Hello, DIY enthusiasts! Today, we're going to play detective in the world of washing machine woes, specifically—why our trusted washer sometimes leaves stains on our beloved clothing. I'll be your friendly neighbourhood repairman guiding you through this sometimes baffling but surely fun journey. So, buckle up, it's time to put on your DIY detective cap!

Chapter One: Grease or Oil Stains

One of the prime culprits behind washer-related stains are pesky oil or grease marks that seem to appear out of nowhere. If you see dark spots appear on your clothes post-wash, it's time to eyeball your washer.

Typically, these oil/grease spots are not the doing of any culinary masterpiece gone awry in the laundry room, but due to something less appetizing—faulty bearings. When these guys break down, the result is an unwelcome oil leak that ends up staining your clothes. A sudden increase in noise from your machine is a key symptom of this. As our washing machines age, they do demand some care.

Your trusty repairman's advice: Replace those aging bearings! You might need a professional for this job, but it will ensure your machine remains grease-stain-free.

Chapter Two: Detergent Stains

Up next, we have a common stain suspect: detergent! Sometimes, there's such a thing as too much of a good thing. If you've been noticing light or white streaks on your clothes, chances are your soap is playing the villain.

But fear not! This friendly neighbourhood repairman has some easy solutions. First, try using less detergent. Check those manufacturer guidelines and stick to the suggested amount. Second, ensure you're using the right sort of soap for your machine. If you've got a high-efficiency type, high-efficiency detergent is what you need. Third, don't forget the power of the warm wash. Cold water may not be able to fully dissolve the soap, leading to those dreaded streaks.

Chapter Three: Rust Stains

Are you spotting reddish-brown stains on your fresh laundry? The suspect could be rust. An old washing machine or one with chipped enamel in the drum can be a hotspot for rust.

But before you panic or begin googling where to buy a new washing machine, try this home remedy: fill the washer with warm water and add a product designed to remove rust stains. Run the machine through a cycle, then wipe clean. For stubborn rust, use a mild abrasive like baking soda mixed with water, and scrub gently. If all else fails, it might be time to call in professional help to re-enamel the inside of the drum.

Chapter Four: The Mystery of the Random Stains

Sometimes you can't figure out where the stains are coming from. Is it a shopping receipt forgotten in a pocket? Maybe some loose colour from a new piece of clothing?

Avoid these mystery stains by checking pockets before throwing clothes into the washer. Also, washing new, richly-coloured clothes separately the first few times can avoid inadvertent stain transfer.
