Does marble sealer prevent etching?
Most standard sealers only slow down staining, not etching, and fade within months. Opal Luxury is different — it bonds permanently to the stone and forms a real barrier against the acids that cause etching.
How can I protect marble countertops from lemon and vinegar?
Wiping up spills quickly helps, but it doesn't fully prevent etching from acidic foods like lemon, vinegar, wine or tomato sauce. A permanent, acid-resistant seal like Opal Luxury is the only protection that holds up to daily kitchen use.
Marble etching vs. staining — what's the difference?
Etching is a dull or discolored mark left by acid reacting with the stone's surface — it changes the finish, not just the color. Staining is a substance absorbing into the pores of the stone. Etching needs polishing to fix; staining needs poulticing. We assess before recommending protection.
Is Opal Luxury the same as a regular marble sealer?
No. Regular sealers sit on top of the stone and need reapplying every year. Opal Luxury bonds permanently to the stone itself and is applied once.
