01 The verdict
No. Lemon juice damages marble.
- Never Citric acid etches marble, limestone and travertine within minutes.
02 Why: the two sides
Marble
Marble is porous stone, so spills can soak in and stains have to be drawn back out.
Marble, limestone and travertine are calcium carbonate, which acids dissolve: that is etching.
It is porous, so time matters: the longer a spill sits, the deeper it goes.
Lemon juice
Fresh or bottled lemon juice: citric acid plus sugar and colour. Pure citric acid powder does the same job without the sugar. pH 2–2.6.
With sunlight it bleaches; keep it off coloured fabric.
03 Use instead
Follow the stain file for the specific stain on marble; each one picks the safe product for that combination.

06 More about lemon juice
Acids dissolve minerals (limescale, rust, aluminium salts) and neutralise alkaline residues. They also dissolve calcium carbonate, which is why they etch marble and erode grout.
On an ingredient list, lemon juice shows up as citric acid.
- With sunlight it bleaches; keep it off coloured fabric.
Never mix it with chlorine bleach. Why.
07 Already used it?
If acid has already touched it, look for a dull, rough patch: that is an etch. Rinse with water, dry, and use a marble polishing powder for a small etch, or a stone restorer for anything larger.
08 Questions
Is diluted lemon juice safe on marble?
No. Dilution slows the damage but does not change what lemon juice does to marble: citric acid etches marble, limestone and travertine within minutes.
What should I use on marble instead of lemon juice?
Use the method in the stain file for the specific stain: on marble the right product depends more on the stain than on habit.
Can I mix lemon juice with other cleaners on marble?
Do not combine cleaners unless the exact product manufacturers explicitly direct that use. This ingredient-level file cannot establish compatibility of commercial formulas. Rinsing alone does not prove that later use of a different cleaner is safe, especially on porous materials.
Does lemon juice remove stains from marble?
None of the 31 files for marble uses it. Absence from the model does not establish either effectiveness or safety.
How long can lemon juice stay on marble?
Do not use it as a routine home treatment on this material. For accidental contact, follow the product and item instructions and obtain advice if needed.
