Black Swan's Rust-A-Way is a specially formulated compound that removes iron, rust, and other contaminants from most materials and surfaces. Ideal for use on tubs, sinks, water heaters, piping, tile, tools, chrome, steel and even white clothes.

THE PROBLEM
Iron is a natural ingredient in most water supplies. It is not noticeable because it is colorless. However, when iron is exposed to air it oxidizes and can form insoluble rust stains. These stains can appear on anything that has contact with water - toilets, water heaters, dishwashers, clothes that are washed in water, water softener cleaners, etc.

DIRECTIONS FOR IRON AND RUST REMOVAL
GLASSWARE, CHINAWARE, PORCELAIN, CHROME, CONCRETE, METAL SURFACES, ETC:
Wet a small area and rub on Black Swan Rust-A-Way on the area, moisten and leave on 5 minutes. Repeat several times if necessary. When iron and rust spots have disappeared, rinse surface thoroughly with water.

DISHWASHERS OR WASHING MACHINES:
With the machine empty, add 1/4 lb. of Black Swan Rust-A-Way instead of soap. Run machine thru normal cycle. Repeat if necessary.

FABRICS:
Dissolve 1/4 lb. or Black Swan Rust-A-Way in one quart or warm water and dip stained portion of clothing in the solution for a few minutes. Rub lightly and rinse thoroughly. Always test a small piece of the fabric first, as this treatment may harm or discolor some items.

TOILET BOWLS AND FLUSH TANKS:
Remove any in-tank cleaners and flush. For toilet bowls add 1/4 lb. of Black Swan Rust-A-Way to bowl. Saturate sides under rim with toilet brush. Let stand until stain is gone. Repeat as needed. For flush tanks raise water level above stained area. Add 1/4 lb. of Black Swan Rust-A-Way. Let stand overnight. Repeat as necessary.

DIRECTIONS FOR WATER SOFTENER CLEANER
Begin by preparing a solution of 1 lb. of Black Swan's Rust-A-Way in one gallon of warm water in glass or plastic container, then treat per manufacturer's instructions or by the type of softener.

SOFTENER WITH PRESSURE BRINE TANKS:
The best time to clean a softener is when the brine tank requires refilling with salt. With the water drained down in the brine tank, add the solution to the top opening. Fill with salt and continue operation as usual. Refrigerate softener.

SOFTENER WITHOUT BRINE TANKS:
Regenerate softener as usual, but add the solution through the opening along with the salt.

MANUAL SOFTENERS:
Backwash and regenerate with salt as usual. Add solution and let stand for one hour. Rinse thoroughly.

AUTOMATIC SOFTENERS:
Follow the manufacturer's instructions to regenerate the water softener. Pour the solution into the storage tank brine well and start regeneration cycle immediately. Allow the softener to finish regeneration.

CAUTION AND FIRST AID
Persons with respiratory problems should not use this product. Avoid breathing vapors after mixing with water. Good ventilation is important, as strong vapor will result. Never mix in a closed container.

Avoid contact with eyes and skin. If swallowed, give large quantities of milk or water. Call a physician immediately. In case of contact with eyes, flush with water for 15 minutes. Call a physician.

Contains Sodium Hydrosulfite and Sodium Bisulfite.

Subtle smell, works well to pick up dirt!
Size: 8 Fl Oz (Pack of 2)
Has a nice, light smell when added to the Eufy C20 water. Smell is short-lasting and very subtle, so no irritation to the animals in the house. Easy to use, a small amount is recommended, and I find it works well. Very good value for long-lasting use. 1 cap/water refill, and the water is much nastier than it was when using just water. Very pleased with this purchase.

Easy cleaning and pleasant scent.
Size: 8 Fl Oz (Pack of 2)
It works very well with the robot vacuum cleaner. It cleans the floor without damaging it, leaves no residue or marks, and leaves a soft, pleasant scent. It lasts a long time and doesn't cause any problems for the device. A very good product; I would definitely buy it again.

So Worth the Purchase !!!
Size: 8 Fl Oz (Pack of 2)
I was a little hesitant to buy this since it’s a bit pricey for a floor-cleaning liquid. Still, I decided to give it a shot because the floor in my new apartment smelled stinky due to the pet urine from the previous tenant. It turned out to be totally worth the investment! The floor gets much cleaner with this product—the dirty water tank ends up way dirtier than usual—and the Eufy mop pads no longer smell bad like they used to without this liquid. Also, just a little goes a long way. I fill the tank to the max with water and add about 15ml of this liquid. The instructions say to dilute 10ml in 2 liters of water, and my tank holds about 2.5 liters. So with one bottle, I can refill the tank around 31 times—which is a lot! Since it needs to be heavily diluted, I don’t notice much of the scent after mopping. I do wish it had a stronger fragrance, but it gets the job done, so I’m very satisfied!

Works good but doesn’t make the house smell nice
Size: 8 Fl Oz (Pack of 2)
This works good in our robot vac/mop however it doesn’t make the house smell good when the house is mopped, just when you put it in the water tank. The floors are clean and that’s all I really care about but would it be nice to smell freshly mopped, yes.
