Stains caused by etching\u2014also known as hydrochloric acid\u2014are one of those problems that can appear when you least expect it, and are as delicate as they are difficult to solve. Although it's a product often used for cleaning, the truth is that it's very aggressive and can leave permanent damage to various types of flooring if not handled carefully. Therefore, knowing how to remove etching stains from your floor isn't just useful: it can mean the difference between a floor that's permanently damaged and one that looks like new again.<\/p>\n\n\n\n
Etching chemically affects the minerals present in many floors, especially those containing calcium carbonate, such as marble, terrazzo, or limestone. The result? Whitish, opaque, sometimes rough stains that can't be removed with a mop or ordinary cleaning products. And on ceramic or porcelain floors, it can damage the enamel, leaving dull areas.<\/p>\n\n\n\n
Understanding this reaction helps you anticipate and, above all, act wisely when it comes to correcting the damage.<\/p>\n\n\n\n
Not all pavements react the same to acid. In fact, there are very marked differences, and this greatly influences the treatment. So the first thing to know is what you're dealing with:<\/p>\n\n\n\n
This information will help you avoid making mistakes that could make the problem worse.<\/p>\n\n\n\n
When the etching comes into contact with the marble, what happens is called etching<\/em>, a kind of "etching" on the surface. You'll notice it because that area looks matte, with a whitish hue.<\/p>\n\n\n\n Here, more than a cleaning, what is needed is a recovery of the surface.<\/p>\n\n\n\n Terrazzo combines marble and cement, so the action of the acid is doubly aggressive.<\/p>\n\n\n\n These floors are more durable, but that doesn't mean they're invulnerable. Etching can dull the glaze or leave the surface uneven.<\/p>\n\n\n\n This type of pavement is porous, and the acid opens those pores and leaves whitish stains.<\/p>\n\n\n\n Here, more than cleaning, it's about giving the floor back its finishing coat.<\/p>\n\n\n\n This product is not a toy. If you're going to use it, or if you need to treat an affected area, please take these steps:<\/p>\n\n\n\n There are times when home remedies aren't enough, and forcing the situation can make things worse.
