Ultramar Sail Number Remover has been used by Ultramar Sail & Tent Cleaners since 1998 for safely removing old adhesive remains from sail cloth, tent cloth and boat cloth. New signs can be applied as soon as the cloth is dry.
If necessary, spay and brush the adhesive remains a couple of times.
CAUTION! Do not inhale the spray. Only use in well-ventilated locations. Read the instructions on the packaging before use.
Usage depends on the thickness of the layer of adhesive.
