try turtle wax ice products, the liquid polish works great, easy on easy off, can wax whole car in about 30 minutes and the paint is slippery smooth. You can do the whole exterior with it,lenses, trim, no white residue.( minus the rims and tires)The interior works on leather,vinyl, and plastic and doesn't leave that shiny greasy look, even took out spot on the ss seats!!
I've been in the parts business around 11 years now and tried most of the stuff out there, the Ice series is Turtle wax trying to make a comeback and they did a pretty good job

 

the ice is garbage, get yourself some optimum car wax

 

Wow! That's exactly it! Although, in my last house I had an "extra" industrial sized softener left over from a job and put it in my house. Even our toilet water was softened.....LOL!

Oh, I just realized that last statement was left WIDE open for some jokes....Oh Well.....HA!

 

I have used one for 4 years or so got it for the bike,, it does work but you have to change filters often, especially here in AZ.. I like that big filter wonder if I can find just the filter I can build all that framework and such.

I use my Mr.Clean in the filtered water setting and only to rinse the car. It pretty much eliminates any water spotting. I change the filter after about a year. With three cars that's about 10 or 12 washes.

I still chamious my car dry, then clay it once or twice a year. Wax in-between clays with pure carnuba.

Seems to work for me.

 

That is about twice as long as I can make a filter last with the water in AJ. and I also use it mainly for the rinse.

 

I have a buddy who does it semi-pro. Nothing like a hand wash, dry and wax using stuff from Griots!

 

sure, crspotless sells replacement cartridges and even just the resin.
just type in the .com, thats if you want to build your own setup
