From Clay Carson of Act One on September 17, 2020:
I'd agree that chemical weapons are the way to go. But protecting surrounding surfaces is often a bigger issue than the core job. Despite what chemical vendors say, it may take multiple applications and may be much slower than claimed. It's literally impossible in many cases to avoid damaging building components directly below the masonry. Legal implications and full disclosure in advance, in writing all the way up the food chain to property owners is a bare minimum. If done correctly, the job may need to include repairs of what the chemicals damage. Walking away from a job is also an unmentioned but realistic option.

From Richard Devick of UCI PAINTS on September 11, 2020:
I’ve used a caustic hell or paste that gets cover with a wax type paper. Allow to dwell a day or longer, then remove paper (carefully) and power wash surface(using protective equipment) another application my be required. and a hot water pressure cleaning my be used.

From Rod Rodriguez of Rbrothers painting on September 10, 2020:
I would use Detrecks 606 let It set For 4-8 hrs and pressure wash don’t forget to protect adjacent surfaces, and contain waste.
