Barbicide Disinfectant Concentrate Professional-Grade Sterilization for Barbers & Salons 1.89L/63.91oz

The blue jar on the barber's counter is Barbicide, and it has been the visible sign that a shop takes hygiene seriously for decades. This is the concentrate that fills it.

Mixed with water at the dilution on the label, it becomes the solution combs, shears, clipper attachments and nail tools sit in between clients. The formula is non-corrosive, which is the practical reason professionals use it rather than something harsher: it will not pit metal shears, cloud plastic handles or blunt an edge over months of soaking.

1.89 litres of concentrate goes a long way once diluted, so the large bottle is the sensible buy for a working shop rather than the extravagant one.

Follow the dilution ratio and the contact time printed on the bottle. Both matter. Tools also need cleaning of hair and product before they go in, because the solution works on a clean surface and not through a layer of grease.

Keep the jar covered between uses and change the solution on whatever schedule your local rules set, rather than waiting until it looks tired. It stays blue long after it has stopped doing much, so colour is a poor guide to whether it is still working.
