Grandma's Secret Spot Remover seems to have a reputation for tackling a bunch of tough stains, including grease. It's made without harsh stuff like chlorine and bleach, which means it's safe for delicate fabrics.
According to the manufacturer, it can deal with tricky stains like oil, blood, pet accidents, and paint. From what we've found, folks often have good luck using it on grease stains as long as they treat them quickly. A lot of people say it works best when you apply it directly on the stain, give it some time to soak in, and then toss the fabric in the wash. Fresh stains are definitely where it shines, which fits with the usual advice for grease.
The reviews aren't all sunshine and rainbows, which is kind of expected since different fabrics and stain types respond differently. Some users say that really old or set-in stains might need a few tries before they fully disappear. This lines up with broader research, too—it's effective, but sometimes needs a bit of persistence with tough, older stains.
So, if you're thinking about using this for grease stains, it's probably best to jump on the stain as soon as it happens and follow up with a regular wash. This seems to match what a lot of happy users mention.
Just keep in mind, while it's not a one-size-fits-all miracle worker, Grandma's Secret Spot Remover could definitely be handy for those stubborn grease spots. Plus, don't forget to test it on a hidden part of the fabric first to make sure there's no unwanted fading or damage.
All in all, if you're in the market for a stain remover that's gentle yet effective, it could be worth giving it a try, though you might need a little patience with tougher stains.
