Spray cleaning brick-wall fence

As mentioned before I bought a pressure washer.

But what I didn’t expect is the anti-mould bathroom spray to be so effective on the brick.

As this is a rental house I shouldn’t even be doing this but I’d rather clean what I can instead of waiting for the not-so-quick to respond owner to do anything about it.

Black black is also the name of chewing gum. But this is just gross.

Bubble bath for the mould.

I think I left this on for days until my next opportunity to power wash the brick-fence.

The next time the fence was sprayed it bubbled out the brick for a while. Spraying until it all came out took a minute.

It this better? Well by comparison with the other untreated brick.

I’m surprised just how well that worked. For less than 100¥ for a bottle of anti-mould spray.

I would do the whole fence but it’s just worth the time and effort to clean the whole thing again.

Besides, the owner is responsible.

  • Does this damage the brick? I have no clue.
  • Does it work? Yes
  • Is it cheap. Yes
  • Do I recommend this? Can’t say.
  • Is more research into this needed. Yes.

Update a month later.

I tried again with just the spray

One of the bricks got dirty again with fresh green mould.

So I resprayed it and this time it changed colours. From green and grey to orange… and white suds. Interesting.
