How to help reduce water spots...
Which can be a near constant battle made worse by heat (or just your local / sprinkler water) as you are trying to get the Truck or Boat dry "Before" the spots can actually form... Some spots, can get etched very deep onto the clear or gel coats from the Sun on our favorite toys, and become a Royal Pain requiring the use of polishes or even compounds and a buffer to remove! Thus, here are some tips to help control such some, I have not seen on other articles on this subject that may help you.
Now, to help keep spots from forming and short of buying an expensive, very expensive, Water De-ionizer system which many run over $400.00. This list below you might find handy and this is what I do, to help keep such under control, and maybe better stated "Buy you more time to get it dried off before they can develop" are some simple and pretty low cost steps.
Get totally set up for all the cleaning steps, and have everything in place before any water makes it onto the Truck / Boat you are washing. That time you spend to go get say... The Towel, or dig out and plug in the leaf blower, is helping create the issue. Even worse, when working in the Sun or winds that are trying to dry it off faster than you can remove the water. I have seen times that one side was pretty much dry, before I could even get around to the other!
Make sure, you are using a PH balanced Car / Boat soap (not dish soap) AND the correct ratio of soap to water in your wash bucket. More suds is not always better (so yes guys, read the directions on the bottle) since that soap film left behind and now dry, can really create havoc getting it removed.
Naturally, wash and then dry off quickly any side of the Truck or Boat that is in the direct Sun last... Again, it is all about time and how little you have before spots start to form.
Once rinsed off, I have my leaf blower already plugged in setting there ready too blow off the Truck or Boat. This really helps in getting all that water off quickly and around places like the grill, window seals, lug nuts, etc. etc... This also, helps remove it from those same places so it does not run down later on, and create possible problems when trying to apply paint sealants or other protection chemicals.
Then (pending what I am planning to do after blowing the majority of the water off naturally) I use a quality spray detailer on a microfiber towel as a "Drying Aid" which works very well in getting picked up what little water is actually left.
I also use on my water hose line a little RV water filter. Those can help remove chemicals like chlorine and other heavy metals from the water as you use spray your toys down. They are not that expensive, and seem to last quite some time...
7. And of course, there are some other spray chemicals in the market intended on helping get rid of spots after they have formed, and some do help! I have found though, that the use of a quality Graphene paint sealant will generally not allow them to really get etched into the Clear or Gel Coats, and can get wiped right off if you do find some after drying... What is that saying about Prevention is better than the Cure, Amen to that concept!
Now, if you have some other tips you use to help combat spotting due to the hard water conditions in your area. This since some locations are much worse than others... Please, do share them with the rest of the Nation here! She who shall remain nameless, always laughs when I grab the keys and park the Truck and SUV out in the hard rain to rinse off, and then blow dry them after it quits raining. But with the proper paint protection applied, and in good shape, that is a great way to knock all the dust off them without having to break out the hose, etc. etc just to give them a bath!
Hope these tips help, and I think you will find that with a little time and effort in getting the surface be it Clear Coat on your Truck, or the Gel Coat on your hull really clean and protected annually. That your normal post use clean up time, will be much shorter!
