Tenax USA/Lustro Italiano

Lustro Italiano is a product line of cleaning, maintenance, and restoration products designed for use on natural and engineered stone surfaces.

Why Tenax Created Lustro Italiano Products

Tenax keeps an eye on the stone industry and develops products and product lines to accommodate the trends as they occur. Through research and development as well as product development and testing Tenax sees and fills the needs of stone professionals in the industry. Four specific needs moved Tenax to develop the Lustro Italiano product line. They are:

  1. Educate
  2. Quality
  3. Price
  4. Specifications

Tenax saw the role for a product to fill those four needs and they went to work on developing the Lustro Italiano product line.

Educating Consumers

Tenax receives calls on a daily basis from homeowners who are frustrated from the lack of knowledge of how to clean, maintain, seal, or repair stone installed in their homes.

So many contractors install beautiful, expensive stone for homeowners and fail to educate the owner of that stone about how to take care of their investment. Lustro was created to educate the homeowner about caring for and maintaining stone surfaces that have been installed in their home. In conjunction with this information, the Lustro Italiano product line serves as a brand of products made for the homeowner.


We researched where consumers purchase the majority of their stone cleaning and maintenance supplies. This research revealed the level of quality consumers were getting for the prices they were paying.

Unfortunately, we discovered that the quality that consumers were getting was very poor. Stone cleaners and sealers we found wer so watered down that they were ineffective. In fact some products marked as "stone cleaners" contained ammonia.

Harsh chemicals like those destroy sealers that come with stone materials. In fact, they even etch and remove the polish off of certain stones such as marble!

Being the manufacturer of premium grade products, Tenax decided to take its industrial line of professional grade products and put them into a consumer package. These Lustro products by far exceed the quality of anything that can be found at a super market, big box, or super store (unless they are carrying Lustro Italiano)!


It's one thing to get an inferior product. But it is another thing to pay premium price for that inferior product. Lustro Italiano products offer products with uncompromised quality. Lustro Italiano products are premium, professional grade cleaners, sealers, polishes, and stain powders that cannot be compared with what is purchased from our competitors. Tenax Italy owns the factory, produces their own raw materials, and can control 100% of the manufacturing process.

We know what goes in to our products. And we do not compromise quality for price. Lustro may not be the cheapest on the market. But it is the best! No watered down products!


Many cleaners and polishes on the market for natural stone were actually designed for other materials such as:

  • Solid Surface
  • Glass
  • Wood
  • Stainless Steel

Manufacturers have just added stone to the list of materials their products clean without any knowledge of the composition and materials that make up stone. On the other hand, Tenax has been 100% exclusive in the stone industry for over 50 years. Furthermore, Tenax have on staff chemists who work directly with the stone quarry producers in creating adhesives and chemicals for products specifically for each class and type of stone.

The Lustro Itliano product line has used the invaluable knowledge of its resources to create products specifically designed for stone. Lustro Italiano cleaners and polishes, as well as sealers and stain removers, even polishing powders have been specifically designed for stone. We are a stone cleaner, polish and maintenance company.
