Brick Cleaning
Status Check:
Hi,
Got a customer with a lovely victorian house. I clean her windows and pressure wash her drive regularly, she has asked if I could clean her walls using my pressure washer which is a Honda GX390. I have done a test patch and it does come up well but I feel that this PW is not the best machine to use for this job. Just seems to be a bit harsh if you know what I mean.
What do you guys use? Was thinking of hiring a Doff or Thermatech but fear that it would take weeks to complete?
chris scott:
Do you have a picture of the house?
chris scott:
Hydrofluoric acid . Not too strong else you will burn the brick.

Mmmmmm....just googled it. Sounds like scary stuff! :-) Is this different to ordinary brick acid?
chris scott:
Two different acids
Hydrofluoric acid (The one you need for that job) You should also buy calcium gluconate cream.
Hydrochloric acid (Brick acid)
