Undercoating locks in whatever is on the surface. If salt or brine is still present, you’re sealing corrosion into the metal. Proper prep with Salts Gone® ensures you’re starting with a neutralized, salt-free surface so the undercoating bonds correctly and protects long-term.

• Remove any loose rust or flaking material.
• Apply Salts Gone® (Hose End or Pump Sprayer) to neutralize salts and brine.
• Rinse thoroughly and let the surface dry.
• Once completely dry, you’re ready to undercoat.

No. Water alone can push salts deeper into seams and crevices. Salts Gone® chemically neutralizes chlorides on contact, eliminating the problem instead of spreading it around.

No. Salts Gone® does not emulsify oils, waxes, or protective coatings. That means it’s safe to use even on vehicles that already have a lanolin or oil-based undercoating.

Yes. Salt and brine often hide in seams, cracks, and under existing rust where you can’t see them. Neutralizing chlorides is the only way to ensure they’re not trapped under your coating.

A good rule of thumb: if the surface can safely get wet, it’s safe for Salts Gone®.

Use it without worry on:

Metals, glass, paint, ceramic coatings, wax, vinyl wraps, carpets, etc.

Salts Gone is meant to be used on an "as needed" basis. For maximum protection, apply Salts Gone® after each exposure to salt or brine. At minimum, we recommend once a week during heavy winter treatment periods. Depending on how often you drive and local conditions, you may need to treat more frequently — or get by with less.

Most customers cut their cleanup time by 60–80%. What used to take 20–30 minutes now takes just 5–10 minutes with Salts Gone®. Spray it on, rinse it off, no scrubbing required.

For simple salt removal, no scrubbing is needed. Just spray and rinse.
For heavy dirt or grime, a quick brush or sponge may help activate the built-in surfactants.

Usually not. Salts Gone® contains surfactants (soap), so most people replace their car wash with it. If there is lots of dirt/grime, you'll want to use a brush or some form of agitation to get it off.

One 32 oz Hose End Sprayer produces up to 25 gallons of ready-to-use solution. That's enough to treat a 24-foot bay boat around 4–6 times or a pickup truck around 5–7 times, depending on coverage and conditions.

Yes, Salts Gone® is eco-friendly, biodegradable, and non-hazardous.

Not if you're using our Hose End Sprayer. It does the mixing for you.
If you're using a pump sprayer or injector, dilute at a 1:100 ratio (that’s 1.28 oz per gallon of water).

Salts Gone® is not designed to remove rust. However, many users report that soaking lightly rusted parts in undiluted concentrate can help lift surface rust thanks to the corrosion inhibitors.
