pH Neutral Cleaners

When cleaning natural stone surfaces such as granite, marble and travertine, it is important to know that daily cleaners should be "pH neutral". A neutral cleaner insures that the solution is neither low on the pH scale (acidic) or high on the pH scale (alkaline: bleach, ammonia). It is important to understand that many types of stone such as marble and travertine, contain calcite. If calcite comes in contact with a solution that is either high or low on the pH scale, the solution will gradually start to break down the stone causing polished and honed surfaces to dull or etch.
