Dealing with stubborn rust stains on your linoleum floor? As a seasoned home cleaning expert, I've found a simple, natural solution that works wonders without harsh chemicals.
Grab half a lemon and a pinch of salt – that's all it takes for sparkling results.
It's quick and foolproof. Here's how:

1. Cut a lemon in half.
2. Sprinkle salt on the cut side.
3. Rub the stain directly with the salted lemon.
4. Finish with a scraping sponge.
The rust stains on your linoleum vanish completely! :-)
This method couldn't be simpler. The citric acid in lemon reacts with salt's gentle abrasion to dissolve rust effectively.
If traces remain, apply lemon juice and salt to the scraping sponge, then scrub. Bonus: it works great on plastic surfaces too.
