Raku No-Etch
Raku No-Etch is a treatment for marble, travertine, and limestone that reduces how easily the stone etches from acidic spills like lemon juice, wine, tomato sauce, and vinegar-based cleaners. Etching isn't a stain sitting on the surface, it's the acid actually eating into the stone, which is why a normal seal or cleaning can't fix it once it happens.
This treatment doesn't make stone etch-proof. Softer stones like marble and limestone will always be more vulnerable to acid than something like granite. What it does is slow down how fast and how visibly acid contact affects the surface, buying more time before a spill turns into a permanent dull spot. It's most often requested for kitchen countertops and other surfaces that regularly come into contact with food and drink.
FAQ
- Does Raku No-Etch make my countertops etch-proof?
- No treatment makes marble or limestone fully etch-proof. This treatment reduces how quickly and visibly acid affects the surface, but spills should still be wiped up right away.
- Is this the same as sealing?
- No. Sealing protects against staining from liquids soaking in. This treatment specifically targets etching, which is surface damage from acid, not staining.
- Which stones benefit most from this treatment?
- Softer, more porous stones like marble, travertine, and limestone benefit the most, since they're the most prone to etching. Denser stones like granite are naturally more resistant already.
- How long does the treatment last?
- It should be checked and reapplied on the same schedule as your regular sealing, since both treatments protect the same surface pores.
