As with our Swarfega winner, B&Q’s offering completely lifted our fresh oil test stain, even though the mixture consists predominantly of water when it is prepared to the suggested 1:20 dilution. Results on ingrained oil were less successful, however. While the sticky, black gloss was removed, the stain beneath wasn’t really touched. Still, this product is more user friendly than most, and it can be poured into a pressure washer. Rinsing away was pretty effortless, sealing the B&Q’s position as our Recommended buy.
