has a lid. Pour over the cold water, stir and push the nettles into the water using a gloved hand. Pop the lid on and leave outside and forget about it for at least a week (2 weeks is even better), stirring maybe once or twice during that time.

When ready to use (and I suggest you do this outside), take off the lid, give it a stir and the smell will send you reeling – it really is awful, but plants love it! Strain off the leaves, using simply the lid as an aid, then strain again using an old fine tea strainer. Fill the spray bottle, then add the eco-friendly washing-up liquid and clove-bud oil. Give it a good shake then spray away!

I avoid using this spray on my vegetables just before I want to eat them, though the spray will readily wash off so it's not a big deal if you do.
