Using Mr. Clean Magic Eraser on Travertine Floors:
From time to time I receive some very good questions from people wanting specific help. Recently I was asked about using a Mr. Clean Magic Eraser on Travertine floors. Because this product is widely sold and is used on many surface types this is a great question. Before I answer the question let's first discuss what a Mr. Clean Magic Eraser is.
A Mr. Clean Magic Eraser is Melamine Foam and this foam like material consists of formaldehyde-melamine-sodium bisulfite copolymer. The foam is manufactured in Germany by BASF under the name "Basotect" with pH level of 8.0 -10.0. It has been used extensively as insulation for pipes and ductwork for over 20 years. It can be used as a sound proofing material for studios, sound stages, and auditoriums.
In the early 21st century it was discovered that melamine foam was an effective abrasive cleaner. When used for cleaning it works like extremely fine sand paper, getting into tiny grooves and pits in the object being cleaned. Rubbing with a slightly moistened foam may remove otherwise "uncleanable" external markings from surfaces such as crayon, magic marker, grease from painted walls, and grime from hub caps. I have personally used it on glass shower doors with good success.
There are two reasons why I would NOT suggest using a Mr. Clean Magic Eraser on a Travertine floor, shower, vanity, countertop or any other natural stone. Earlier I mentioned that the pH level of this product is between 8.0 - 10.0 according to the MSDS report. This alkaline cleaner is high enough in pH to eventually break down any sealers or protectants you may have on your travertine floors. Also this is an "ABRASIVE CLEANER". It is designed to work like sand paper - this will eventually scratch your once beautiful travertine floors. Because it is abrasive it would also scratch limestone, granite, marble, etc. A magic eraser has many uses but natural stone is not one of them. I hope this information hase been helpful to you.
