“No Bleach!” The customer demands. This job is actually for a painter who sends me lots of business, which is why I cannot heed @Innocentbystander 's warning to run away from this job. (I heard your voice in my head as I drove up to this beachhouse)
My job is to prepare the shingles for staining, but also to clean the soffit. Advanced colonies of algae grow in a few areas, and some of this soffit is 35+ feet up.Most of the soffit is just covered with salt and sand, but there’s an area 40’ up where the dryer vent has a lot of black around it. What cleaner will be most effective in this assault that isn’t SH. ALSO, decks and windows may be added on if we’re effective with the siding and soffit: the decks are either IPAY or teak, and I’m thinking Sodium Percarbonate at 25% solution pretreat, dwell for 5 minutes and pressure wash.
What does my braintrust think? This is definitely NOT the standard job.
