Rust stains are common for those who have a well with a high iron content. When the iron mixes with metal rust often occurs, leaving discolored marks on the porcelain it touches. Common areas of concern are porcelain sinks, toilets, and tubs.
Luckily, most staining isn’t major and can be removed. Some techniques use harsh chemicals that aren’t environmentally friendly. These are of particular concern if you are on a septic system as the chemicals can disrupt the organisms in your septic tank.
When it comes right down to it, old fashioned elbow grease is often your best bet. Shaw’s Pads® Toilet Ring Removers are a simple pad attached to a short handle that removes any number of stains. Simply scrub in short, vigorous strokes and watch the stain come off. The residue can then be flushed down the toilet.
As an alternative to Shaw Pads, you might try a pumice stick. Pumice sticks are a lot like the pumice stones you use on your feet. They use a coarse, natural material to remove the stain. However, you’ll want to avoid using a pumice stick on any fiberglass structures, as it can ruin the surface.
A stringent cleanser, such as ZUD, can also be used to remove rust stains. However, ZUD is not environmentally friendly. It uses oxalic acid to break down the stain. This highly potent acid is considered a poison. It can have devastating effects when introduced to a septic system or a sewage system.
As an alternative the ZUD, The Works is another chemical agent that can remove rust without requiring tons of elbow grease. It’s worth noting though, that this stringent cleanser is also not environmentally friendly.
