CLR cleans what many household products can’t. It dissolves and removes tough stains from the build-up of calcium, limescale and surface rust from hard water. You may not know what these are but chances are you’re living with them. Some examples where CLR can be used are;

• poor performing showerheads
• dishwashers (NON DRAWED)
• washing machines
• shower screens ( NON SYNTHETIC COATED)
• inside your kettle (WITHOUT EXPOSED ELECTRICAL PARTS)
• on your chrome & stainless steel taps inside and outside
• toilet bowls
• sinks
• on cloudy glass inside and outside
• chrome
• fiberglass
• stainless steel
• humidifiers
• surface rust stains on tools (CHROME & STAINLESS STEEL)

Plus many more.

If you have a specific surface that you would like to know can be cleaned with CLR, search the material on our Frequently Asked Questions to find the answer. If it is not there – contact us.

Use equal parts CLR to water, i.e. 1 cup CLR mixed with 1 cup water.

Yes, CLR is septic safe.

Wear household gloves. Mix equal parts CLR and warm water. Apply directly to stain with a brush, cloth or sponge. Rinse promptly with cold water. If the stain does not disappear use CLR full strength, wipe and rinse properly. For tough stains, the process may need to be repeated up to 5 times.

You can buy CLR at Bunnings, Coles, Woolworths, Metcash, SPAR (QLD ONLY), Mitre10, Home Timber Hardware and Blackwood’s. For a full list of stockists click here.

We recommend you do not leave on the stain for longer than a two to three minutes. Do not leave CLR on the stain and walk away from it. Always rinse thoroughly.

No. It is not recommended for use on cars as it may damage paintwork and/or interiors.

Unfortunately, we do not recommend using CLR on pool tiles. If CLR comes in contact with chlorine, it could result in toxic fumes. It could also remove the finish from the tile. We recommend consulting with a pool maintenance expert for their recommendation for products that are safe and effective

Calcium Lime Rust, more commonly known as CLR, is a household cleaning product used for dissolving stains, such as calcium, lime, and iron oxide deposits. Its main ingredients include water, lactic acid and gluconic acid.

In a well-ventilated area , mix equal amounts of CLR and warm water. Test on a hidden area before applying to the entire surface. Apply directly to the stain with a brush, cloth or sponge. After 2 minutes rinse promptly with cold water. Never leave CLR on an area for longer than two minutes. If the stain does not disappear, repeat this process and add more CLR solution as necessary. Never mix CLR with other household cleaners or bleach.

Mix one part (ex: 1 cup) CLR to eight parts (ex: 8 cups) water (for 10-12 cup automatic drip coffee makers). Run through coffee maker as if making coffee. Dispose of solution once product has run completely through the maker, then fill entire pot with clear, cold water and run a complete cycle twice. Instructions are for a regular 8-12 cup coffee maker. *Do not use CLR in coffee makers that hold water permanently. *CLR is not recommended for Gevalia, Keurig or Cuisinart coffee makers. *Do not use CLR in espresso machines.

Pour enough CLR to cover the bottom. Swish around in the pot or pan. Add one cup of warm water, allow mixture to soak for two minutes and thoroughly rinse with cold, clean water. Using a soft scouring pad while our product is sitting on the stains is recommended. Always check with the manufacturer of your coffee pots, pans and tea kettles first for their recommendations of products that are safe and effective on their materials.

Remove dishwashing rinse agent before using CLR. Pour a 1/2 cup of CLR into directly into the bottom of an empty dishwasher (no glasses, dishes, or flatware but the racks can stay). Run a normal cycle followed by an extra rinse cycle. Make sure there are no detergents or any other chemicals in the machine while using our product. . If your machine is HE (high efficiency) and/or ‘Water Saver’ we recommend using a 1/4 cup of CLR, instead of the normal 1/2 cup recommended for any other type of dishwasher. PLEASE NOTE: DO NOT USE CLR ON DISHWASHERS THAT HAVE DRAWERS. THE PLUMBING SYSTEM DOES NOT ALLOW CLR TO BE RINSED PROPERLY AND CLR CAN BE CORROSIVE IF NOT RINSED THOROUGHLY. For more detailed instructions read here.

Run your empty machine (no clothes) without detergent up to the main wash cycle, which is where the water stops and the cycle is about to agitate. Stop the machine and add one-half cup of CLR directly into the tub of the machine. Finish cycle. Run one additional full cycle (wash and rinse) with water only to rinse machine fully. If your machine is HE (high efficiency) and/or ‘Water Saver’ we recommend using a 1/4 cup of CLR, instead of the normal 1/2 cup recommended for any other type of washer.

For Front Loading Machines: Simply add a 1/2 cup of CLR to the soap dispenser (only 1/4 of a cup for HE machines). After the full cycle has completed, run an additional rinse cycle with just water. Make sure there are no clothes or other chemicals in the machine when using our product.

Use only on metal filters. Dilute equal parts of CLR and warm water into a plastic container. Dip the filter into the solution for about two minutes. Brush to loosen buildup and rinse with cold, clean water. Allow to dry.

CLR can not only remove the finish off of brass, aluminium and copper, but can also pit certain grades of brass, copper and aluminum.

DO not use CLR on any natural stone or marble (including cultured marble), terrazzo, coloured grout (any other colour than white), any painted, coated, sealed or metallic glazed surfaces, plastics (Food grade or soft), laminates, Formica, Slate, Titanium, Rubber, Corian, aluminium, galvanized metals, nickel, oil rubbed bronze, brass, copper, steam irons, leaded crystal, refinished tubs or any damaged or cracked surface. CLR may etch older sinks, tubs and tiles. CLR is corrosive. Avoid contact with wood, clothing, wallpaper and carpeting. Some laminated surfaces (counter tops) are coated with a synthetic surface which may be affected by rust removers; clean spills immediately. Always spot test first on an inconspicuous area.

We do not recommend putting CLR in a spray bottle. CLR is acidic in nature and the solution could “spray back” on your clothes or in your eyes or can get on materials it’s not intended to be used on.

When you take a shower does it feel as if the water stream is not as strong as it once was? It’s not your water pressure. It’s time for you to clean your showerhead. Over time minerals in the water build-up in the pores of your showerhead and either clog the pore completely or limit the stream of water.

Check out how to clean your showerhead in three easy steps.

We recommend using a 50/50 solution (equal parts) of CLR and warm water. If possible, remove the showerhead and submerge it in the solution for no longer than 2 minutes (using an old toothbrush on the face of the showerhead after it has soaked will assist in removing the mineral buildup) then rinse promptly and thoroughly with cold water. Repeat at full strength if necessary, rinsing thoroughly after each application.

We recommend using a 50/50 solution (equal parts of CLR and warm water) into a glass or porcelain bowl. Apply solution to the affected stained areas of the glasses using a damp cloth or sponge. After 2 minutes, rinse thoroughly with cold, clean water. If it seems that CLR helped a bit but the glasses are not completely clear, repeat at full strength if necessary. Due to the natural density and hardness of calcium as a mineral, the calcium can actually etch and embed itself into the material of the glass (usually present by having a cloudy appearance vs. spotty).

If it seems that the CLR did not help at all, the glasses may be etched and there is no remedy to remove the cloudiness. The cloudiness is actually tiny cuts made in the glass by deposits in the water. The only thing that may remove the etching is a jeweler’s polishing.

It is not recommended that CLR be used in steam irons. The acids in our products are not compatible with the components of steam irons, steamers or steam machines. We recommend contacting the manufacturer of your particular steam iron, steamer or steam machine for their recommendation for products safe and effective on their materials.

We do not recommend using CLR on a car. The acids in our product should not be used on aluminium or any painted/coated surface. You can safely remove rust from car wheels (if rims are made of chrome or stainless steel only, no alloys).

CLR should not be used in or on a car radiator. CLR may not be compatible with the materials associated with a radiator and it could have adverse effects if the CLR is not rinsed out completely.

We do not recommend using CLR to clean ice makers. The acids in our product are not compatible with the components of ice makers. We always recommend referring to the manufactures recommendation for safe and effective products to use on their materials.

We do not recommend using our CLR to remove oil. If CLR is mixed with oil, it will darken the concrete, which is very difficult to remove. To remove oil from concrete or blacktop, we do recommend using our product CLR Oil & Grease Remover.

Yes, CLR is septic safe. By the time it reaches the septic system it is neutralized with water. 

We do not recommend using CLR on or in any materials associated with a swimming pool. CLR should never come into contact with chlorine (or any other household chemical). It can create a poisonous gas and is not safe. We recommend consulting with a pool maintenance expert for recommendations for products that would be safe and effective.

Unfortunately, we do not recommend using CLR on pool tile. It could remove the finish from the tile. In addition, if CLR comes in contact with chlorine, it could result in toxic fumes. We recommend consulting with a pool maintenance expert for their recommendation for products that are safe and effective.

We do not recommend using CLR on any natural stones, especially marble (even synthetic). The acids in our product will remove the seal, penetrating the marble and can compromise the natural beauty of marble. Even synthetic marbles are coated and real marble dust is used to give the effect of real marble. If you spill CLR accidentally on these surfaces, make sure to call a marble professional for further instructions.

We do not recommend using CLR on galvanized metals. When a metal is galvanized, a Zinc coating is put over the metal (usually to protect it from rusting). The acids in CLR will remove the Zinc which could compromise the material.

We do not recommend using CLR on cast iron. The acids in CLR can compromise the metal.

We recommend using or disposing of CLR within 3 years. Make sure cap is securely fastened after each use.

CLR is safe on grass, shrubs, bushes, plants, flowerbeds and all types of flora. We strongly recommend you water the area where the CLR will run down, land, or touch before and after using CLR.

We do not recommend using CLR on any natural stones, including granite. The chemicals in the CLR can remove the seal and penetrate the stone.

ADVIL DO NOT RECOMMEND the use of CLR in or on any water heaters (tank or tankless); ALTHOUGH there is a website that does. Again,THE USE OF CLR IN A WATER HEATER IS NOT RECOMMENDED. The chemical make-up of CLR is not compatible with the materials or components of a water heater and cannot be thoroughly flushed through the water heater after 2 minutes. We recommend using what the manufacturer of the water heater deems safe and effective.

Yes. You can use CLR on vinyl siding as long as it is diluted and is thoroughly rinsed off of the surface in under two minutes. Studies have shown that the top coating of the siding will be affected if full strength CLR is left on the surface for five minutes or longer.

Yes, CLR is found to be safe on fiberglass. Always spot test first in an inconspicuous area. Begin with a mixture of CLR and water and progress to full strength if needed.

No, CLR should never be used on clothing. Please find an appropriate stain remover or laundry detergent. If CLR is spilled on fabric, you must rinse immediately. It may break down the fibres in clothing and/or fabric.

Depending on the material of the paver (non-coloured concrete is safe)it can safely be used. Always spot test in an inconspicuous area first. Make sure the pavers are not coloured, stamped, sealed or coated.

CLR should not be used to clean rugs or carpeting. CLR can break down the fibres in rugs and carpeting and pull the colour out.

Yes, CLR is great for cleaning pet bowls from food, grime and water deposits! Dilute equal parts warm water and CLR to clean ceramic, stainless steel or plastic bowls. Leave on for 2 minutes using a sponge or scouring pad to assist in removal of stains, then rinse thoroughly with cold water. While our product is non-toxic we recommend washing the bowls prior to putting food or water back in them.

While CLR is generally safe and effective in removing calcium, lime and/or rust from concrete, ALWAYS spot test in an inconspicuous area first. Apply a small amount of CLR to the spot test area using a damp cloth or sponge, let sit for no longer than 2 minutes, then rinse promptly and thoroughly with clear cold water. Let dry completely (usually overnight). If there are no adverse reactions between CLR and the concrete (change in colour or texture), it would be safe to use on the other affected areas of the concrete. Do not use CLR on coloured/tinted concrete, concrete poured less than 1 year ago, concrete that is stamped, sealed or coated. Note: Concrete is naturally made of calcium and run the risk of pulling the pigment out of concrete when using a calcium remover on something naturally made of calcium (such as CLR).

Although they both come from the fine CLR family, they are formulated differently and solve different cleaning problems. See each product label for recommended uses along with the helpful information provided throughout our web site.
