Cleaning with Lemon juice?

[Rivlas]

Been in my book again and found these uses for lemons.
Rust Stains: Dip lemon in salt and scrub to remove stains.
Emergency Shampoo: Mix 1 egg and juice of 1 lemon and wash hair in cool water
Hand lotion: Mix equal parts of olive oil, lemon juice, honey & glycerine and store in a bottle
To freshen a room: Stand a bucket of water containing slices of lemon in a smelly room
