Cleaning Rust Stains from Toilet Bowls

  • Rust is an oxide of iron that forms on the surface of the toilet as a result of exposure to moisture.  This can only be removed by two methods, chemical or mechanical removal.
  • You must understand the concept of pH to attack this problem.  The higher the pH,the more alkaline the solution conversely the lower the pH the more acidic the solution.  It is the acidic side of the scale that removes this oxidation as well as salts and soap scum.
  • Start with mildest acid and work your way up to strongest ones.
  • A mild acid is undiluted white vinegar.  Pour this on a World Of Wipers Terry Towel and rub hard across the stain.  Under no circumstances should you use steel wool as this will cause scratches.
  • Upon completion, neutralize with an alkaline solution.
  • If mild acids do not work, the next level of acid is 23% hydrogen chloride or 20% phosphoric acid.
  • Apply this acid and allow it to run down the side of the bowl.
  • Let stand for several minutes and then scrub with nylon brush.
  • Thoroughly flush when finished.
  • If chemicals do not work, you may want to try mechanical agitation in conjunction with mild scouring cream.
  • Apply cream to spot and agitate with scouring pad.  Always neutralize after cleaning.
  • If this does not work you may try a pumice stick.  Be sure to keep surface wet while doing this to avoid damaging surface.
