Homemade Windshield De-Icer: Frugal Tip

Here’s a frugal tip sent in by a reader.

We always make our own windshield de-icer to save money.

Dissolve 1/4 cup of salt in one litre of hot water and add to an empty windshield washer fluid jug.

Add 500ml of Methyl Hydrate (about $10.00 for a 4 litre jug).

Fill to the top with water.

There you go – homemade window de-icer! Your $10 will get you about 8 jugs of fluid and you will save around $25 through the winter. Also, this will keep those plastic jugs out of the landfill.

    It sounds like a great idea but if w.w. fluid only costs $1.50 then you really aren’t saving very much besides saving plastic from going to the landfill.

  2. Gary says:

    Curious … what about the salt? Any extra rust on the car? I guess there is quite a bit coming off the road anyways. But nice idea to save money; I always thought about it. :D

    Will this not freeze? I live where the temp drops to -40 or more… I think i will stick to the store bought stuff… but thanks for the tip…. as for the bottles my hubby recycles and uses them as floats for water markers

    Where would you buy Methyl Hydrate??

  5. Noel says:

    Please remember to label the finished product properly and to mark POISON on the label, and make sure it’s stored in a container with a child safety cap. Methyl Hydrate is deadly poison. Regular windshield washer is also poisonous, and is labelled as such, and always comes in a child safe container. In general, poisons are best stored in their original containers, in case of accidental poisoning the product ingredients are on the label. Be Safe.

  6. Andy says:

    its a great idea but in reality after taxes on your 10 jug of Methyl Hydrate you save around $4.30 if you can get blue juice at 1.99 (1.99×8=15.92 -10=5.92-1.6( tax)=4.32 in Quebec sub your prov tax to recalculate its still 4 bucks and the blue stuff is usualy at 2.99 or more if not on sale so maybe you save $8 how much work is $8 worth to you???

    I am echoing Noel here. We use it on our brake lines in the logging truck…it is highly toxic (causes blindness and death)…through inhalation, ingestion and skin absorption.

  8. aaron says:

    I think this is just to de-ice windows and not actual windshield wipers. Water will likely freeze.

    Totally off topic question but I figured if anyone would know, it would be you.

    Do you know of any Canadian gift card exchange sites?

    I received some giftcards for Christmas but the store isn’t located in my province. It would be great if there was a site out there where I could exchange them for something I’d use.

    KDOT
    check out swapopolis.ca
    you can sell or trade gift cards there.

  11. Maxime says:

    Cardswap.ca is the biggest one I think!

    I just read this to my mechanic husband. He says this is a terrible idea. Methyl hydrate will destroy the paint on your car. He said spraying a salt based solution onto your windshield will only cost you tons of money in car repair bills. That salt water will rust anything metal and could destroy any electrical components or computer components that are often hiden in the area under where the wipers rest when turned off (in newer cars). Although I am sure many mechanics/garages would be very willing to fix the problems this could create, please save yourself the money of the repair and watch for washer fluid to go on sale, sometimes its as low as $1.49/jug! Not to mention, when you take your car in for an oil change, they should top up your windsheild washer fluid complementary!

  13. Mrs January says:

    Please note that this post is NOT about windshield washer fluid, but winsheild de-icer. They are two separate things.

  14. Stephanie says:

    I think it’s a pretty bad idea too. I work with saltwater all the time (aquariums) and it’s ridiculous how fast salt corrodes metal aquarium stands. I wouldn’t be putting it on my car.
