- 1/ Wait for it to rain
- 2/ Put on your swimsuit, and a rash guard if it's a bit chilly
- 3/ Fill a bucket of water with an eco-friendly product (washing-up liquid works well) (eco-friendly is better because it goes straight into the gutter)
- 4/ Head out into the street in your swimsuit with your bucket and sponge
- 5/ Wash your car
- 6/ Get strange looks from passers-by
- Bonus/ What to do if it's stopped raining in the meantime? Use the gutter water to rinse the car
- 7/ Have a clean car
And there you go, a cheap and completely eco-friendly tip since it doesn't use any water!
