Cleaning companies are calling for designated key worker status.
Companies are being hired to clean not only offices that remain open but also hospitals and schools that are taking care of the children of key workers.
Helen Williams, the founder and director of Clean Sweep, said cleaners are providing an important service to combat the coronavirus and should be officially classed as key workers.
Clean Sweep is preparing a ward at Singleton Hospital to be opened. Ms Williams' team also clean a warehouse that provides masks for the NHS, and clean schools.
But Ms Williams says her staff are also facing issues with childcare. Without the 'key worker' classification, her employees are having to rely on friends and family.
And Rayner Davies, of A&R Cleaning Services, says two of her staff were stopped on the way to clean a school that is open for the children of key workers.
"If cleaners were not providing their services in hospitals, schools and care homes, these industries would not be able to remain open," Mrs Davies added.
"Our cleaners are working on the frontline and are at risk. They go into areas where the coronavirus has been confirmned and do deep cleans."

Mrs Davies says that it's important the schools looking after children of key workers are kept as safe and clean as possible to prevent them bringing the virus home.
A Welsh Government spokesperson said: “If someone’s work is critical to the Covid-19 response and they work in one of the critical sectors listed in the published guidance, they should make arrangements for their child to be safely cared for at home. If there is no safe alternative, provision should be made in schools or other settings.
"The guidance includes ‘support and specialist staff’ in health and public services, and it is within the interpretation of this guidance that cleaning staff are providing an essential support service as part of the response and are considered key workers."
As the pandemic continues, many of those work places that remain open are turning to specially trained cleaning firms to keep their environment as safe and clean as possible.
Ms Williams said: “The outbreak of the coronavirus, naturally, has people worried. However, a deep clean by a trained company can decontaminate an office.”
Ms Williams explains her South Wales-based company uses an environmentally-friendly disinfectant that will eliminate coronavirus (SARS-associated), as well as human coronavirus (VR-740), canine coronavirus (VR-809), RNA and DNA, which is important when sanitising and decontaminating viruses.

“We use only the best tried and tested quality cleaning systems - including specialised disinfectants, equipment and procedures – to carry out environmental cleans," she said. "As these are persistent solutions, they will continue to be effective when they have dried, unlike alternative chemicals that are only effective when wet.
“These persistent, proactive solutions start to work within 10 seconds and continue to be effective against a plethora of viral and bacterial threats and pathogens.”
For sensitive places, such as clean rooms, research and development laboratories, healthcare facilities and schools, Ms Williams explains there is a more effective method for stripping dirt, dust and germs from surfaces that require specialised sanitation: electrostatic spray.
“Electrostatic spray surface cleaning is the process of spraying an electrostatically-charged mist onto surfaces and objects,” she said.
“It uses a specialised solution that is combined with air and atomised by an electrode inside the sprayer. Subsequently, the spray contains positively-charged particles that are able to aggressively adhere to surfaces and objects. Because the particles in the spray are positively charged, they cling to and coat any surface they’re aimed at."
