You can do that. But you have to make sure to clean CAREFULLY with Wood Cleaner and wash with clean water to make sure that the surface is no longer basic and with that damage the lacquer.
WOCA Spot Remover is perfect for indoor use to remove spots.
If necessary, repeat the treatment till the spot is gone. Always remember to finish with WOCA Natural Soap, WOCA Maintenance Oil or WOCA Maintenance Paste.
