Beaches run by Chichester District Council have reopened following a clean up to clear the caster oil which was washed up on them.
Clean up teams from the council have been busy clearing East Wittering and Bracklesham Bay beaches of the yellow foam-like substance.
It is not yet known where the castor oil has come from and this is currently being investigated. The caster oil was washed up on beaches on Tuesday (January 11).
The council decided to temporarily close the affected beaches in the district. Hayling Island and West Wittering beaches were also temporarily closed.
