How to Make Carpet Smell Good: DIY Guide
Nothing makes a home feel instantly welcoming like the fresh, clean scent that greets you as you walk in. But carpets — soft and cosy as they are — can easily hold onto smells from pets, food, shoes, and everyday life. If you’ve ever wondered how to make carpet smell good without relying on store-bought products, you’re in the right place. This easy, practical DIY guide will show you how to create your own carpet freshener using simple ingredients, while keeping it safely made and enjoyable for your home.
Why DIY Carpet Freshener Works
Carpets are like giant sponges for smells. Fibres trap tiny particles of dust, body oils, spilled drinks and pet accidents — and that can make a room feel less than fresh even after vacuuming. Commercial carpet fresheners often use synthetic chemicals and artificial fragrances that mask odours rather than neutralise them.
A homemade blend using baking soda and a fragrance oil will literally absorb odours rather than just cover them up. Baking soda naturally oxidises and neutralises lingering smells, while fragrance oils or chosen essential oils add that pleasant aroma you love.
🧼✨ This is the core of how to make carpet smell good at home — effective, natural, and customisable to your favourite scent profile.
Ingredients You’ll Need
To make one batch of your carpet freshener:
Baking soda (sodium bicarbonate) – a natural deodoriser that absorbs odours.
Fragrance oil – choose a scent you love.
A mixing bowl, spoon and a jar or shaker for storage and application.
Baking soda acts as your base, while the fragrance oil gives personality and depth. This pairing is the simplest effective way to refresh carpet fibres.

Step‑by‑Step: How to Make Carpet Smell Good
Here’s how to turn two humble ingredients into a carpet refresher that smells fabulous:
1. Measure Your Base
Pour about 490g of baking soda into a large, dry bowl. Adjust the amount if you want to make more or less — but this proportion gives a good balance of odour absorption with enough powder to spread easily.
2. Add Your Fragrance Oil
Add around 10g, IFRA permitting of your chosen fragrance oil into the baking soda. If you prefer a lighter scent, start with half and increase gradually. Using too much fragrance oil can cause the powder to clump and reduce its effectiveness.
💡 Pro tip: If you have one of House of Scent's 10g tester bottles, it’s a perfect size to use directly for this recipe. For larger bottles, use a digital scale to ensure accurate measurement so you stay within safe usage limits, especially when following IFRA guidelines.
3. Mix Thoroughly
Stir vigorously until the fragrance oil is evenly dispersed throughout the baking soda and you see no large clumps. A well‑mixed powder means a more consistent scent release when you apply it to the carpet.
4. Store It Right
Transfer the finished carpet freshener into a jar with a shaker lid (like a spice jar) or any container with small holes for even sprinkling. Seal it well and label it with the scent name — especially if you plan to make several blends for different rooms.
5. Sprinkle Generously
Lightly dust your carpet with the mixture, paying extra attention to high traffic areas or spots where odours seem strongest (like near pet beds or hallways). Avoid over‑loading — a light, even layer works best.
6. Let It Sit
Allow the powder to rest on the carpet for 15–30 minutes so it can absorb smells and release fragrance. For particularly stubborn odours, you can leave it for up to 2 hours.
7. Vacuum It Up
Use your standard vacuum cleaner to remove all powder from the fibres. This final step lifts odours while leaving a delightful, lingering scent behind.
Safety First: IFRA and DIY Fragrance Use
When you’re creating scented products for your home — even carpet fresheners — keeping safety front of mind is important, especially when learning How to make Carpet smell good in a way that’s both effective and responsible.
What Is IFRA?
The International Fragrance Association (IFRA) publishes safety standards for fragrance ingredients based on scientific evaluation. These guidelines help ensure that fragrance oils and their components are used at concentrations that minimise risk of irritation or adverse reactions.
Why IFRA Matters Here
IFRA standards categorise product types and specify maximum usage levels for fragrance materials.
Following these limits helps reduce the likelihood of irritation — especially in environments shared with children, pets or people with sensitivities.
Always keep and refer to the IFRA Conformity Certificate that comes with your fragrance oil — it tells you the safe usage level for different applications.
If you’re using pure essential oils instead of a formulated fragrance blend, know that some essential oils contain components that may be restricted at certain concentrations. You can often find safety data sheets or consult IFRA’s published standards for more detail.

Tips for Better Results
Use quality oils: Higher‑grade fragrance oils tend to last longer and disperse more evenly in baking soda than cheaper alternatives.
Patch test: For delicate or light‑coloured carpets, test a small, hidden area first to ensure no discolouration.
Refresh regularly: Sprinkling every 1–2 weeks helps maintain a consistently pleasant smell.

FAQs
What is carpet freshener?
Carpet freshener is a product designed to neutralise and absorb odours trapped in carpet fibres rather than simply masking them. It is usually sprinkled onto the carpet, left to sit for a short time, then vacuumed away. DIY carpet fresheners typically use baking soda as the base because it naturally absorbs smells, with fragrance oils or essential oils added to leave a pleasant scent behind.
How often should I use homemade carpet freshener?
For most homes, using a DIY carpet freshener every 1- 2 weeks is ideal. High-traffic areas or homes with pets may benefit from more frequent use. Regular vacuuming combined with light, consistent freshening will help maintain a clean-smelling carpet without product buildup.
Is DIY carpet freshener safe for pets and children?
When used responsibly, a baking soda-based carpet freshener can be safe for homes with pets and children. Always follow IFRA usage limits, avoid over-fragrancing, and ensure the powder is fully vacuumed up after use. Keep pets and children out of the room while the powder sits on the carpet, and never allow them to ingest the mixture directly.
