Glasses in dishwasher

How to Get Dishwasher Marks Off Glasses

You’re tired of opening your dishwasher to find your glasses smeared in white marks. I know, I feel you. All us dishwasher-users from areas with hard water do, but what exactly are these stains, what is the right way to remove them and how do you prevent them?

What are these white marks on your glassware?

High levels of magnesium and calcium in the dishwasher water can cause limescale buildup which show up as marks on your glassware.  Although there are measures you can take to minimise the chances of it happening again, you can continue to use the glasses as usual as they aren’t “dirty” as such.

If you’ve left them like this for too long, however, you will not be able to undo the damage which has been done so it’s best to treat it as you would a stain—see to it immediately.

How to remove the stains

1. Clean glasses individually with lemon juice

As lemon juice is a natural acid, it can work wonders when it comes to removing mineral deposits. All you have to do is pour some lemon juice onto a cloth and clean the glass as you would with a sponge if you were washing by hand. You can also use white vinegar to achieve similar results. If the stains still don’t seem to be moving, try adding the lemon juice to some salt to create a paste and dip your cloth in and try the same method again.

2. Make a baking soda and white vinegar paste

Just like with the lemon juice and salt: mix together a paste using baking soda and white vinegar. Smear this paste on the areas of the glassware that needs cleaning and leave to sit for around 10-15 minutes. Wipe away the excess and the mineral deposits should be gone!

3. Grab some toothpaste

Great for whitening teeth but also a great component in ensuring clean glasses. Take an old toothbrush and as you would with your teeth (maybe not as harshly) scrub the glassware on the areas you’re trying to target. Afterwards, soak in soapy water (plus vinegar) before rinsing.

How to prevent stains

Now that you know how easy it is to remove these stains, it may be tempting to keep this at the back of your mind until it happens again but, like most things, it’s better to tackle the issue at the source than to deal with it as and when they pop up. Here’s how to do just that:

1. Salt, salt, salt

Another reason why salt works so well to remove these limescale marks is because this is exactly what your dishwasher has, most likely, been missing. Somewhere on your dishwasher there should be a salt indicator. Make sure you’re always on top of it and you’ll see a drastic improvement in the overall finish of your glassware.

2. Combat mineral deposits with household products

There are some great products out there made to combat the limescale build up in your dishwasher. Make sure you choose a commercial product that it specifically formulated to target this issue and use it as maintenance every few weeks.

How often do you use your glassware?

If you only use your glassware on special occasions, it might be worth simply washing all of your glasses by hand, as this avoids this problem completely. Just ensure you wash them thoroughly and polish them afterwards.

Overall, mineral buildup isn’t something to lose your head over but can be easily avoided using these tips. Do so and your glassware will be glistening like they were on the day of purchase!
