Exclusive relic clean up video
Added 2025-01-24 20:00:02 +0000 UTCWitness the clean up process of this British WW2 road sign. It was initially used to indicate roads that were cleared of mines. This sign was later painted over to indicate the presence of the field hospital that was near. I used an oxalic acid solution to clean up this sign and preserved it with boiled linseed oil.
