Speaking from Australia
Where possible we use toothbrush and toothpaste TDS with peppermint water in between Q2h.
Other facilities use products ranging from sodium bicarb through to chlorhexidine mouthwash. Used as swabs Q2h - Q3h depending on the facility.
We USED to use a product made up by our state pharmacy called Thymol - it was a thyme based solution (thyme has natural antiseptic properties) but we are no longer using it - somone muttered something about "cruel and unusual punishment"?
Anyway could you also post any websites you have found so we may share information??
