There are several methods for removing rust stains from surfaces. Good old grandmother’s tricks often prove effective. However, sometimes the use of cleaning products is required, especially when the stains persist.

1 – AGAINST RUST ON PORCELAIN
To remove rust from the toilet bowl, pour a can of coke in it and leave it to act overnight. The next day, scrub the bowl with an old toilet brush, then rinse.
To remove rust from the sink, mix borax and lemon juice to make a smooth paste. Spread it on the stain, then scrub gently with an old toothbrush. Repeat the operation as many times as necessary.

2 – AGAINST RUST ON PLASTIC
