How to Decalcify Lime Deposits

Lime deposits, also known as lime scale, is formed by the minerals in water that collect on the surface over time. Lime deposits are found in and on anything that holds water regularly. Bath tubs, sinks, faucets, coffee makers, pipes and water spouts are some of the places where you will find the lime deposits. The mineral buildup should be removed before it damages the surface it occupies or causes a clog. To remove it, you will need to decalcify the limescale.

Instructions

  1. Faucets, Spouts and Shower Heads

    • 1

      Pour a mild acid (lemon juice or vinegar) into the small container. Place the container up to the faucet, shower head or spout so that the area with the lime scale is submerged in the acid.

    • 2

      Hold the container to the faucet while it decalcifies the lime deposit or make a support. The lime deposit will need to be submerged for a few hours, so cradle the container in the towel and tie the towel at the top of the faucet. The towel cradle should hold the container of acid to the lime deposit.

      Check the lime deposit after an hour. Take another towel and try to wipe away any deposits that seem to be left over. If the deposit is still stuck on, place your cradle back on the faucet for another hour. Repeat this until the deposit is completely decalcified.

    Floors, Small Objects and Appliances

      Place an acid of your choice (lemon juice or vinegar) in a small container. Pour a small amount on the floor and scrub with your cleaning brush. You may need to let the acid sit for an hour to decalcify the deposit completely.

    • 5

      Put smaller objects that are covered in lime scale in the container of acid to decalcify while submerged. Let it sit until the deposits are gone.

      Pour lemon juice into the coffeemaker's water reservoir or pour a cup of vinegar into the wash basin of the washing machine. Turn these appliances on so that they run a full cycle. The acid will be exposed long enough to remove mild lime deposits that are common in these appliances.
