Keep Your Terrazzo Floors Beautiful

6. Wipe up spilled materials quickly so staining has no chance to occur.

Remove Those Stains

No flooring material has yet been developed which is completely stainproof. Properly sealed terrazzo is stain-resistant; and if you wipe up spills promptly, you should have few problems with staining. However, some staining will eventually occur, as with any other flooring material.

Ask yourself two questions before attempting to treat any stain:

  • 1.

    What caused the stain?

  • 2.

    What is the least harmful way of removing it?

Chemicals should be used only as a last resort in removing stains. Remember that a certain method may be effective on the stain but harmful to the floor itself.

Stain removers act in one of three ways: they either dissolve the substance that caused the stain or they absorb or bleach the stain. Solvents such as carbon tetrachloride dissolve grease, chewing gum and lipstick; absorbents, such as chalk, talcum powder, blotting paper or cotton, absorb fresh grease and moist stains; and bleaches, such as household ammonia, hydrogen peroxide, acetic acid or lemon juice, discolor or fade stains.

Caution: Follow directions carefully when you use chemicals to remove stains. And, always "remove the stain remover" as soon as its job has been done. Remember that many of these substances are on the "Not recommended list" for general floor care, but must be used if the stain is to be removed.

Try the following methods for some of the more common types of staining. Try the first method listed first, and go to the second only if this doesn't work. For unknown stains or heavy staining, consult a professional.

The chemicals listed may be purchased at drug stores or at chemical or laundry supply houses. Where poultices are recommended, apply them about one-half inch thick, and let the mixture dry thoroughly before removing.


Caution: Always wear rubber gloves when using the methods marked with an asterisk (*).
