The sponge does hold a lot of liquid/suds which is a good characteristic when it comes to washing your vehicle but underneath this helpful first impression is a much darker trait….. It’s shallow pores.
The exterior of the sponge is thousands of tiny pore-like openings, the issue with the sponge is how shallow these are. They are often smaller than a piece of grit. This results in any dirt/grime that you may wipe over with your sponge getting ‘held’ in these pores o the outer surface, this results in the dirt/grime being literally dragged and rubbed over your paint work = swirls and scratches.
We have a regular customer who bought a brand new black Honda civic ($33,000 roughly), went home and washed it with a sponge. The paint already looked HORRENDOUS, especially in the sun…
So now your paint is scratched to hell…. Cost number 1 - You can get it fixed via a lengthy paint correction process which will run you anywhere from $400-$800 to get it back to perfect. Hopefully you learn your lesson and don’t use the sponge again!
Your car’s exterior is the first thing your potential buyer will see and gives a great insight into how well the car has been maintained and how knowledgeable the owner has been. Here’s the hot tip, if your paint is scratched to hell, it definitely isn’t the best first impression!
