How do marble outdoor flower pots handle exposure to hard water?

Marble outdoor flower pots add elegance to gardens but can be affected by hard water. Hard water contains minerals like calcium and magnesium, which may leave white stains or residue on marble surfaces over time. To minimize damage, regularly wipe pots with a soft cloth and distilled water. Avoid harsh cleaners, as they can etch the marble. Applying a sealant can also help protect the surface. With proper care, marble pots can withstand hard water while maintaining their luxurious appearance.
