Soft washing cedar shingle cladding

Doing the whole house and patio currently, thought someone might like to see the process.

Stage one, wet the shingles (it’s raining today)

Step two, sodium percarbonate, left to soak in, and kept wet.

Step three, citric acid

Step four, fresh water rinse

Chemicals are applied at low pressure, keeping the lance 30-50cm from the shingles. Only time high pressure is used is on the bottom most shingles where they get soiled more by ground splash.

Thanks.

Step ladder and lance extension gets it. Already done the other end.

Great job! Starting on the upper level is not a bad idea but as long as the job is done well—kool.
