Nuncas Marine Teak Brightener is the unique solution for removing the grey patina that forms over time on teak floors, finishing touches and furniture. The action of the sun and weather can be extremely aggressive. This cleaner is formulated only with naturally occurring acids that remove the signs of ageing from teak and restore its original natural colour, without damaging the structure of the wood itself. This step prepares the wood for possible subsequent treatment with Nuncas Marine Teak Oil.
