This Top-Rated Rust Remover Spray Is Perfect For Cleaning Indoors & Outdoors

Rust is commonly associated with metal; a logical connection, since metal that is exposed to water and air will yield corrosion in the form of rust. However, for some homes, rust stains form even in the absence of metal, on everything from bathtubs and toilets to the siding on your home. This is due to the accumulation of minerals from hard water, which sticks to surfaces, resulting in that gross orangish-brown stain that you're all too familiar with. Unfortunately, removing rust stains is far easier said than done: it requires a lot of elbow grease and even then there's no guarantee that your efforts will yield decent results. But an affordably priced product could make your rust stains disappear — literally.

Whink Rust Stain Remover ($14.95 on Amazon) is a spray-on rust-removing product that can be used on mineral stains, no matter how bad they are. The spray is formulated with a foaming property so it will stick to the sides of the surface in question and work away at the stain until it has disappeared entirely. This spray is safe for use in septic systems (a huge plus as many older homes on septic systems struggle with hard water and mineral buildup) and will not harm your home's pipes — but you should avoid using Whink on metal or wood, which can be damaged by it.

Before you begin spraying with abandon, remember to read the manufacturer's instructions carefully. You should avoid using Whink without skin protection, as it can burn your skin or harm your eyes. Also be sure to crack a window or use it in a well-ventilated room as it can be dangerous if inhaled. 

Begin by spraying the Whink onto your rust-stained surface and leave it until the stain has disappeared. Rinse the surface after the stain has lifted and repeat as often as needed when the stains return. Depending on how bad the stain is, you may need to leave the spray on for a period of time, which will let the cleaner dissolve the rust and mineral buildup. Bear in mind that the product specifically states that no scrubbing is necessary.

In addition to using Whink on your toilets and bathtubs, you can also spray it directly on stained siding or other exterior surfaces of the home that have suffered from the dirty-looking stains. If you have lost your favorite piece of clothing or a crisp white towel to an unsightly rust stain, this product is also suitable for use on fabrics. While Whink can't be used on metal, remember that WD-40 is a tried and true method for lifting stubborn rust spots from metal tools or surfaces.
