I live in SoCal and for the last wk or more I have not washed the car. I feel bad for leaving the dirt on the car for so long cuz I feel like its corroding the clear coat. The question that I have is that is it worth to at least hose down the car? I have not been able to was it because its been raining daily for the last couple of days and otherwise it has been cold. So should I at least hose it down? There is a self serve car wash near by with desalinized water, should I at least do that.

 

you could water down but dont do it with high pressure

 

Why not? I usualy water my car, let the water sit, wash down with water again and then usualy high pressure water. Is that bad?

 

if you do with high pressure you could damage the clear coat

as long as its not one of those self car wach (air pressure water gun)

 

really? where do you have proof of high pressure water damaging the clear coat? i think high pressure water is okay to use...

there you go

 

its been raining in socal didnt that clean your car? i know my car looks clean

 

I disagree, a pressure washer (low setting) should be fine on the car. You'd need a pretty high PSI to do damage on your car, and most car wash places should fall below that threshold. As DiamondG said in that other thread, anything below 1200 PSI should be fine (I saw a website recommending 700-1000).

Of course, there are those 2000+ PSI ones that people use on heavy duty equipment...I definitely wouldn't recommend using something like that.

 

No. Rain creates an adhesive surface for dirt and grime to cling on to. On top of that dirt from water puddles and blasted on the car.

 

I dont know how many PSI my gardening hose has buts it well below 1200. The ones at self serve car washes is even less than that. The desalinzied water pump they have a fairly low pressure.

 

My car looks like azz too right now... I hate it... Lol...

Gonna wash it toniight tho...

 

Well if a HP wand damages the clear I hope non of us drive a dirty car in the rain on the hi-way.

 

No kidding. If thats the case, I'm scared to wash the inches of salt off of my coupe when it warms up. The entire car is white, and its been sub zero temps for almost the past month, so its built up quite a bit. We'll see what it looks like when I get a chance to clean it up. (I have a feeling it will be going to a professional detailer for a detail...)

 

Me too...

 

More rains coming this weekend
