Water contains dissolved minerals and salts, when the water dries on the sink these minerals are left behind, causing deposits or water spots that are visible on your sink's finish. By drying your sink after rinsing, these spots are less likely to form. If you experience water spots or deposits, non-abrasive stainless steel cleaners or metal polishes will help to be rid of them. Wipe gently over the sink, in the same direction of the sink's grain.
Stainless steel sinks will scratch. Surface scratches will become less noticeable as your sink ages, the first scratches will always be the most noticeable. Over time, the sink will develop it's own unique finish as light scratches blend in to the sink's grain. Oliveri recommends the use of a bowl protector where possible to help protect the bowl from dents and heavy scratching.
Most minor scratches can be softened with a stainless steel polishing cream, rub with the grain, taking care not to rub in one area.
Accessories suited to your particular sink model will be listed as 'Included' or 'Matching' on the product page for your specific sink.
All Oliveri Stainless Steel sinks are made from 304 grade stainless steel, also known as 18/10. These numbers simply illustrate the percentage of chromium and nickel content present in the stainless steel. For example, 18/10 stainless steel means there is approximately 18% chromium and 8-10% nickel.
Chemicals, solvents and many household cleaners contain chlorides and acids which can react and damage stainless steel. Solutions of chlorine bleach, chlorides or citric acid found in many ordinary household cleaners can stain and corrode a stainless steel sink. Similarly, wipe up juices or acids from food immediately as they can contain citric acids which over time can etch the surface.
Do not allow liquid soaps or cleansers to dry on the sinks surface as they too can contain chemicals that can affect the high lustre of the sink.
Refer to installation instructions provided on the product page for your sink model as well an experienced installer.
The colouring is achieved through a Physical Vapour Deposition (PVD). The solid coating material of the stainless steel is evaporated by heat, while at the same time a reactive gas is introduced and it forms a compound with the vapour which is deposited on the steel as a thin, highly adherent coating. This method is environmentally friendly due to its non-use of hazardous chemicals as opposed to other methods of colouring such as electroplating or painting.
Coloured sinks should only be cleaned with soapy water and a soft cloth or sponge, then rinsed and towelled dry. It is highly recommended to use the wire bowl protector provided with the sink, to protect the bottom of the bowl. See our 'Sink Care' page under 'Support' for more advice on caring for you Spectra Sink.
The colour of the sinks is guaranteed, however it is not guaranteed against scratching and general wear and tear. The colouring is a solid coating on the surface of the stainless steel only and therefore if scratched harshly enough raw stainless steel will show through. However, by our testing it is difficult to scratch these sinks without deliberate scratching.
Stainless steel sinks
Garbage waste disposal are suitable for use with all of our stainless steel sinks.
Waste disposal units can be fitted to Oliveri’s Granite Sinks. However, faulty or damaged waste disposal units can cause vibration, which may lead to sink damage and will void warranty.
Avoid placing pots, pans or other hot objects in excess of 280° C on the surface of the sink (CAUTION! The bottom of a pot or pan just removed from the burner can reach temperatures of over 600°C).
Pots, pans and other hot objects must be placed on appropriate potholders (made of wood, metal etc.).
Avoid causing excessive “thermal shock” due to the presence of very hot and very cold objects on the sink at the same time.
Do not use the sink as a cutting surface: rather, use a cutting board made of timber or polyethylene.
The use of stainless steel dish baskets or surface protectors (which can be purchased together with the sink) can reduce the risk of accidental damage.
Do not use harsh abrasive substances or metal cleaning pads (steel wool) to clean the sink because they may scratch the surface, making it susceptible to stains.
Heavy or pointed objects that fall on the surface of the sink can damage it.
Do not pour alcohol, acids or any solvents in general into or onto the sink because they could react with the chemical structure of the sink and damage it beyond repair.
Simply clean the sink regularly with warm water, a liquid dishwashing detergent and a soft cloth.
Generic stains should be removed immediately.
Marks caused by foods or liquid which can stain easily, e.g. tea, coffee, fruit juice and the like, should be removed immediately with hot water and a non-abrasive cleaning product. If necessary, a nylon brush can be used to assist with stain removal.
Cleaning powders and creams which are highly abrasive should not be used.
No, stainless steel sinks do not rust, however they may appear to if they come into contact with contaminants. Rust marks in stainless steel sinks can usually be a result of one or more factors. These are some of the more common causes:
Steel wool pads: Often used for cleaning these will leave steel deposits on the sink which will cause rust marks to appear.
Ordinary steel containers, utensils or kitchen ware: Items like tin coated steel cans or pots can leave rust marks and stain the sink.
Iron deposits: Often found in water, iron particles left on the sinks surface can then leave rust marks.
Bleaches or chemicals: Solutions of chlorine bleach, chlorides or citric acid found in many ordinary household cleaners can stain and corrode a stainless steel sink.
Rust marks are caused by deposits on the sinks surface. We recommend lightly scrubbing the stains with a mild cleanser in the direction of the sink's grain. Particles need to be completely removed in order to stop them from returning. It is important to thoroughly dry the sink after cleaning. In cases where the problem is particularly persistent it may take several attempts to restore the sink to its pristine condition.
Oliveri granite sinks are made of 80% granite and quartz particles and 20% acrylic resin.
Yes, all Oliveri taps in our current range are WELS approved. The WELS Star Ratings and nominal flow rates (litres per minute) for each tap are listed in our literature and on the product page for each tap.
Up-to-date WELS Registration details can also be found on the WELS website. http://www.waterrating.gov.au go to “Search for a product” and select “Taps”, click “go”, select Oliveri in the “Brand names” box, then click “Search”
Dezincification Resistant (DR) brass, in compliance with AS/NZS 3718
The majority of our taps are made in Italy - refer to our catalogue or website for individual product information.
These components are powder coated.
The material is called “Ecoflex”. It is a polyethylene, tested and conforming to requirements for use in the area of drinking water systems.
No, they are only suitable for mains pressure systems.
The recommended operating pressure is between 100 - 500kpa (1 - 5 bar).
The maximum operating pressure on all Oliveri taps is 600kpa (6 bar).
Pressure limiting valves must be fitted, if operating pressures exceed 600kpa (6 bar). Failure to do so will void the warranty.
The WELS (Water Efficiency Labelling Scheme) Star Rating is based on the nominal flow rate of the tap, during testing. A tap can be rated between 1 Star and 6 Stars.
The higher the star rating, the higher the water efficiency, but the slower your sink will fill.
The warranty is 5, 15 or 10 years, depending on the model chosen. For further details refer to our 'Service and Warranty' page.
No, all Oliveri mixer require mains water pressure.
