We recently had our deck re-stained. The guys that did it stripped back the old stain with a chemical stripper, and power washer. As a consequence the old stain has splattered onto some of our external walls (some textured/rendered, some painted plaster), metal deck joists, and in one case - under our front door and onto an internal wall. As it was a hot day, it has now dried and power washing is not taking it off. On the smooth surfaces, the splatter appears to be superficial and can be (painstakingly) scratched off e.g. with a paint scraper. On the textured surfaces it’s trickier. I’m looking for a faster solution to cleaning it up and wondering if something like turps might do the trick?
