Very happy with my purchase. The spray bottle is good quality and the Koh multi purpose cleaner got my ovens clean without leaving a lingering smell or toxic fumes like other products I’ve used. The diamond scrubbers worked well to remove the grime after leaving the cleaner time to dissolve the tougher to remove stains and marks. I have yet to use the product for other applications but I am impressed with the way it worked on my ovens and I would recommend Koh to anyone looking for an effective but environmental friendly product.
