A closed stone carpet is best cleaned with a vacuum cleaner.

Occasionally clean the stone carpet with water and ‘soap without soap’, with a neutral pH value, or sometimes use slightly acid pH 5-6 to dissolve any remaining lime residue of the mains water.

It is important to suck up or mop up as much water as possible every time you have cleaned the floor with water!

Solvents will surely affect the sealing material, causing it to become sticky.
