The effect of tar on Wudu'

Q: What is the effect of tar on Wudu' (ablution) performed to offer Salah (Prayer). Tar sticks to the hands for a long time exceeding a week, and when performing Wudu', it mixes with the water of Wudu'? Please advise. Best regards.

A: Tar should be removed from the parts of the body that must be washed in Wudu' (ablution), because its high density prevents water from reaching the skin.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
