Washing your car using old, worn out t-shirts or other pieces of clothing might be the cheapest way to do so, but it may have some negative effects on your paint job.
Sponges and wash mitts are the best options because they are specifically made to have soft surfaces that are gentle on paint, and also absorb a lot of soapy water so that you can conveniently cover a larger surface area after every bucket dip.
