Top 3 weirdest sources of stains

These seagulls could end up being a menace to your stone.

You're probably well aware of some of the more common types of stains that can afflict your stone: Water, oil, coffee, leaves, just to name a few. In fact, we wrote a whole article on it.

But stains can strike when you least expect, and from some surprising sources. The following are a few of the strangest stains you never would've thought you'd come across when doing surface cleaning.

Animal excrement

If you're going to have a pet around the house, it's going to need to use the bathroom. According to Virginia-based  waste pick-up service Doodycalls, every year, America's dogs alone create 30,000 tons of waste a day throughout the US – or 267,500 fully loaded tractor trailers. That's just dogs – factor in cats into the equation, plus wild birds that have no compunction where they leave their droppings, and at some point some animal excrement will get on your stone, whether inside or outside. 

Animal waste is usually acidic, which means that gift from Fido can cause unsightly acid etching on your stone. As well as preventing this from happening by training your pets, be sure to clean up any mess as soon as you find out about it. 

Acne cream

According to the 2012 census, there are more than 40 million people aged 10-19 in the US, making up 13.6 per cent of the total population. That's a lot of kids going through those awkward puberty years, stressing about the quality of their skin. 

Unfortunately for any of these households that happen to have bathroom sinks made of natural stone, acne cream happens to be a common source of stains for stones. According to Arkansas Stone Repair, this is because most acne creams nowadays contain benzol peroxide, a bleaching agent. 

Vomit

This is hopefully one you don't have to deal with very often. But whether it's due to indulging a little too much on St Patrick's Day, or simply a suspect takeout purchase, there are times when you might end up seeing vomit on your precious stone. 

As an organic source, the Marble Institute of America suggests it can leave a pinkish brown stain, and may even disappear when the source has been removed – particularly if outside. But if it's stubbornly gotten in there, you'll need to clean it off. You could do so with a combination of water and either detergent or ammonia, but if you want to be sure, use a product like HANAFINN Oxy-Klenza™.
