Ball Pool & Ball Pit hygiene: Why arent’t there cleaning regulations — and what operators must do

Ball pools and ball pits were not originally designed for mass use. They emerged in the 1970s alongside advances in plastics manufacturing, first appearing as tools for sensory and motor development therapy in controlled, small-group settings. From the 1980s onward, however, they rapidly spread into the entertainment industry and quickly became a defining feature of indoor playgrounds and soft play centres worldwide.

The environment in which these products are used changed radically – but ball pit hygiene regulations did not keep pace with that change.

Why Is There No Central (EU-Level or International) Cleaning Regulation?

In the case of ball pools and ball pits, the obstacle to the development of regulations does not lie in the absence of hygiene risks, but ratherthe absence of a clear legal classification. The core problem is that ball pools do not fit neatly into any single classic regulatory category, either legally or functionally.

1. Not a Medical Device

Ball pools are not qualified as medical or healthcare devices, therefore do not fall under the direct jurisdiction of international bodies such as the WHO or the ECDC. Even where they are used therapeutically – for example in developmental or rehabilitation settings – they are not licensed as healthcare equipment. As a result, no mandatory disinfection requirements or validated cleaning protocol applies to them.

2. Not a Food-Contact Surface

Ball pools are not subjected to food safety regulation either. They are not classified as food-contact surfaces, which means HACCP requirements and the mandatory cleaning and disinfection standards associated with them do not apply. Legally, they are considered so-called “passive surfaces,” for which no mandatory microbiological cleanliness standard is prescribed.

3. Not a Personal-Use Item

Although ball pool and ball pit balls are collectively used objects, they cannot be categorised as personal hygiene items. They are not designed for hand sanitization or regular individual cleaning, and given their scale and volume they cannot be washed all at using conventional methods. This particular pattern of use creates a legal grey zone, where the risks of communal use are not matched by mandatory hygiene requirements.

4. A Children’s Toy, but Not a Toy in the Classic Sense

Standards for children’s toys – such as EN 71 – are frequently cited as a reference point in discussions about ball pools. However, these standards focus primarily on material safety, mechanical compliance, and toxicological risk. They do not regulate cleanability, disinfectability, or the control of microbiological load, and they prescribe no mandatory hygiene levels.

As a result, there is currently no standard legal or technological category into which ball pools can be unambiguously placed. This explains why no unified, legally binding European or international cleaning regulation has emerged.

How Do Authorities Carry Out Inspections Then?

In the absence of a regulatory framework for ball pit and ball pool hygiene, authorities and professional bodies worldwide primarily issue recommendations. These are non-binding and serve as guidance for operators. In practice, they typically take the form of internal institutional protocols, ‘best practice’ documents, and adaptations of general surface disinfection and sanitization principles.

This is why almost every official formulation includes the statement that “the frequency and method of cleaning is the operator’s responsibility.”

This approach is not accidental – it is the product of deliberate legal self-protection. There is no universally accepted technology, no measurable standardised cleanliness threshold, and no verifiable procedure on which a binding requirement could be built. In the absence of these, responsibility falls to operators, who establish their cleaning and sanitization practices according to their own judgement and capabilities.

International Examples of Recommendations for cleaning  Ball Pools

Although there is no unified, binding international regulation on ball pool or ball pit cleaning, a number of countries and regions have produced official and professional guidance documents that specifically address the hygiene risks of indoor playgrounds and soft play centres. These documents illustrate how ball pits are treated in contexts where the issue has already received institutional attention.

United States – guidelines at the state and local levels

In the United States, instead of federal-level requirements there are  state and county guidance documents. New York, California, Texas, and Minnesota all articulate similar principles: documented cleaning protocols, traceability, and immediate action in the event of contamination – but none mandates a specific technology or cleaning interval.

New York State health guidance treats ball pits as high-risk toy elements. Characteristic principles include:

•ball pit balls must be regularly removed and disinfected,

•in the event of contamination, immediate removal and full cleaning is required,

•cleaning frequency must be adjusted to the level of use.

Inspections primarily assess whether the operator has a documented ball pit cleaning procedure in place.

In California, several counties provide guidance through internal inspection manuals. Expectations include a written cleaning protocol, a traceable cleaning frequency, and verifiable disinfection and sanitization. Texas and Minnesota follow a similar approach: regular full cleaning is prescribed, immediate action is expected in the event of visible contamination, but the specific methods are left to the operator.

United Kingdom – Professional Recommendations

The UK’s Health and Safety Executive (HSE) does not issue a specific regulation on ball pools, but it does emphasise the regular cleaning of communally used play equipment, the application of enhanced hygiene measures in the event of infection risk, and the operator’s clear responsibility. Several British local authorities specifically recommend mechanical cleaning of ball pools. This approach is reinforced by infection control guidance documents for soft play facilities and by the practical recommendations of RoSPA.

Australia – More Specific Recommendations

The guidance issued by the New South Wales health authority is among the most specific documents available. It includes the need for regular disinfection of ball pools, recommends weekly or more frequent cleaning for high-traffic facilities, and advises immediate removal and cleaning in the event of contamination. These provisions are nonetheless not legally binding; they serve as professional guidance.

Summary – What is the  International Practice?

Based on the examples reviewed, a clear pattern emerges:

•ball pools and ball pits are everywhere treated as a distinct risk category,

•the need for regular cleaning and sanitization appears in all contexts,

•there is no universally prescribed technology or precise cleaning frequency,

•hygiene responsibility is consistently placed on operators.

Based on the above, it can be stated with professional confidence that while recommendations on ball pool and ball pit cleaning exist worldwide, they are typically non-binding and do not specify a uniform method or frequency.

The level of hygiene safety therefore depends decisively on the cleaning technology applied and the quality of the practices established by the operator. This situation means that operators must take full responsibility not only for carrying out cleaning, but also for its adequacy and verifiability.

Based on current international practice, it can be stated that ball pool and ball pit hygiene safety is not primarily a regulatory question, but above all, a matter of technology and operational practice.

What Can Operators Do?

The regulatory gap does not mean operators have nothing to act on – quite the opposite. Since responsibility rests entirely with the operator, the choice of cleaning solution becomes a strategic decision. Operators who rely on ad-hoc manual cleaning face growing exposure: no documented procedure, no verifiable frequency, no defensible standard.

The Pure-Matic ball cleaning machine offers a proven, machine-based approach: individually washed balls, documented cycles, and independently tested results – reducing bacteria by up to 95%. It is the kind of solution that satisfies what inspectors, parents increasingly expect from a responsibly run soft play or indoor playground.
