It sounds like you’re describing a traditional cleaning or home remedy tip. A common “Nana’s trick” that fits what you’ve started is using something like baking soda. It works because baking soda has mild abrasive properties, which means it can scrub away dirt and stains without being harsh enough to damage most surfaces.
That gentle abrasiveness helps lift grime, while its chemical nature also allows it to neutralize odors and break down certain types of residue. Combined with something acidic (like vinegar or lemon), it can even create a fizzing reaction that helps loosen stubborn buildup.
If you want, share the full trick you have in mind—I can break down exactly why each ingredient works.
