So I have been detailing this guys cars all year long and he just tells me yesterday he used to own his own mobile wash. He used to do like UPS trucks. He said he used a hot water pressure washer which just melted any dirt and grim of in a heart beat and he said he used a spot free rinse additive that left the trucks looking great-no drying. I asked if he remembered what it was called but he couldn't recall.

I started looking around and came up with this. Spot free rinse additive that reduces drying time Now I've heard that some of the chemicals leave a film but I know for myself some don't.

Anyone have any experience with a spot free additive- Not looking for the CR spot free or filters.
 
There is no such thing as an additive that will give you SPOT free if you dont dry..the only way to achive that is to be using water with 0TDS or atleast with lower then 10..Only way your going to get that is by using Distilled, Buying a RO unit, or one of the spotless units at Autogeek.
 
As the description says in your link, it increases the sheeting action so more water runs off...like the rinse aid stuff you buy for your dishwasher or the stuff in the Mr. Clean AutoDry thing...it's a polymer that helps the water to sheet off. Just bear in mind that this guy was washing UPS trucks...with mostly vertical surfaces and who really cared how good they looked when they were done? Also, most car washes include this type of rinse agent, which is why some tend to kill your beading temporarily.

While traveling I ran my car through a touchless wash that claimed spot free. It did kill the beading on my OC finish until the next wash.

I was referring to the car wash soaps that WE use. IIRC polymers are added to car wash for multiple reasons--here's a quote from the Meg's Gold Class description here on Autogeek: "The secret blend of conditioners nourish the surface and acts to lubricate the washing area, preventing the abrading effects caused by friction. The sleek, smooth surface literally sheets off water – a Meguiar’s technology caveat – causing the vehicle to actually dry faster and clearer!"

Of course, I always found GC to be one of the streakier washes if it started to dry on the car before you got to rinse it thoroughly--presumably because of the high polymer content.
 
I have incredibly hard water where i live. I have heard of people sheeting the water off with the hose, then before drying spraying the wet car down with a light mist of detail spray.

Does anyone do this? And does it help with water spots? Black car + crazy hard water = evil.

There's a number of products meant to aid drying and prevent spotting--DG AquaWax, EO Wax-As-You-Dry (WAUD), OCW can be used when drying, or this: Dodo Juice Time To Dry Drying Detailer,Drying Detailer, dodo juice detailer
 
Although I've never tried adding this to my car wash...I know it does prevent water spotting on just about anything else I've tried it on....WD-40 (its paint safe as well because I use it to remove tar, asphalt, road stripe paint, even bugs....it's main ingredient is fish oil.

Check out their web site some time...its right up there with duct tape in terms of uses.

Interesting. The coin drop car wash that I use for pressure washing my mats had spot free rinse as one of the selections. Wonder how that works.

I suspect more like the rinse aid in your dishwasher than like a CRSpotless.
 
Another vote for "Wax As You Dry."

I don't use it all the time, but it really helps make drying in warm (hot) weather much less likely to water spot.

Oh, it smells good also (does that count?).

So would it be a good idea to add a dishwasher rinsing agent to the shampoo for washing cars? If the only side effect is temporarilly preventing beading, I will be polishing or sealing or waxing the car after the wash anyway so that is not an issue. Preventing water spots seems a very nice thing to add.
 
Ok I see these topic pop up so many times and it makes ZERO sense to me. nothing you add to your wash bucket is going to aid in anyway a spot free rinse. I dont care if you used Distilled water. Because when you rinse off the car with the hose that is NOT perfectly clean water or has anything to prevent spots unless its hooked up to a CR unit or something like it. You just threw hard water onto the car rinsing away all the spot free water solution that was on the car. So NOTHING you add to a wash bucket is going to make a bit of a difference once you take the hose for a final rinse.
 
Makes sense... I wish there was a way to get soft water out of the hose...

Maybe if I rinsed with a power washer using the rinsing agent into the foaming bottle?
 
or you could get a 3 gallon pack at a grocery store of Distilled water. and after your final rinse flooding of car. take the 3 gallons and pour over the car of perfectly clean water. This still wont mean your gonna get 100% spot free but will be a huge help and only cost about $2.50 for the 3 gallons
