The worst monsoon flooding in decades has isolated millions of people across Bangladesh with Sylhet being one of the worst hit areas.
The two hardest-hit subdistricts of Sylhet are Companyganj and Gowainghat.
Lalmonirhat, Kurigram, Nilphamari and Rangpur districts in northern Bangladesh have also been badly hit.
This disaster has come only a month an after unprecedented pre-monsoon flood hit northeastern India and Bangladesh causing 70% of Sylhet to be under water.
All proceeds will go to families affected by the floods.
The car-wash event takes place this Sunday (3 July) between 11am and 9pm at Ride and Shine Elite Valeting,
Unit B Ellen Street, Oldham, OL9 6QR.
