Rusty doors and windows, especially exterior ones, are one of the biggest problems faced by people with these elements in their homes. Maybe it’s not a big deal if it’s just cosmetically difficult, but the damage doesn’t stop there.
Damage caused by oxidation of the metal of windows and doors means that over time the material of the components wears away, weakening them until there is an effect that prevents them from performing their function, or problems arise. Insecurities force us to make changes prematurely.
In this way, since the oxidation of the metal greatly shortens its service life, it is necessary to remove the oxide on the surface of this worn door and window. Here we tell you why this happens and how to remove rust the easy way without investing in paint bills.
Why do metal surfaces rust?
Rust on surfaces such as steel is the result of an electrochemical reaction that occurs when water, such as rainwater, comes into contact with this material, especially the iron in the alloy.
Generally, when iron (Fe) particles are exposed to ambient oxygen and water, they oxidize, resulting in the formation of iron oxide (Fe⁺⁺) and molecules called hydroxide ions (OH).
Hydroxyl ions react with Fe⁺⁺ to form iron oxide (FeOH), commonly known as rust, which is a red/brown substance that forms on surfaces and causes corrosion.
How to remove rust from windows and doors without painting?
Many times, there are not the resources to invest in restoring these surfaces through painting, however, to prevent rust from deteriorating your windows and doors, you can practice these simple and inexpensive tips that will help you effectively remove rusted metal.
Aluminum foil, your best ally:
The aluminum foil paper commonly used in the kitchen has a very strong ability to remove rust. To do this, you simply cut aluminum foil into squares or strips about 10 cm on each side, make small balls, moisten them in water for a while, and rub them on the oxidized metal. Do the latter until you think the rust is completely removed. When finished, clean the surface thoroughly with a rag.
Salt and Lemon:
This works better for small areas. To do this, you’ll need to add a pinch of salt to the affected area, followed by lemon; the amount of both will depend on the size of the surface you’re removing rust from. Let the mixture work for at least an hour, wipe with a brush, and finally dry with a cloth.
vinegar:
Another kitchen ingredient can also help us remove rust. To do this, you just need to put white vinegar on the damaged surface, for this you can help yourself with a brush and let it work for as long as possible, up to a day. Afterwards, scrub with a brush or sponge to remove rust. You can also do the same steps with Coke.
baking soda:
To use this trick, you’ll need to make a paste of baking soda and white vinegar. Use a tablespoon of baking soda and a touch of white vinegar to make a paste, apply it to the rusted surface, let it sit for a few minutes, rub it with a brush or sponge, and then clean the surface thoroughly.
