It cleaned my filter but I will give it another cleaning.

Worked great, sprayed filter all down, let it soak and drain, the repeated about 3 more times, sprayed down with cold water to clear out the rest of the debris, let dry overnight. Engine is running much more smoothly.

The price is good for this item, and it works as advertised. I just wish you could buy a smaller bottle; this size will last me forever.
