International Stain Remover
PRICE: £12.30/500ml (£24.60/lt)
International Stain Remover is part of a new range of cleaning products. The instructions say that it is to be applied generously with a brush or sponge in small circular motions, left on the surface for 10 minutes
and washed off. Application was simple, as described. Upon cleaning off, some light staining remained, requiring a second application in order to shift the more stubborn stains.
