Remove rust with vinegar
Dip the rusted item in undiluted white vinegar. If the object is too large to do so, generously spray or apply vinegar to the rusted area. Let the vinegar soak in for at least 30 minutes. If you have a lot of rust, a longer soak is probably necessary. If that's the case, start with a couple of hours. Then check the progress.
Remove the item from the vinegar bath and use a brush to remove any remaining rust from the surface. An old toothbrush or nail brush works great for this. Later, rinse the item and dry it completely. Repeat the process if rust remains.
Remove rust with lemon juice
Mix borax and lemon juice to make a paste. You can also use baking soda if you don't have borax on hand. Apply the paste on the rust and let it sit for at least 30 minutes (longer for more rusty objects). If the paste starts to dry out, simply sprinkle some water on it to re-moisten it.
Use a brush (a toothbrush works great) to rub the paste onto the rusted object. Scrubbing should remove rust immediately. If you still see some rust, just repeat the process. You have to make sure to rinse and dry the item thoroughly before using it again.
Remove rust with baking soda and a potato
Cut a potato in half and sprinkle the cut side with salt or baking soda. Next, rub the cut side of the potato over the rusted area. The acid in the potato will lift the rust and the salt (or baking soda) will help remove it.
If you are trying to remove rust from your kitchen knives, dip them in a potato and let them sit while you go about your day. When you take the knives out of the potato, the rust should be cleaned immediately. Wash and remove the item you cleaned before putting it back into use.
