When you rinse with hard water, you could be dousing your vehicle with hard mineral deposits. The only way to prevent hard water deposits is with a water softener.
Sediment is rust or sand that is inside water pipes. A broken water main miles and miles away can allow sand to enter your water supply. Likewise, a little rust anywhere along the water line can flake off into the water. This is why your household faucets have filters. Needless to say, sand and rust hitting your paint finish should be avoided. A filter will remove fine sediment and protect your vehicle as you wash it.
A one-step, in-line filter will remove one of these problems, but what if your water has both sediment and hard water? Well water almost certainly contains sediment and minerals because it is not filtered through a water treatment plant. But even city water can contain both sediment and hard water. That’s because many water treatment plants add lime to the water to raise the pH in order to spur the chemical process that removes debris from the water. Lime adds to hard water.
Most of us need a two-part filtration system that both removes sediment and softens the water to ensure that the water coming out of the hose is truly clean. This helps ensure you’re washing your vehicle in clean, soft water.

If your wheels are CC and you have not had problems in the past you should be fine. Do not let IronX dry on the wheels.

Rinsing first will help remove any loose dirt or debris. It should not effect using the IronX or IronX snow soap.

I've had very little streaking issues with the latest Reload formula. Use it in the shade and you should be fine.
