In our country, wooden fences, as a rule, quickly become unusable, but in the USA they last for 30 years.
And yet Americans don't sand and paint their fences every year.
They use a 19th century Russian remedy, reports the Zen channel “Glass Fairy Tale”.
Americans treat fences with a special product called 30 Second Cleaner.
This super product literally turns any grey piece of wood into yellow in half a minute, revealing the natural colour of the wood.
You will be surprised, but this product was used in Russia for wood restoration back in the 19th century.
This is an aqueous solution of oxalic acid. It is easy to prepare: dissolve a kilogram of oxalic acid in 10 liters of warm water.
