Homemade cleaning products: 3 recipes that cover most tasks

You can make effective cleaning products at home using ingredients you probably already have. Vinegar, bicarbonate of soda and castile soap handle most household cleaning without the single-use plastic bottles or harsh chemicals. Ecomojo walks through three core recipes that work across kitchens, bathrooms and hard surfaces, plus what each one does best.

Why homemade versions reduce waste

Shop-bought cleaners arrive in plastic spray bottles, most of which aren't refilled. The liquid inside is largely water, shipped across the country in heavy packaging. Making your own cuts out that cycle: you mix concentrates with tap water in a bottle you already own, then refill it as many times as the bottle lasts.

The ingredients come in larger containers or loose form, often with less packaging overall. Bicarbonate of soda is sold in cardboard boxes, white vinegar in glass or larger plastic bottles you can reuse for storage, and a single bar of castile soap lasts months. You're also avoiding the synthetic fragrances and thickeners added to make commercial products look and smell a certain way.

All-purpose spray with vinegar

This handles worktops, sinks, tiles and most hard surfaces. White vinegar cuts through grease and dissolves limescale; the acetic acid disrupts bacteria without leaving a harmful residue.

Mix equal parts white vinegar and water in a spray bottle – a 500ml bottle takes 250ml of each. Add ten drops of essential oil if you want a scent, though it's optional. Shake before each use. Spray the surface, leave it for a minute on stubborn marks, then wipe with a cloth. The vinegar smell fades as it dries.

Where not to use it: avoid natural stone worktops such as marble or granite, as acid etches the surface. Don't use it on waxed wood either. For those, plain water and a drop of castile soap works better.

Variations for different jobs

Boost the formula for glass and mirrors by raising the vinegar proportion to two parts vinegar, one part water. It leaves fewer streaks. For a thicker spray that clings to vertical tiles, dissolve half a teaspoon of cornflour in the water before adding the vinegar – shake well each time, as it settles.

Bicarbonate scrub for stuck-on grime

Bicarbonate of soda is mildly abrasive without scratching most surfaces, and it neutralises odours. Use it as a paste for sinks, baths, hobs and oven doors.

Put three tablespoons of bicarbonate in a small dish or jar. Add water a teaspoon at a time, stirring until you have a spreadable paste. Apply it to the surface with a cloth or an old toothbrush, scrub gently, then rinse. For baked-on oven spills, spread the paste thickly, leave it for 15 minutes, then scrub and wipe.

In the bathroom, bicarbonate shifts soap scum from taps and shower screens. Sprinkle it dry into the toilet bowl, scrub with a brush, then flush. It's safe for septic tanks and doesn't leave a chemical film in the pipes.

Castile soap solution for floors and greasy surfaces

Castile soap is made from vegetable oils with no synthetic detergents. A little goes a long way, and it rinses clean without a sticky residue. Use it for mopping floors, washing painted walls or tackling kitchen grease.

For a bucket of floor wash, add one tablespoon of liquid castile soap to four litres of warm water. Mop as usual; no need to rinse unless the floor feels tacky. For a general-purpose spray, mix one teaspoon of castile soap into 500ml of water in a spray bottle. Shake gently before use – it doesn't need vigorous shaking like the vinegar mix.

On greasy hobs or cooker hoods, spray the castile solution, let it sit for a few minutes, then wipe. The oils in the soap break down cooking grease more effectively than vinegar alone. You can add a few drops of tea tree or lavender oil for scent, though plain castile has a mild, clean smell of its own.

Getting started: a simple sequence

1. Find one spray bottle you already have, or buy a reusable glass or sturdy plastic one. Label it clearly so it's never mistaken for something else.
2. Buy white vinegar, bicarbonate of soda and liquid castile soap. All three are available in supermarkets; castile soap is sometimes shelved with hand wash or eco products.
3. Make the all-purpose vinegar spray first – it's the most versatile. Use it for a week to see where it works and where you need the other recipes.
4. Mix small batches. The vinegar spray keeps for months, but the castile solution can separate if it sits too long. Fresh is easier.
5. Keep one cloth for each product, or rinse thoroughly between uses. Vinegar and castile soap don't react badly, but mixing them in the bottle reduces the effectiveness of both.

What these recipes don't do

Homemade cleaners work well for regular household cleaning, but they're not disinfectants in the medical sense. Vinegar reduces bacteria, yet it doesn't kill all pathogens the way hospital-grade products do. For most homes, that level isn't needed day to day. If someone in the house is ill or you're cleaning up after raw meat, you might want a stronger option for that specific task.

They also don't foam or thicken like commercial cleaners. Foam is a marketing trait, not a sign of cleaning power, though it takes a few uses to trust that a thin liquid is working. Thecastile solution is the only one with any lather, and even that is modest.

Storing and labelling

Label every bottle with its contents and the date you mixed it. Even if you think you'll remember, a bottle of clear liquid looks identical to water or leftover juice cordial. Write the recipe on the label or keep a note in your phone so you can remix without hunting for instructions.

Store bottles out of direct sunlight, which can degrade essential oils and weaken vinegar over time. A cupboard under the sink or in a utility room works. Keep them away from children and pets – these are safer than many shop products, but castile soap and concentrated vinegar still cause irritation if swallowed or splashed in eyes.

Comparing the three core recipes

When to buy instead of making

Not every task suits a homemade cleaner. Limescale removers for heavily scaled kettles or shower heads often need a stronger acid than vinegar provides. Mould on silicone sealant sometimes requires a specialist fungicide. Oven cleaners for serious carbonised build-up work faster than bicarbonate, though the paste handles light to moderate grime.

Weigh the trade-off: a single plastic bottle of a targeted product you use twice a year might be the practical choice, especially if the homemade version doesn't solve the problem and you end up buying the commercial one anyway. The goal is reducing waste where it makes sense, not replacing every product regardless of whether the swap works.

Adjusting recipes to your water

Hard water affects how castile soap behaves. In areas with high mineral content, castile can leave a white film or curdle slightly when mixed with water. If that happens, use distilled water for the castile solution, or reduce the amount of soap – try half a teaspoon per 500ml instead of a full teaspoon. The vinegar spray isn't affected by water hardness.

Soft water areas get more lather from castile soap, so you may need even less. Start with a smaller quantity and add more only if the cleaning power feels weak.

Building confidence with swaps

Switching from shop-bought to homemade cleaners often feels uncertain at first. The bottles look different, the consistency is thinner, and there's no advertising to reassure you it works. Give each recipe three or four uses before deciding. Most people find the vinegar spray handles daily wipes as well as anything they bought, and the cost difference becomes obvious quickly.

If one recipe doesn't suit your household, that's useful information – focus on the ones that do. Some people use homemade for most tasks and keep one commercial product for the job that never quite works with DIY versions. That's still a significant cut in plastic and packaging over a year.

Scaling up or down

The recipes here make 500ml or a single bucket's worth. Double or halve the quantities as needed, keeping the proportions the same. A larger bottle of vinegar spray saves time if you clean often, but mixing a small batch first lets you test the formula and adjust the scent or strength before committing to a litre.

Bicarbonate paste is always made fresh in the amount you need for that session. It dries out if stored, and a jar of old paste is harder to use than a quick two-minute mix. Keep the dry bicarbonate in its box, tightly closed, and it lasts for months.
