Because they are made of eco-friendly materials, ONNO disinfection barriers require minimal maintenance by the user.
Occasionally wiping the barrier surfaces with a soft cloth and a mild inox cleaner is the only obligation.
The disinfectant liquid in the footwear disinfection tub is replenished easily and quickly, by opening the faucet at the bottom of the right inner side of the barrier, under the small lid. The tub should be washed with clean water if necessary.
Everything else, filling the tank with disinfectant liquid, maintenance according to the condition and servicing in the warranty and out-of-warranty period, is the concern of the ONNO service team.
