Aims  Dry surface biofilms (DSB) survive on environmental surfaces throughout hospitals, able to resist cleaning and disinfection interventions. This study aimed to produce a dual species DSB and explore the ability of commercially available wipe products to eliminate pathogens within a dual species DSB and prevent their transfer.    Methods and Results   Staphylococcus aureus  was grown with two different species of  Bacillus  on stainless steel discs, over 12 days using sequential hydration and dehydration phases. A modified version of ASTM 2967–15 was used to test six wipe products including one water control with the Fitaflex Wiperator.  Staphylococcus aureus  growth was inhibited when combined with  Bacillus subtilis . Recovery of  S. aureus  on agar from a dual DSB was not always consistent. Our results did not provide evidence that  Bacillus licheniformis  protected  S. aureus  from wipe action. There was no significant difference of  S. aureus  elimination by antimicrobial wipes between single and dual species DSB.  B. licheniformis  was easily transferred by the wipe itself and to new surfaces both in a single and dual species DSB, whilst several wipe products inhibited the transfer of  S. aureus  from wipe. However,  S. aureus  direct transfer to new surfaces was not inhibited post‐wiping.    Conclusions  Although we observed that the dual DSB did not confer protection of  S. aureus , we demonstrated that environmental species can persist on surfaces after disinfection treatment. Industries should test DSB against future products and hospitals should consider carefully the products they choose.    Significance and Impact of the Study  To our knowledge, this is the first study reporting on the production of a dual species DSB. Multispecies DSB have been identified throughout the world on hospital surfaces, but many studies focus on single species biofilms. This study has shown that DSB behave differently to hydrated biofilms.
