Cleaning of Cultured Marble

Removing stains from cultured marble should be easy if the product had a quality "gelcoat" finish correctly applied at the time of manufacturing. Stain resistance is a great benefit of "quality" cultured marble products. Stain resistance testing is a part of most code requirements.

If the stain is tea, juice, or coffee, the stain should be easily wiped up with a damp sponge and household cleaner, such as Windex. Do not use an abrasive cleaner, as this will lightly dull the smooth and shiny surface. The smooth surface makes the cleaning process easier.

Maintenance of cultured marble products is enhanced if an automotive wax is applied occasionally, usually twice a year.

If the area has a chemical stain such as fingernail polish removed, which has been sitting on a covered area and stained the counter top, try leaving the area uncovered for a period of time. Sometimes the chemical will evaporate from the gelcoat, or contact the manufacturer for professional service options.

If the stain is from hard water or mineral deposits, then try using a cleaner for removing iron, calcium, or other such mineral deposits that are in your water supply. Most cleaning chemicals will not damage the gelcoat as long as extended or prolonged standing of the chemicals is not allowed (be sure to read warning labels).

Cleaning Instructions for Cultured Marble

1. Turpentine, denatured alcohol, or paint thinner will remove paint, tar, and difficult stains from the surface. Do not use turpentine or paint thinner on the hydrojets or plated components - damage to the plastic coatings may result.

2. Scrape the cultured marble surface with a wooden edge to remove plaster. Do not use wire brushes or metal tools on any part of the cultured marble surfaces.

3. Use liquid detergent to remove construction residue.

4. Liquid cleaning compound (such as is used for cars) with a light application of liquid wax or paste will restore dull surfaces.

5. Clean plated Hydrojet surfaces with water only. Do not use any ammonia bases or abrasive cleaners as this will deplate Hydrojet plating and void the warranty on plated finishes.

Regular Cleaning

1. Because of mineral deposits and soap scum, it is important to clean your cultured marble parts regularly.

2. For normal cleaning of marble surfaces, do not use abrasive cleaners, steel wool, scouring pads, scrapers, or sandpaper on any part of the surfaces.

3. Use nail polish remover to dissolve adhesives. Do not use polish remover or/and acetone on the hydrojet or metal hardware. (Nail polish remover and acetone are highly flammable, so ventilate the room and keep these materials away from heat and flames.)

4. Clean under the jet faces by unscrewing the faceplates. (You may also be able to clear obstructions by taking out the orifice with a standard 9/16" socket.)

5. Purge system once a month to clean pipes with Calgonite or whirlpool cleaner kit.

a) Fill tub with lukewarm water.

b) Add 1/2 to 1 cup of Calgonite depending on size of tub. Turn on system for 10-15 minutes.

c) Empty water from bathtub.

d) Fill with lukewarm rinse water and run system for 10-15 minutes. Then drain system.

To Enjoy Your Whirlpool Tub

1. Check to make sure the hydrojets are not pointed upward!

2. Do not turn on the system until the tub is completely filled (at least 1 to 2 inches above the highest jet).

3. Fill the tub with cool water if you want an invigorating refresher any time of the day or fill the tub with warm to hot water if you want to ease muscular tension and aches or if you just want to relax.

4. Limit your first hydrotherapy whirlpool to less than 10 minutes.

5. Use the pneumatic switch on the tub to turn the system on or off at your convenience. After the whirlpool action is finished, the tub may be used for regular bathing purposes.

6. Localize the massage action by placing your finger on the eyeball for the jet and rotating.

7. Alter the pressure of the massage action by using the air control(s). For more air, dial the air control to the "open" position. For more water, turn the knob to the "closed" position.

8. Do not allow any small objects such as toys or marbles to enter the jets or suction. Children should not be allowed to operate the whirlpool without supervision.

Caring for Cultured Marble Vanity Tops/Tubs/Showers

1. Water temperatures exceeding 140 degrees may cause cracking or crazing. (Temperatures above 140 degrees are dangerous to the skin even for very brief moments)

2. Protect the surface of this cultured marble with regular applications of paste wax or car wax.

3. Clean only with liquid cleaners of a non-abrasive type. Example: Scratch Guard by Turtle Wax/409/etc.

4. To remove surface scratches, buff with a portable buffing wheel and automotive type cleanser or rubbing compound.
