Surface & Material Cleaning Engine

Clean is an AI tool for cleaning, maintaining, restoring and recovering physical objects, materials, surfaces and spaces.

Name what needs attention, what the object is made of, the current condition and the result required, and Clean determines what to do and which methods are appropriate.

Where a cleaning attempt has already gone wrong, Clean identifies what happened and whether the material can still be recovered.

cleaning method selector

• Identifies cleaning methods that suit the material, the condition and the required result.

stain identifier

• Identifies an unknown stain, residue, deposit or buildup from where it sits, how it looks and how it behaves.

stain removal guide

• Determines which removal chemistry lifts a given stain from a given substrate, and whether the stain is fresh, dried or already set by heat or a previous attempt.

buildup and deposit removal guide

• Handles scale, film, oxidation, carbon, fouling, tarnish and adhesive residue that accumulate rather than spill.

surface cleaner selector

• Determines the method for the named material rather than a general-purpose one, across textiles, wood, stone, metals, plastics, glass, ceramics, coatings, painted surfaces, electronics, paper and composites.

material compatibility checker

• Checks what the material tolerates before recommending chemicals, heat, water, solvents, abrasives, pressure or steam.

chemical compatibility checker

• Checks the cleaning chemistry against the substrate, the coatings, the seals and the operating conditions it will meet.

product compatibility checker

• States which products can be used on the object, which will damage it, and which must never be combined with each other.

equipment compatibility checker

• Checks a cleaning or disinfection product against a named machine, instrument or appliance before it is applied.

disinfectant compatibility checker

• Checks a disinfectant against the surface, the material and the contact time the situation requires.

cleaning and disinfection protocol tool

• Separates sanitising, disinfecting and sterilising, and returns the protocol for the standard the situation actually requires.

cleaning chemistry guide

• Names the mechanism doing the work — dissolving, emulsifying, oxidising, chelating, neutralising, enzymes, heat or abrasion — and matches it to the contaminant rather than to product strength.

homemade cleaner guide

• States what vinegar, bicarbonate, salt, lemon, alcohol and soap actually do, what they are safe on, and where a DIY method goes wrong or becomes dangerous.

mixed-material cleaning guide

• Determines the safest method for an object combining several materials, coatings, adhesives or finishes, where the most vulnerable exposed layer governs what can be used.
• Reads how the materials interact with each other and with the environment they sit in.

spot test planner

• Establishes where and how to test before committing to a method on the whole object.

equipment cleaning guide

• Handles machinery, tools, instruments, food and medical equipment, appliances and vehicles, including the machines that contaminate themselves.

maintenance planner

• Builds cleaning routines, protective treatment, drying, storage and coating schedules that keep ordinary use and environmental exposure from becoming damage.

preventive care planner

• Identifies the conditions producing wear, buildup, corrosion, drying or staining, and what changes them.

conservation decision support tool

• Selects reversible, low-risk, minimum-intervention methods for fragile, valuable and irreplaceable objects, and identifies where the wear is part of the object.

condition assessment tool

• Distinguishes removable contamination from etching, fading, scratches, cracking, corrosion, oxidation and other deterioration of the material itself.
• States whether damage is irreversible and whether it is still active.

restoration assessment

• Determines whether an object affected by grime, staining, corrosion, mould, residue, poor storage or neglect can be recovered, and what recovery would involve.

salvage and recovery guide

• Handles objects damaged by water, smoke, fire, flood or collapse — what can be cleaned or dried now, what must be stabilised first, and what order the work goes in.

cleaning troubleshooting guide

• Diagnoses a cleaning attempt that failed or made it worse, identifying whether the contaminant was misidentified, the chemistry was wrong, the sequence was wrong or the material was misunderstood.

mould assessment tool

• Reads the extent, the surface and the moisture behind it, and states whether this is a clean-up, a remediation or a building problem.

mould remediation guide

• Returns the removal method, the containment and drying required, and the moisture source that has to be corrected for it not to return.

recurrence and source control guide

• Identifies the underlying condition recreating recurring odour, stains, scale, corrosion or buildup, and what has to change for it to stop.

cleaning safety checker

• States what must never be mixed, what ventilation is required, and what applies for flammability, food contact, children, pets and disposal.

professional referral guide

• Identifies where professional conservation, remediation or restoration is safer than further cleaning.

low-resource cleaning guide

• Adapts a method when products, equipment, water, electricity or specialist supplies are unavailable.

traditional cleaning methods guide

• Covers how things were cleaned before modern products — ash, sand, clay, lye, oil and mechanical action — and where those methods still hold up.

cleaning planner

• Sequences a larger job by deciding what needs cleaning, what can be restored, what should be discarded, and what order the work goes in.

decluttering decision tool

• Sorts possessions in a neglected or cluttered space into keep, clean, repair, donate, sell and discard, against the time, space, disposal options and physical resources actually available.

Enter the object, material, surface or space needing attention, along with what the object is made of.

Name the contaminant where known. Blood, grease, wax, ink, mould, mineral scale, adhesive and soot each require a different method.

Describe the current condition when a method has already been tried. A cleaner already used, a stain that went through the dryer, and mould that returned after cleaning each change the next step.

Include practical constraints: limited water, limited products, unavailable equipment, delicate materials, children or pets, food-contact surfaces.

State the result required, because removing a stain, keeping an object in routine condition, restoring a neglected item and sorting a cluttered space call for different approaches to the same object.

why a method that works on one material damages another

Heat, water, abrasives and chemicals each change what is safe to use. Acid that brightens copper etches marble. Solvent that lifts glue off steel clouds acrylic. Water that rinses a plate swells wood and lifts veneer. And it is usually the surface layer that decides, not the material underneath — paint, lacquer, wax, sealant or anodising sets the rules, not the metal or wood beneath it.

why an effective cleaner is not a safe cleaner

A cleaner works by attacking a bond. Whether it stops at the dirt depends on what is under the dirt. Bleach whitens grout and destroys wool, because the same reaction that breaks the stain breaks the fibre. Caustic strips baked-on fat and blackens aluminium. The question is never what removes this. It is what removes this and leaves the rest.

why the contamination decides the method

Grease, scale, protein, rust, wax, mould, soot and glue all come off differently. Grease needs something that emulsifies. Scale needs acid. Protein needs enzymes or cold water, because heat sets it for good. Rust needs acid or electricity. A degreaser will not touch limescale at any strength. When a product does nothing, it is usually the wrong mechanism rather than too weak.

why the state of a stain matters as much as the stain

The same spill is three different problems. Fresh, it sits on top and lifts easily. Dried, it has bonded in and needs rewetting first. Set by heat — a dryer, an iron, a hot wash, the sun — it has changed chemically and may never come out. So the first question is not what the stain is. It is what has already been done to it.

why cleaning and maintenance are different jobs

Cleaning removes dirt. Maintenance keeps the conditions that cause dirt, wear and corrosion from taking hold. They pull in opposite directions. Cleaning is occasional and harsher than the object wants. Maintenance is routine and protective. Most things that need a heavy clean are things that stopped being maintained — and every heavy clean leaves the surface a little more open than before.

why restoration begins where cleaning stops

Dirt sits on the surface. Damage is the surface. Cloudy marble after an acid spill is not dirty, it is dissolved, and no cleaner brings it back — it has to be reground and polished. Telling the two apart decides whether more cleaning helps or just takes off more material.

why cleaning is the one thing you cannot undo

Most treatments can be reversed. Glue can be dissolved, a coating stripped, a repair redone. What you remove is gone. That is why the safest approach with anything valuable is the least that works. And it is why you settle first whether that layer is dirt or part of the object — patina, original finish, honest wear — because afterwards the answer no longer matters.

why the same problem keeps coming back

Mould needs damp. Scale comes from the water. A stain that reappears is often coming up from deeper in the material. Clean the visible part and the cause stays. How fast it returns tells you which: days means something is still feeding it, months means the surface is holding a reservoir, seasonally means a condition that comes and goes.

why stronger is not better

Harsh chemicals, abrasives, heat and pressure can take the problem and the surface together. Start mild and you can escalate. Start hard and you cannot go back — the gentle option is gone once a surface is etched or stripped. Pressure washing brick drives water into the wall and removes the weathered skin protecting it. A wire wheel takes rust and metal in the same pass. A mild method that fails costs an afternoon. A strong one that overshoots costs the object.

why mixed materials need more than one check

The vulnerable part is rarely the obvious one. It is the glue holding the shoe together, the paper label under the tin, the felt in the drawer, the rubber behind the trim. Whatever is most fragile sets the method for the whole object. Materials also settle against each other over years, so wetting one part can unsettle something that was stable.

why a damaged object is stabilised before it is cleaned

After water or fire the material is still moving — swelling, corroding, growing mould. Clean it mid-reaction and you set the damage instead of removing it. Wet paper stuck together is separated wet or frozen and dealt with later, never dried and pulled apart. Soot comes off dry, because water turns it into a stain that sinks in. The first few hours matter more than the method you choose afterwards.

why household ingredients are not automatically mild

Vinegar is an acid and etches stone. Bicarbonate is an abrasive and scratches soft finishes. Salt cuts. Lemon bleaches in sunlight. They work because they are chemically active, which is the same reason they damage things. And the two most repeated home remedies are the worst of both worlds — vinegar and bicarbonate neutralise each other into salty water, while vinegar and bleach make chlorine gas.

why the same object can need a different answer

An object in use, one being sold, one being kept and one being studied are four different jobs. A working cast-iron pan wants a maintained surface. The same pan in a collection wants leaving alone. A tool going back to work can be stripped to bare metal. The same tool as a record of how it was made cannot. What you want out of it changes the method more often than the material does.

why the old methods still work

Ash, sand, clay, lye, oil and plain mechanical action cleaned everything for thousands of years, and they did it by the same chemistry we use now — lye is alkali, ash is both abrasive and alkaline, clay absorbs oil, sand abrades. They are still the right answer when there is no power, no water to spare, or a surface that modern products would strip.

why decluttering is not cleaning a bigger room

Cleaning has a right answer. Sorting has a cost attached to every item, and the cost is different for a broken chair, a box of photographs and a tin of something nobody can legally bin. That is why a neglected space stalls. Not the cleaning — the fact that every object is being decided on its own, with no order to work through.
