I hate cleaning so it’s always handy to have tools that actually help the job you need to do. My oven and stove aren’t too bad as I generally clean as I go, but these little tools work pretty well to help clean around the stove top when needed. I have yet to tackle my oven …. but I’m very good at procrastination when it comes to that task. I might use these on my cast iron camping pans, but I wouldn’t use these on my good stainless cookware as I think they would scratch. I don’t know how long they will last but they do feel reasonably well made. They are certainly useful for getting into some of the smaller nooks and crannies without breaking your finger nails! So far, these little tools have proven to be very useful.
