Seems like an easy enough question right? Well not really. The term \u201cstain\u201d is used very often, but the problem the customer is facing may not be an actual \u201cstain.\u201d<\/p>\n<p>&nbsp;<\/p>\n<p>Let\u2019s define what a stain is. A stain is a discoloration of the stone; however, the surface finish of the stone remains smooth.<\/p>\n<p>The most common types of stains are:<\/p>\n<ol>\n<li>Oil-based (oils and grease)<\/li>\n<li>Organic (such as coffee or fruit)<\/li>\n<li>Metal (such as rust)<\/li>\n<li>Biological (algae, mildew or mold)<\/li>\n<li>Ink<\/li>\n<li>Paint<\/li>\n<\/ol>\n<p>&nbsp;<\/p>\n<p>Not to be confused with an etch mark. An etch mark is a chemical burn that forms when acid, ammonia, or alcohol comes into contact with the calcium carbonate element that exists in certain natural stones. These marks look like the finish or the shine has been removed from the surface of the stone. The area that is etched typically feels a little rough to the touch. Etch marks are most common on marble, travertine, limestone, and terrazzo surfaces.<\/p>\n<figure id=\"attachment_316\" aria-describedby=\"caption-attachment-316\" style=\"width: 225px\" class=\"wp-caption alignleft\"><a href=\"http:\/\/intlstoneworks.com\/blog\/wp-content\/uploads\/2014\/06\/Wax-stain.jpg\"><img loading=\"lazy\" class=\"size-medium wp-image-316 \" alt=\"Wax stain\" src=\"http:\/\/intlstoneworks.com\/blog\/wp-content\/uploads\/2014\/06\/Wax-stain-225x300.jpg\" width=\"225\" height=\"300\" srcset=\"http:\/\/intlstoneworks.com\/blog\/wp-content\/uploads\/2014\/06\/Wax-stain-225x300.jpg 225w, http:\/\/intlstoneworks.com\/blog\/wp-content\/uploads\/2014\/06\/Wax-stain.jpg 480w\" sizes=\"(max-width: 225px) 100vw, 225px\" \/><\/a><figcaption id=\"caption-attachment-316\" class=\"wp-caption-text\">Oil-Based Stain<\/figcaption><\/figure>\n<figure id=\"attachment_92\" aria-describedby=\"caption-attachment-92\" style=\"width: 300px\" class=\"wp-caption alignright\"><a href=\"http:\/\/intlstoneworks.com\/blog\/wp-content\/uploads\/2013\/09\/photo-380-e1386877352768.jpg\"><img loading=\"lazy\" class=\"size-medium wp-image-92 \" alt=\"photo-380\" src=\"http:\/\/intlstoneworks.com\/blog\/wp-content\/uploads\/2013\/09\/photo-380-e1386877352768-300x280.jpg\" width=\"300\" height=\"280\" srcset=\"http:\/\/intlstoneworks.com\/blog\/wp-content\/uploads\/2013\/09\/photo-380-e1386877352768-300x280.jpg 300w, http:\/\/intlstoneworks.com\/blog\/wp-content\/uploads\/2013\/09\/photo-380-e1386877352768.jpg 472w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><figcaption id=\"caption-attachment-92\" class=\"wp-caption-text\">Acid Etch Mark<\/figcaption><\/figure>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>So now the most important question, how do you remove stains and etch marks?<\/p>\n<p><span style=\"text-decoration: underline;\">Treating Stains<\/span><\/p>\n<p>Knowing the type of stain will help identify which stain removal technique is needed. However please keep in mind that when stains are very deep, they may not be able to be removed.<\/p>\n<p>&nbsp;<\/p>\n<p>To help prevent oil and organic stains, we recommend sealing your stone with <a title=\"SG S\" href=\"http:\/\/www.intlstoneworks.com\/sealers\/sealnngo_s.htm\">Seal &amp; Go\u00ae S<\/a> or <a title=\"SG W\" href=\"http:\/\/www.intlstoneworks.com\/sealers\/sealnngo_w.htm\">Seal &amp; Go\u00ae W<\/a>. These sealers are penetrating sealers, meaning they go into the pores of the stone and repel non-acid liquids like water, coffee, tea, grease, oil, etc. We recommend re-sealing your stone annually especially in kitchens and bathrooms. You may need to apply more than one application of the sealer.<\/p>\n<p>If you want to learn more about how to apply Seal &amp; Go\u00ae S or Seal &amp; Go\u00ae W, check out our blog post, <a title=\"Smooth Sealing\" href=\"http:\/\/intlstoneworks.com\/blog\/2013\/05\/08\/smooth-sealing-2\/\">\u201cSmooth Sealing.\u201d<\/a><\/p>\n<figure id=\"attachment_197\" aria-describedby=\"caption-attachment-197\" style=\"width: 225px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/intlstoneworks.com\/blog\/wp-content\/uploads\/2013\/12\/for-blog.jpg\"><img loading=\"lazy\" class=\"size-medium wp-image-197 \" alt=\"for blog\" src=\"http:\/\/intlstoneworks.com\/blog\/wp-content\/uploads\/2013\/12\/for-blog-225x300.jpg\" width=\"225\" height=\"300\" srcset=\"http:\/\/intlstoneworks.com\/blog\/wp-content\/uploads\/2013\/12\/for-blog-225x300.jpg 225w, http:\/\/intlstoneworks.com\/blog\/wp-content\/uploads\/2013\/12\/for-blog.jpg 480w\" sizes=\"(max-width: 225px) 100vw, 225px\" \/><\/a><figcaption id=\"caption-attachment-197\" class=\"wp-caption-text\">Sealing with Seal &amp; Go\u00ae S<span class=\"Apple-style-span\" style=\"font-size: 15px; line-height: 21px;\">\u00a0<\/span><\/figcaption><\/figure>\n<p>&nbsp;<\/p>\n<p>If you have a surface stain on your stone, you can apply a poultice on the stain.\u00a0Per the <a title=\"MIA\" href=\"http:\/\/www.marble-institute.com\/\">Marble Institute of America<\/a>, a poultice is \u201ca liquid cleaner or chemical mixed with white absorbent material to form a thick, stain removing paste.&#8221; Some poultice options you have are <a title=\"Oil &amp; Grease Remover\" href=\"http:\/\/www.intlstoneworks.com\/residential\/akemi_oilgrease_remover_paste.htm\">Akemi Oil &amp; Grease Remover Paste<\/a>, <a title=\"Mangia Macchia\" href=\"http:\/\/www.intlstoneworks.com\/residential\/bellinzoni_il_mangia_macchia.htm\">Bellinzoni Mangia Macchia<\/a>, or <a title=\"SAC\" href=\"http:\/\/www.intlstoneworks.com\/specialty\/sac.htm\">SAC<\/a> (Stain Absorbing Compound).<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"text-decoration: underline;\">Treating Etch Marks<\/span><\/p>\n<p>Unfortunately, simple cleaning won\u2019t remove etch marks.
