Rust from pipes and radiators can be a problem, especially in winter, when a broken pipe disturbs more than one family. See how to clean rust from the house without needing a plumber intervention.
Lime and salt
Although this works with lemon also, a lime is more acidic without being corrosive to pipes. Sprinkle salt over the area full of rust and squeeze a lime over the salt. Use enough salt to cover all rust and leave it for 2-3 hours. Rub using the lemon peel, not a corrosive sponge, because you may further damage the pipe in question.
The already famous baking soda can help you get rid of rust. Make a thick paste of baking soda and warm water and apply to the entire area affected by rust. Leave on for 10-15 minutes and scrub the debris with a toothbrush or a soft brush.
Potatoes and dishwashing detergent
Cut a potato in half and grease its inner halves with dish detergent. The substances will create a chemical reaction that cleans rust. Leave the potato slices a few hours over the rust stains and then clean with water and a soft brush.
Get rid of rust from ceramic and enamel
Sometimes, tub or sink can have quite unsightly rust stains. Make a paste of borax and lemon juice and rub the rust stains with a pumice stone or a hard bristle brush.
Maybe you have a pliers, a patent or other tools full of rust. Put these tools in a container filled with diesel fuel. Leave them to soak overnight then remove the rust with a brass wire brush. Remove the oil with a cloth.
