Hi everyone,

During my visit to AutoZone yesterday, I stumbled upon an undercarriage pressure washing attachment for $50. I had never considered using such a tool before, but it got me thinking. Do y'all think this Is this a worthy investment?

For some added context:
  1. I live in Indianapolis and thus, have some winter-related reasons (dirty snow, salt, etc.) for washing the undercarriage. However, I wouldn't be washing my car at home during those months...I would be at the self-serve "auto spa" (and thus, obviously not using the attachment).
  2. I try to wash the car 1-2 times a month. The car is my daily driver, but I do not do much commuting b/c I work from home. I do, however, look for (or make up) any excuse to drive her...because obviously. I do not track my car.
  3. My father was someone who washed his car every weekend (here in Indy) religiously, but never invested in any kind of pressure washer, let alone an undercarriage-specific one. His cars were always in excellent (yes, legit excellent) condition. This also has me thinking the attachment may not be worth it.
I'm currently leaning NO, but I wanted some feedback from you all, esp. if you feel strongly YES or NO. Thank you in advance, and I hope everyone is enjoying their respective summers.

Ive never considered this, but might be worth the investment. I live in northern Illinois and will get one of these for next winter to wash the salt off from underneath.

If you are willing and able to get on the ground, I don’t think that this gizmo will do much that you can't do with just the hose. I live in NC where frozen precipitation and salt are not season-long events. Often, we get rain within a week of the salt, so a good drive in the rain gets rid of the undercarriage salt. Otherwise, a car wash with the hand-held high pressure wands do a good job.

I live in Canada, so I use an undercarriage spray attachment year round.

That way I get to keep the salt off as much as possible, and I get to stay dry because the attachment is doing all of the work.
