If it is still sticky, you can dissolve it with white spirit and a green polish pad. Wet a cloth with white spirit and wipe it over the floor (only a small area at a time). Then you polish with green pad with the machine till the sticky oil is removed.
If it is a large area or even just a small area, for instance a table, you can start removing most of it with a scraper. Alternatively, you can let it dry completely (it takes a least one week) and then scratch it off (you can also start with the scraper). Now, you have to apply Maintenance Oil or Wood Floor Oil again, remember to wipe off the excess oil after 15-20 minutes.
All the used raw materials in the Worktop Oil are FDA approved in the state of saturation.
All raw materials are harmless in the dried film and are only allergenic by direct contact and continuously use (for instance 8 hours a day for several years). If you use regular plastic/rubber gloves when you apply the oil, there is no risk at all.
