    cleaner great cleaning price ovens degreaser grease grill hood job

    Great price and great product. Love this product for cleaning the kitchen and bar; we even put it in our mop water from time to time and it will strip the floor clean of grease and dirt.

    This oven cleaner was recommended as an alternative to a more expensive product. It works just as well, and is a great value for the money.

    Great product! This has been a lifesaver in cleaning years of grime off of our used oven and it's water based formula is much appreciated.

    I used this grill and oven cleaner today to clean my hood vents and hood. I put my hood vents in the dish machine and ran it on delimer cycle. Cleaned them up really well!

    Its a good product but not strong enough for tuff grease. Its a mild degreaser. Over all for the price its a fare degreaser for a kitchen.

    Unfortunately, we did not have great success with 1 Gallon Noble Chemical Knockout Liquid Heavy Duty Oven & Grill Degreaser & Carbon Remover, #999KNOCKOUT, product. It does not appear to work as well as our previous product.

    This is a pretty good cleaner for the price, gets the job done with minimal elbow labor and doesn't leave any after cleaning residue behind like other cleaners.
