Fish tanks
Have you spent hours cleaning the fish tank trying to get rid of the hard water or scum that builds up on the glass? Try this; rub the inside of the fish tank with salt and a wet cloth to remove the build up. Don’t forget to rinse the tank well before placing the fish back in to the tank!
Vase cleaner
If you like fresh flowers, but hate to clean the small insides of the flower vase try this: using a very strong solution of saltwater and shake the vase around, then let it sit for about an hour. The strong saltwater will then eat away at the gunk at the bottom of your vases. Simply rinse your vase clean!
Pet mess
Did your pet have an accident on the carpet? You can clean up pet pee as soon as you see it by blotting up what you can, adding a large amount of salt to the area, (because salt can only hold so much moisture) and then wait ten to twelve hours. If the salt is not drying out, add more because this means you mustn’t have enough on the area to soak up all the pet pee. When the salt is dry, simply vacuum up the stain, the pee, and the odor all at one time! If you don't put enough salt you will end up with a stain. It is better to use too much on the first attempt than it is to have a stain.
Repair a wall
While this is not a cleaning tip I thought I would include it for you. If you have a hole in your plaster wall, you can fill the plaster hole by using equal parts of salt and starch, with just enough water to make stiff putty.
Rust remover
To get rid of rust on most anything, you can take a potato, cut it in half then dip it in salt. Rub the salted potato over the rusty area to be rust free again!
