Contrary to popular opinion, bleach, although effective in treating surface mould is not the best way to treat it. The Australian Environmental Mycology Laboratory recommends that surface mould be vacuumed up with a HEPA vacuum, then to wash the area with an 80/20  solution of water and vinegar. White vinegar treatment is known to be the most effective means of removing mould. If there are particularly stubborn stains the same laboratory recommends using bicarbonate soda to remove them.

How to remove mould from silicone sealant

Due to the way it dries and because of how it is usually positioned, silicone presents some unique problems for mould removal. To get the job done with as little fuss as possible it is suggested that you have the following implements and ingredients at the ready.

  • A basin or bowl 
  • Either a solution of vinegar and water or bleach
  • Baking soda
  • Cling wrap
  • Rubber gloves
  • A paintbrush and possibly an old toothbrush

Mix the bleach or vinegar solution with the baking soda to make a paste. Use the paintbrush to apply the paste over the silicon. You can use a toothbrush to access any hard to reach spots.Then, apply cling wrap over the paste and allow the solution to stand for two hours. Get rid of the wrap and then wash the solution off.

If that all sounds a little difficult, then it might be best to call in an expert to take care of your mould problems.

How to remove mould from drains and walls

Often, the first place that mould inevitably appears around is the drain. From there it often spreads to the shower floor and walls.

If you choose to use bleach, make sure that the bathroom area is well ventilated and you wear protective gloves and clothing.

Fill the bottle with your solution and then spray over the drain area, visible mould and  shower walls.  Let  the solution stand on the walls and dry for about 10 minutes. Then use a scrubbing brush to remove the mould from the affected areas. When you have finished scrubbing the solution and and mould away, you should be left with a sparkling drain and pristine clear walls

Why you should consult with an expert

As well as being hard work and messy, working with mould can be  quite dangerous, particularly in areas that are not well-ventilated such as shower cubicles and bathrooms. Microscopic mould spores can be dislodged at any time and easily inhaled by the person removing the mould. This  can make it quite the health risk  for the do it yourself mould treater.

Even if the job is done effectively at a surface level, it is unlikely that most homeowners will be able to pick up the source of the mould outbreak and effectively deal with that. If mould is occurring in shower areas it could well be evident in other areas of the home as well.  Only by  consulting a mould expert can you be sure that your home will be rid of the mould.
