There are a few things to keep in mind when searching for the best marble cleaner.
Low ph cleaner for marble.
Alkaline based cleaning solutions for marble work the best.
Acidic cleaners with a low ph like vinegar ph 3 hydrogen peroxide ph 4 or citrus lemon orange ph 2 4 etch marble.
Any cleaner with ph above 10 etches marble which is why bleach ph 12 and ammonia ph 11 are not for cleaning marble.
Therefore safe cleaners will say marble cleaner safe for use on marble or maybe ph balanced these cleaners are designed for marble and should be safe for use.
Because marble is porous and not as hard as some other natural stones like granite acid based cleaning products will damage marble and will likely produce headaches rather than results.
Alkaline marble cleaners are okay up to a point.
Toilet bowl cleaner is another acidic cleaner that helps break down and remove mineral and other non organic substances.
However there are some acids with a higher ph those are stronger then acids with a lower ph.
Ammonia has a ph or roughly 11 5 12 therefore a safe marble cleaner needs to be below a ph of 11 5.
On the alkali side the higher the ph number the stronger the alkali should be.
After this research we determined that for a marble cleaner to be safe it s ph levels need to be between 7 11 5.
Because of its acidic level caution and ventilation will be needed.
To be extra careful read the backside of the cleaner and see if it offers the ph level of the cleaner.
