Granite countertop care and maintenance comes down to just a few simple steps that will keep your granite countertops looking like new for years. Polished granite will not lose its shine and will not scratch from normal wear.
The easiest way to clean granite countertops is to simply use warm water and a mild, phosphate-free, biodegradable liquid dish soap, preferably light-colored and containing no aromatics. This is a gentle way to clean the grease and grime from your granite counters without damaging them. If you use plain soap and water, this can lead to soap build up and over time, will dull the glossy finish of your polished granite. You can also buy special mild granite cleaners specifically designed for cleaning stone.
To avoid damaging granite, never use powdered cleaners as they contain pumice which is abrasive, and never use acidic cleaners that may include ammonia when cleaning granite countertops.
