Our panini grill was very gunked up. This worked well to clean it. Had to use twice and really scrub but now we use this product regularly and it cleans easily and efficiently.

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.

I read in a comment on chafing trays that this works to clean stainless steel. I used it in our sinks and it certainly does remove residue and grease very quickly and easily with little to no scrubbing.

This is a really good degreaser for regular cleaning. If you have a lot of caked on grease you will need something stronger at first then this would be good after.

Awesome oven cleaner! My second favorite use is to put some on the flat top when it is still warm or hot and it will quickly eat away at anything baked on to your grill.

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.

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.

Used this to clean ovens and it works great. I would say there are cheaper solutions out there but this does a great job of getting stuck on grease without having to heat up the ovens.
