I got a few pickle buckets from McDonald's (for a small fee), and even after several bleach baths, they still smell like pickles. I've added a small air freshener to the Bucket Boss lid bottom, so when I open it, I don't get a strong wiff of pickles. I can only imagine what the containers that held the french fry grease would clean up like.
Maybe my nose is too sensitive (don't think so), but the clean bucket is the way to go.
That pretty much sums it up. Better than trying to clean grease out of the ones you stole from the back of Kentucky Fried Chicken.
It's worth the $5.
