@ : I suspect that the field service representative who announced himself following your notice will evaluate the aspect of "cleaning with a high-pressure cleaner" for himself and interpret it in the interest of his company. If that should be the case, a "sprucing up" (as a solution) could consist of sanding the surfaces, depending on the size of the depressions possibly preparing them with a scratch filler based on synthetic resin and then resealing them with a pigmented (or after the addition of flakes) UV-resistant PU resin. Practically, that would definitely work and would also last for the next few years. However, I would soon refrain from a "KÄRCHER" cleaning and rather devote myself to a basic cleaning with a scrubber and cleaning cloth. The scrubber should have soft bristles and the basic cleaner (additive to the cleaning solution) should be set alkaline. --------------- Regards: KlaRa
