Genuine low-porosity marble such as Makrana does not yellow by itself. Yellowing is almost always caused by something applied to it or by stone quality.
The usual causes
Acidic cleaners. Lemon, vinegar and harsh bathroom cleaners etch and stain marble.
Oils left to sit. Oil used during abhishek can oxidise and darken the surface if not wiped off.
Hard water. Mineral deposits build up as a dull, yellowish film.
Soft or composite stone. Porous or resin-bound materials discolour far more readily than Makrana.
Prevention
Wipe oil and water off after worship with a soft dry cloth. Use plain water for routine cleaning and reserve a pH-neutral stone cleaner for occasional deeper cleaning. In hard-water areas, dry the murti after washing rather than letting it air dry.
Fixing existing discolouration
Light mineral film usually lifts with a pH-neutral cleaner and a soft cloth. Deeper etching needs professional repolishing, which removes a very thin surface layer and restores the original whiteness. Ask before attempting abrasives — sanding a murti by hand almost always makes it worse.
Prevention is cheaper than repair
Two habits — dry after washing, never use acid — prevent the vast majority of discolouration complaints.
Frequently asked questions
Will a white marble murti stay white?
Genuine Makrana marble stays white with basic care. Yellowing is usually caused by acidic cleaners, oils left on the surface, or hard-water deposits.
Can yellowed marble be restored?
Light deposits lift with a pH-neutral cleaner. Deeper discolouration needs professional repolishing to remove the stained surface layer.
Is vinegar safe for cleaning marble?
No. Vinegar is acidic and will etch and dull marble over time. Use plain water or a pH-neutral stone cleaner.
