The old tried and true Baking Soda treatment. Sprinkle a lot of it on the spot, leave a day or two, and wash off with water. If you still have an issue, sprinkle with a fine layer of cat litter.

Awesome, thanks! I’ll try when it stops snowing.

Has a scrub brush been used? Are all little bits gone? I cannot imagine why the smell would still survive if there wasn’t still residue somewhere.

@Pied_Pfeffer I’ve used an old sponge but not a cleaning brush. It’s not my porch and was hoping for an easy answer. I’ll try that if the baking soda doesn’t work.

Baking soda and hydrogen peroxide together might bubble the stink out. I know exactly what you mean too. I forgot about a box of apples in my basement one year. Ugh.
The kitty litter is an excellent suggestion too @YARNLADY. Clay type works better than scoopable for absorbing.

Two suggestions: Try not just soaking in baking soda, but scour it with a paste of baking soda and water. Failing that, rinse that all off and try soaking in vinegar. It’s a great deodorizer.

@Likeradar just curious, but if it’s snowing where you live, doesn’t the snow block out the scent? Is it really that powerful?

@Carly The snow’s not accumulating, just making everything wet. And yes, it’s STRONG.

Something is amiss then. There must be a rotting pumpkin (or something) around. See how far you can walk before you can’t smell it. It should help you zone in on the source.

Use Orange oil!!!
I just used some to clean some sticky, smelly nastiness off the floor of my dorm kitchen. It works wonders and it smells amazing!

Poor you. They smell bad enough when fresh…
