Does it really work? Are you actually spot free? Whats wrong with regular rinse setting without pulling the wand trigger? Is there anyone in this community with car wash knowlege? What are your thoughts?
The wifes car is now crudless, yet this is the spot free rinse result. My foil hat says its a ploy to get another 2 minutes of money.

Spot Free Rinse is Fake News.

I would assume that spot-free rinse includes an additive akin to Jet-Dri in dishwashers.
I would also suspect that diligence in keeping the drying agent tank topped up is nearly nonexistent.

I am highly suspect given the tendency for car washes to give a shit and actually put the correct additive in the cor
rect tank.
I only go to car washes for the warm water and to remove the big chunks in the winter time.

I understood the “spot free rinse” to be a filtered or treated water that wouldn’t leave behind water spots when it dries.
I usually use it if I have some time left.
But does it work? I dunno... Whenever I care about keeping the car super clean, I’ll dry it off with a towel in the parking lot, and if I don’t, I’ll just drive off and probably get dust in the water before it dries.

I’ve drunk the spot free kool-aid.
My local wash is decent, and the spot free is something like QEW added to the spray- by the time I’m back at the house everything has beaded away.

Oh hey, my talents are needed! I develop car wash chemicals for a living.
Spot free rinse usually adds a little bit of drying agent to the stream. Usually it’s a thin mineral seal oil that’s emulsified in the water. This helps repel the water off the car as even filtered water will pick up stuff from the air and leave a spot behind if it doesn’t roll off the car.
It’s not too useful in a bay wash like the one you’re in, and those places are notorious for being slow to replace that when it’s empty. Especially when compared to the presoak and the main soaps.

So that’s the “sauce” in your username.

Lots of car washes
use a filtering system to remove the hard minerals from the water and maybe an additive
. Does it really work? Is it worth the money? Yes and no.
The effectiveness
of the system depends on how well it’s been maintained. I usually don’t use it at a car wash... Most of the time, soap or other contaminates find their way into the “
spot-free” water.
I work at a dealership and we have a brand new system that filters the water and holds it in tank that can then be dispensed with a high pressure nozzle. I do not have to dry my car after using it. No detail spray. Nothing. It’s fantastic.

Thi s has been my experience. The coin wash near me hasn’t refilled the drying agent in over 5 years. I’m lucky if they even have wash soap half the time.

its just (as I understand) deionized water, I would say it works but its not the same as drying it properly.

Foam brush?! NOOOOOOOOOOoooooooo.........
I can’t bring myself to use those things. No telling where they’ve been.
If I’m serious about getting my car clean at a wash bay, I go at an off-peak time and take along a clean microfiber. I use the wash soap for whatever the minimum time is, and get my towel nice and soaked with soapy water before the time runs out. Then hand wash top to bottom with the towel, then another round of wash soap and then rinse.
My truck is actually pretty dirty right now - it’s definitely due a good wash.
Think the wax actually does much?

Just get 2

My inside detailer dies a bit each time but I keep telling myself
I’ve got an unswirler ready to go in the spring;
Brush gets sprayed out before it touches paint, and it’s top down, wheels last.. S elf-wash only gets done either a) appres rally/offroad, or b) after winter road trip to get highway salt off.

I work as the technician for a car wash, our system uses a reverse osmosis filtration/membrane system which is after the soft water system for the spot free. We have very hard water in our area and this type of system works quite well. It does make a huge difference if it is maintained.

there’s definitely a difference here in AZ.
from my experience, the spot free rinse is water that has been softened. I thought it was bullshit and rinsed with the high pressure wash and it left horrible water marks. My guess is that the spot free has the calcium and minerals removed from the water.

I prefer to just wash normally, then hand dry it afterwards. No need for “spot free” (which always left me with worse spots than normal rinse), no need for the extra money to do so.

While I can’t speak to the validity of all car washes, a good car wash will at least have an RO (Reverse Osmosis), or better yet ion exchange to deionize the water.
Long story short, the lower the total dissolved solids (TDS), the less contaminents that can leave water spots on your car. If you have hard water and let it dry, it’s the solids (calcium, magnesium, among others) that are left behind which show up as water spots. An RO will reduce that significantly, and a good DI system will remove all of the TDS. Then you could theoretically wash your car, rinse with DI water, and not even touch it and have no water spots since there are no dissolved solids to leave behind. But most car washes won’t go to that extreme, so it simply will make the water better quality and minimize the amount of water spots, but you’ll still want to dry properly to eliminate the spots.

There’s a difference in the spot-free rinse at my local self-service wash. I usually have to wait at least 15 seconds for the selector for selector to take effect, so I’ve taken to checking the look/feel of whatever’s coming out of the sprayer while I wait. The spot-free stuff has a slightly tacky feel to it when I rub it between my fingers, and the water on the car beads off a little more effectively. Fewer spots will be left over afterwards, but those that do seem to be more noticeable (especially on black). Hand drying is much
better and removes the need
, but if I’m feeling lazy or it’s mid-winter, I’ll just hit the spot-free for 60-90 seconds and then go for a quick blast down the nearby interstate to air dry.

FFrom the guy that supplied the chemicals to us at the car wash I worked at as a yute. Use the wax to rinse. There isn't anything much to the spot free. The wax will dry without spotting. Been doing it for years, so far no issues.
