Highchair Cleaning Test: Weaning Food Stains on 12 Tray Materials

The material property that determines whether a highchair tray stains is porosity, not colour and not price. A non porous, non textured surface releases weaning food because nothing has penetrated it. A porous or heavily textured surface holds pigment in the grain or in the texture, and no amount of scrubbing after the fact will retrieve it.

We have not carried out controlled staining trials, and no stain scores, removal percentages or rankings are published in this report. What follows is our assessment of how the surfaces used on highchairs and feeding trays behave against the specific foods that dominate weaning in British households, and the design features that matter more than the material itself.

Key findings at a glance

• Porosity governs staining: a sealed, non porous surface will not hold pigment even from strongly coloured foods.
• Turmeric, tomato, carrot and beetroot are the pigments that cause almost all persistent highchair staining, and they behave differently from one another.
• Carotenoid pigments in carrot and sweet potato are fat soluble, which is why they cling to plastics and why washing up liquid removes them better than water alone.
• Texture matters as much as material: a matt textured plastic holds pigment in its surface relief where a gloss version of the same plastic does not.
• Time is the single biggest controllable variable; almost every weaning stain is removable if addressed before it dries.
• Tray joints, lip channels and strap slots trap more food than the tray face and are the real hygiene issue.
• A removable tray insert that fits a dishwasher solves more practical problems than any choice of surface material.

Why weaning food stains at all

Staining requires a pigment and somewhere for it to go. The pigments involved in weaning are a short list. Turmeric contains curcumin, an intensely coloured compound that is poorly soluble in water and readily soluble in fats and alcohols, which is why a turmeric mark shrugs off a wet cloth and lifts with soap. Tomato contains lycopene and carrot and sweet potato contain beta carotene, both carotenoids and both fat soluble, behaving in much the same way. Beetroot contains betalains, which are water soluble but extremely strongly coloured and quick to bind.

Where the pigment goes depends on the surface. Unsealed timber has open grain that draws liquid in by capillary action, so a beetroot spill on bare wood is absorbed rather than deposited. Silicone is non porous but is a soft polymer that can absorb oils and the fat soluble pigments carried in them, which is why silicone bakeware and feeding mats discolour over time. Polypropylene is chemically resistant but, when moulded with a matt or textured finish, presents thousands of tiny recesses that hold pigment mechanically rather than chemically.

Understanding this reframes the question. The material that cleans best is not the toughest one. It is the one with the smoothest, least porous, least textured surface, and that is why glass, glazed ceramic, stainless steel and gloss finished laminates outperform materials that feel more premium in the hand.

What actually happens on a highchair tray

Highchair trays in the UK are built from a small set of surfaces: moulded polypropylene, ABS, acrylic, silicone, stainless steel, powder coated steel, sealed or lacquered timber, oiled timber, melamine faced board, and increasingly bamboo composite. The same chair often combines several, which is why one part of a highchair discolours while another does not.

Sealed timber is the most misunderstood. A wooden highchair with a lacquered tray behaves like a plastic one as long as the lacquer is intact. Once the lacquer is scratched, usually by a metal spoon or by abrasive cleaning, the timber underneath is exposed at the scratch line and pigment enters there. The result is a stain that follows the scratch. This is a coating failure rather than a timber failure, and it is why abrasive cream cleaners are the worst thing to use on a wooden highchair.

Silicone behaves in the opposite way to expectations. It is easy to wipe, flexible and dishwasher safe, but it is permeable to oils. Repeated exposure to carotenoid rich purees leaves a gradual orange cast that is cosmetic rather than hygienic. Sunlight exposure is the commonly used remedy, as ultraviolet light degrades the pigment in situ. Bamboo composite trays vary enormously depending on the binder and the surface coating, and should be judged on the coating rather than on the bamboo content. Where a highchair sits alongside other pieces in a family kitchen, the same cleanability logic applies to the seating in childrens table and chairs UK sets.

The design features that matter more than the material

In everyday use, the surface material is secondary to the geometry. Food does not accumulate on the flat centre of a tray, which gets wiped after every meal. It accumulates in the raised lip channel around the edge, in the joint between a removable tray insert and the tray beneath, around the crotch post, in the harness strap slots and in the gap between the seat pad and the seat shell.

A one piece moulded tray with a generous radius at every internal corner can be wiped clean in one pass. A tray with a square internal corner between the face and the lip requires a cloth pressed into the corner, and in practice that corner does not get cleaned daily. Two part trays with a removable insert are excellent provided the insert can be lifted out easily and the tray beneath is itself smooth; where the insert clips into a recessed rebate, that rebate becomes a food trap.

Fabric and foam seat pads are the other issue. A wipe clean coated seat pad is far more practical than a woven fabric pad, and a pad that unclips and goes in a washing machine is better than either. Harness straps should be removable for washing, because webbing absorbs milk and puree and is the part of a highchair most likely to develop an odour. None of this is visible in a product photograph, which is why it is worth checking before purchase, in the same way buyers examine construction across childrens chairs UK generally.

Surface behaviour against common weaning foods

The table below describes how each tray surface behaves in use, and the cleaning approach suited to it. It sets out material properties and recommended handling rather than measured stain removal results, since no controlled testing underpins this report.

What this means for UK homes

Clean before it dries. This is more effective than any material choice. A wet cloth immediately after a meal removes almost every weaning pigment from almost every surface, including textured plastic and lacquered timber. A dried turmeric mark on the same surface is a different problem entirely.

Use washing up liquid rather than water for orange and yellow foods. Curcumin, lycopene and beta carotene are fat soluble, and a surfactant lifts them where plain water simply spreads them. For beetroot, act fast with water, because betalains bind quickly and are less responsive to detergent once set.

Buy for geometry, not for finish. Look for a tray with rounded internal corners, a removable insert that lifts clear without a recessed rebate, a wipe clean or machine washable seat pad and harness straps that detach. Check whether the tray fits a dishwasher basket, because in practice that determines how thoroughly it gets cleaned. Finally, in a kitchen diner, plan the highchair’s position before buying: it needs around 60cm of clear width and space for an adult to sit alongside, which is easy to overlook when a dining set has been sized to the room. Households working within tight open plan layouts should factor this in when choosing from the modern dining table and chairs sets UK range, and consider whether a nearby childrens storage furniture UK unit can keep bibs and cloths within reach of the chair.

Methodology

This report was compiled in 2026 by the editorial team at Furniture in Fashion. It draws on our assessment as a UK furniture retailer and on the established physical and chemical properties of the surface materials described, including the solubility characteristics of the food pigments involved. We did not conduct controlled staining or cleaning trials, and no stain scores, removal rates, rankings or percentages are published here, because we hold no measured dataset and no published UK study compares these surfaces under matched conditions. The report does not use proprietary sales data, customer data or survey fieldwork, and no panel provider or academic partner was involved.

Parenting and interiors titles are welcome to cite this 2026 analysis with credit to Furniture in Fashion and a link to our site. It is an editorial assessment of material behaviour and highchair design rather than a laboratory cleaning test, and we ask that it is described in those terms.

Frequently asked questions

Why does turmeric stain a highchair tray so badly?

Curcumin, the pigment in turmeric, is intensely coloured and poorly soluble in water but readily soluble in fats and detergents. Wiping with plain water tends to spread it, while warm water with washing up liquid lifts it. On a textured surface it becomes trapped in the relief, which is why matt finishes hold it longer than gloss.

Can stained silicone be restored?

Discolouration in silicone comes from fat soluble pigments absorbed into the polymer, so scrubbing has little effect. Leaving the item in direct sunlight fades the pigment over time. The discolouration is cosmetic and does not indicate that the item is unhygienic.

Is a wooden highchair harder to keep clean?

Not if the finish is intact. A lacquered wooden tray behaves much like a plastic one. The problem begins when the lacquer is scratched, usually by a metal spoon or an abrasive cleaner, because pigment then enters the timber along the scratch. Avoid abrasive creams and dry the surface rather than letting water stand.

Which part of a highchair is hardest to clean?

Not the tray face. The lip channel around the tray edge, the joint beneath a removable insert, the harness strap slots and the gap between seat pad and shell collect far more food. Removable straps and a washable pad make more practical difference than the tray material.

Should a highchair tray go in the dishwasher?

Where the manufacturer states it is dishwasher safe, yes, and in practice this is the strongest predictor of whether a tray gets thoroughly cleaned. Bamboo composite and some coated timber trays should not be put in a dishwasher, as heat and prolonged wetting break down the coating and the binder.
