Instructions

  1. 1

    Open all windows in the area of the clogged drain.

  2. 2

    Pour the 2 cups of the Thrift Super-Pro Acid down the drain that is clogged. This product offers a 95 per cent sulphuric acid concentration, which is all that is sold on the market to the public. Allow this to sit in the drain for at least one hour before attempting any other fixes.

  3. 3

    Insert the power snake into the clogged drain and extend to push the clog out of the drain pipe. This will move out of the way any lingering clog that the acid did not penetrate.

  4. 4

    Recoil the snake and remove from the drain.

  5. 5

    Flush the drain with water to make sure the drain is clear, and use as you normally would.

Tips and warnings

  • This product, as many that contain sulphuric acid, is for professional use only. There are products on the market that contain sulphuric acid, but not at a high enough concentration to be of use. If you know a plumber, or are a licensed plumber, you can purchase this product online or in stores. Another great publicly sold product is the Drain Flow Inhibited Sulfuric Acid Drain Opener. This product is activated by water and causes it to heat to 82.2 degrees Celsius, which dissolves grease and hair along with most other clogs. This can be purchased online or at local hardware stores.
  • When using any acid, clean up spills immediately. Always use proper ventilation when using acids because the caustic and corrosive material cause an irritating and at times debilitating odour.
