If extra time on your hands has you thinking about cleaning those rusty garden tools, they’ll be ready for all that outdoor gardening you plan to do, grab the salt shaker and a lemon! Actually, the salt container may be more accurate. Coat any rusted areas with salt then squeeze lemon juice over it. Let this sit for 2-3 hours. Then use the lemon rind to rub off any residue. The acid in the lemon dissolves rust while the abrasive salt scrubs it away. Dry completely when finished. This can make good use of almost rotting lemons!
