DIY cleaning product recipes
CostFree to Low
Includes: Common pantry ingredients (vinegar, baking soda, lemon, castile soap), essential oils, glass jars or spray bottles. Example: A €10 bottle of castile soap can make litres of multipurpose cleaner, laundry soap, or dishwashing liquid.
What it is
A typical household spends around €80 a year on sprays and creams that are mostly water in a plastic trigger bottle. The pantry version costs a fraction of that and does almost everything the branded one does.
DIY cleaning recipes turn a short list of staples into a full kit. White vinegar, bicarbonate of soda, washing soda, castile soap, and a few essential oils handle most of what a kitchen and bathroom actually need. You mix them into glass bottles, label them, and the cupboard under the sink stops looking like a recycling problem.
The first recipe almost everyone tries is an all-purpose spray. Dr. Bronner's Sal Suds, a little water, a splash of vinegar, ten drops of lemon oil. It cuts grease, wipes down tiles, and smells clean rather than chemically perfumed. After that people branch out. A bicarb paste for the hob. Citrus vinegar for glass. Washing soda for laundry pre-treatment. Each one is a five-minute job.
The honest limit is heavy disinfection. For a hospital you want something stronger. For a normal kitchen these recipes are more than enough, and most people who switch never buy the swimming-pool spray again.
How it works
The base most recipes share: distilled white vinegar, bicarbonate of soda, and a mild liquid soap, plus water and a few drops of essential oil if you want scent. Those four cover the majority of household surfaces between them. Vinegar cuts grease and limescale on glass and taps, bicarb scours and deodorises, and a drop of castile soap lifts general grime off worktops.
The combination that trips people up is vinegar and bicarb together in the same bottle. They neutralise each other into salty water and a brief, satisfying fizz, which feels powerful but leaves you with a spray that does almost nothing. Use them in sequence instead, never premixed: sprinkle bicarb, spray vinegar, let it foam in place, then wipe. For an all-purpose spray, half water and half vinegar with a teaspoon of soap in a 500ml bottle handles most jobs.
Storage matters more than people expect. A 500ml glass spray bottle does not degrade with acidic ingredients the way cheap plastic does over months of use, and anything with castile soap is best mixed in small batches because soap and acid slowly separate. Label every bottle with contents and date, because three clear sprays on a shelf become indistinguishable within a week.

FAQs
For everyday messes, yes. An all-purpose spray of Sal Suds, water, and a few drops of tea tree oil cuts grease and bathroom grime without any drama. Bicarbonate of soda paste scrubs sinks and hobs better than most cream cleaners on the shelf. Where the homemade versions fall short is heavy disinfection and old set-in stains. For normal domestic use, they hold their own.
They do different jobs. Sal Suds (the blue bottle) is the surface and floor concentrate, and a single capful in a litre of water handles most cleaning. The liquid castile soaps with the long printed label are gentler, meant for skin, hand wash, or pet baths. For scrubbing the house, reach for Sal Suds.
No, and this catches a lot of people out. Vinegar is acidic and castile soap is alkaline, so combined they break the soap back down into a curdled white film that cleans nothing. Keep them in separate recipes. Vinegar sprays for glass and surfaces, soap solutions for floors and general washing.
It depends on what is in them. Vinegar and bicarb mixes last months because neither spoils. Anything with fresh citrus juice or plant material should be used within a week or two, since it can grow mould. Label every bottle with the date you made it. A simple piece of masking tape and a marker saves a lot of guessing later.
Yes, by a wide margin over time. A typical household spends around €80 a year on sprays that are mostly water in a plastic trigger bottle. The pantry staples (white vinegar, bicarb, washing soda, a bottle of Sal Suds) cost maybe €15 to set up and refill a kit for the better part of a year. The savings build quietly with every bottle you do not buy.
⚠️ Safety note: This page mentions lye soap and ash water as historical cleaning agents. Do not try to make homemade lye from wood ash for cleaning. The concentration is unpredictable and can cause serious burns. Never combine cleaning products containing bleach with vinegar or ammonia, as the fumes are dangerous.
