As a point of interest, it should be noted that the frequent sulphuric acid rain showers on Venus never reach the surface of the planet.

Falling from the cloud layer between 48 and 58 km, these acid droplets will encounter such high temperatures at 30 km that they evaporate.

Sulphuric acid evaporates at about 300°C ; decomposing into water and sulphur dioxide. These gases then rise to feed the clouds on Venus. Contrary to what one might think, acid rain on Venus is therefore not a major cause of surface erosion.
