For cleaning your bike I have the answer...... go to your local hardware store and buy one of these (pic attached).
then go to your local supermarket and buy some distilled water.

After doing your regular wash spray your bike down with the Flo-master with distilled water and FM (fukkking magic) NO WATER SPOTS!

Oh! Don't forget to blow dry with leaf blower(or whatever) after rinse.

Final step PLEDGE

 

Ok, I'll bite, If you are going to use Pledge anyway why would the water spots matter?

 

Great idea! I might have to try this.

 

Because you can't get everything with the pledge. I washed yesterday and didn't need to wipe anything down b/c there were no spots when I was done, distilled water works great

 

Btw any of those pumps will work I am not trying to promote any particular brand

 

I have no doubt that the distilled water does a good job and does not leave spots. Glad you found something that you like.

 

Back when I lived in MI we had well water. I had three black cars, after washing them I would do a rinse using rain water I collected in a plastic 55Gal. drum. Had a boat bilge pump hooked to it. Never had problems with water spots. In fact many times people would ask if I just waxed them.

 

I almost cried when I could no longer could get cartridges for the Mr Clean car Wash System, Then I remembered what I have learned on the forum "Cryings Gay" I found this at Costco http://crspotless.com/ it works better than the Mr clean system and lasts a long time between refills. Kinda pricey up front but cheaper than the Mr Clean cartridges in the long run

 

I have water softner in the house so I just fill a tank sprayer with it and use that.
