Since Coke is acidic, it’s able to remove rust stains from concrete. But you can also use vinegar or lemon juice to do the same job and serve as an efficient concrete floor cleaner. The trick is to allow the undiluted acid to dissolve the rust.
This may take ten to fifteen minutes. Then you’ll need to scrub the spot with a stiff brush. Finally, rinse thoroughly with cold water so that the acid doesn’t continue to eat away at the rock. You can also use this method to try and make a homemade rust remover, too.
Not only will Coca Cola take care of the rust on your concrete, but you can also use it to clean a cast iron grill pan or grill grates. Soaking cast iron in Coke for a while loosens grease, grime, and rust so that when you take it out of the soda, you can just rub it clean. How easy is that?
However, if that solution doesn’t work as well as you hoped on your concrete, there is another approach you can try. First, mix liquid laundry detergent and baking soda into a runny paste. Once you’ve applied it to the stain, let it sit for an hour. Don’t allow it to dry. Then scrub and rinse.
Additionally, this technique can remove greasy spots, too. Coke might work also on some light rust spots on the surface of your toilet or sink. However use simple household ingredients like white vinegar, baking soda, and lemon juice to make your own rust remover. Here are some recipes to clean rust stains from sink and toilet.
If you have a pressure washer, it can speed up the process and make a simple DIY concrete cleaner. Start by treating the stain with either an acid or the paste. Once you’ve waited enough time, hit the rusty spot with a strong blast from the pressure washer.
It should save you the effort of scrubbing with a brush. But it may cause that area to appear cleaner than the rest. In that case, you might decide to wash the whole floor to match.
