Cleaning effervescent

Today’s post is a follow up on a post two days back which centred around a potential product liability claim involving pavers which had been effected by unsightly effervescent powder.

What is effervescence?

Efflorescence is the chalky white look that develops on many bricks and pavers from naturally occurring salts in the raw materials bricks and pavers are made from whether this be clay or concrete.

Typically it is not harmful to the pavers in the short term, however if untreated, overtime it could start to wear away the surface. As long as it is kept under control, the effect of efflorescence should not cause any major problems.

Efflorescence is easily removed with a cleaner specially used for concrete surfaces. My research and experience suggests it is best to monitor the condition of the bricks or pavers and act promptly if there is a noticeable build up of white residue.

The problem may well reappear particularly after rain or the pavers or bricks getting wet but here is a suggested plan of attack to clean Brick and Concrete pavers:

  1. The first step is to ensure that there are no damaged, lose or shifting of the pavers. Then you can start to remove any excess dirt and debris from the surface. You can do this with a broom by sweeping the excess waste into one spot and then you can dispose of it.
  2. If you notice any harsh stains like petrol, oil, grease or tire marks, then you can purchase a water based cleaning solution specially formulated for such stains. Apply this solution to the affected area and leave it for approximately 15-20 minutes.
  3. Then use a high pressured hose to rinse off the solution.
  4. Mix a small amount of a household detergent with warm water and apply it to the pavement with the use of a broom.
  5. Once the area has been covered evenly you can then rinse thoroughly with a hose and leave it to dry.

You may need to do this at least once a month to ensure your prone bricks and pavers are kept healthy, as well as nice and clean.
