These Blank Canvas Fizzies are PERFECT for so many applications:
- In a steam bath or as shower drops for congested airways;
- In the bath for a fun time for kids, or to help them with relaxation or congestion;
- As toilet-cleaning drops (they work wonders with a light scrub);
- In a foot spa;
…and the list goes on, and on, and on!!
I do have a little secret to share though, this Blank Canvas Fizzies recipe is exactly the same as my Fizzy Bath Drops.
BUT, this recipe is like a blank canvas.
Store your drops in a container or jar and add your choice of essential oils just prior to use. It’s so versatile and even a makes for a beautiful gift to give, perfectly paired with a bottle of lemon, peppermint or lavender essential oil for someone’s birthday, or maybe with eucalyptus or lemon for an under-the-weather friend.
I’ve chosen to call this recipe Cleaning Fizzies in my new book, Naturally Inspired, but don’t be confused – it’s all basically the same 😉
BLANK CANVAS FIZZIES
Makes: 460 g | 16.2 oz (approximately 15 small, 5 large) Prep time: < 5 min. (allow 24 hours to set)
Ingredients
300 g | 10.6 oz sodium bicarbonate (bicarb)
130 g | 4.6 oz citric acid
30 g | 1.1 oz carrier oil (fractionated coconut oil and sweet almond oil are popular choices)
2-3 drops of essential oils (per use)
My choice of essential oils…
This varies depending on the intended use.
My favourite essential oils in this recipe are as follows:
– congested airways (in the shower, facial steam, bath) – lemon, eucalyptus and tea tree.
– relaxing bath – lavender, frankincense, orange, ylang ylang, vetiver etc.
– toilet cleaner (drop in the toilet) – clove, tea tree and lemon.
Remember: don’t be limited by my suggestions. Use oils that fit your budget, or those that you already have in your collection. Read here for more information.
Extra equipment required…
Silicone moulds
Method
1. Add sodium bicarbonate and citric acid to a bowl and mix until combined.
2. Add carrier oil and mix until combined. Mixture should just hold form when squeezed together. If it isn’t holding together, add an extra teaspoon of carrier oil and mix again.
3. Spoon mixture into moulds and press down firmly until full.
4. Leave to set for 12-24 hours in a cool and dry place. After this time, turn moulds upside down and gently tap the bottom – fizzies should fall out easily.
5. Place on a tray or sheet of baking paper and leave to dry for a further 24 hours before storing in container of choice.
Thermal Appliance Method
1. Add sodium bicarbonate and citric acid to thermal appliance bowl and mix for 5-10 seconds on medium speed. Scrape down sides and repeat if required, until ingredients are combined.
2. Add carrier oil and mix for 5-10 seconds until combined. Mixture should just hold form when squeezed together. If it isn’t holding together, add an extra teaspoon of carrier oil and mix again.
3. Spoon mixture into moulds and press down firmly until full.
4. Leave to set for 12-24 hours in a cool and dry place. After this time, turn moulds upside down and gently tap the bottom – fizzies should fall out easily.
5. Place on a tray or sheet of baking paper and leave to dry for a further 24 hours before storing in container of choice.
To Use
Add essential oils directly to one fizzy (see recipe notes below for ideas for various applications). Drop into water (basin, bath, toilet etc.) and allow to fizz. Store in an airtight container, in a cool, dry place.
Recipe Notes
To colour these fizzies, you can use food colouring (natural is obviously my choice – beetroot powder or spirulina are my go-to’s); powder is the best option if you want to avoid the risk of premature fizzing.
Did you know that adding one teaspoon of vitamin C powder to bath water while it is filling, helps to neutralise the chlorine present in unfiltered tap water, and I highly recommend getting some. For more info about the effects of chlorine, head over to the Super Soak – Bath Salts recipe.

We absolutely love these blank canvas Fizzies, we use for the toilet and the dishwasher, the kids love to make them with me (2 & 4 years old), I love that it is safe for them to help me make my cleaning products. My 4 year old loves to put one in the toilet and give it a scrub
We flush with bore water, and the scale build up in the loo was something I could never get ontop of.. think me with a putty knife chipping it off.. it also seemed to absorb smells so my loo was absolutely embarrassing..
I was sceptical, dropped one of these in before I went to bed, gave a light brush in the morning for a couple of days, the scale literally wiped off the loo and hasn’t been back. Now I drop one in every 3-4 days and leave overnight.
I am so happy I found such a simple recipe! And because they’re blank, when someone is a bit stuffed up, I can add EO and drop in the shower aswell for a steamer!!
This would be my absolute favourite of Krissys recipes!
I make these versatile drops on constant rotation. Love how they do more than one job in the house. Love trying different essential oils too.
These are a standard in our house. Everyone gets to choose their own essential oil combos for their bath as they use them. And they are awesome in the toilet. (And so fun to watch fizz in the toilet)
It is important to not overdo the moisture when making them and I always leave them a fair while to properly set – giving them a good press every time I walk past them.
We just love the Blank Canvas Fizzies! With lemon essential oil (one of the cheapest EO’s) we use them in the dishwasher & as toilet fizzies to clean. Converted here!
