"We have used your laundry powder for several years and have been delighted with its effectiveness. Did you also know that it is absolutely fabulous at removing built up fat from the side of your cooker you cannot quiet reach to clean. A preliminary wipe over with the laundry powder in about 50 deg C water primes it for the next wipe over that removes most of the build up. The remaining spots do not require too much elbow grease to remove. I also soak the grille from the kitchen fan in the solution and it just lifts the accumulated dust and fat, needing a rinse only. Have you considered this use in commercial kitchens to get away from using corrosive caustic soda?"
