That is according to Mike Pennington, director of training at Meguiar's, who stated that many people still use washing up liquid and tea towels on their vehicles believing that these will do a good enough job. Hot Rod reports.
However, nothing could be further from the truth, as the chemicals in the soap coupled with the rough nature of dish cloths mean that the paint is being subjected to a lot of abuse.
Instead, drivers need to invest in the "right products" the expert said.
"Unfortunately, many people still use dishwashing detergent and poor quality towelling to wash and dry their car, not realising that the detergent is so aggressive that it can actually begin to dry out the paint … while the rough and unfriendly towels cause minute scratches and swirls," Mr Pennington told the blog.
Ricochet's Rapid Detail made a similar point recently, stating that swirl marks are likely to be the result of poor washing technique.
