CARPRO IronX 1 Gallon

Description
The CARPRO IronX 1 Gallon is the CARPRO IronX iron remover in bulk format, for people who decontaminate cars constantly — detailing businesses, coating installers, and multi-car households. You get the same purple-bleeding chemistry as the famous 17oz spray, in a refill jug that seriously lowers your per-job cost.
The Best Iron Remover for Car Paint, Priced for Volume
At $107.99 for 128 ounces, the gallon works out to roughly 84 cents per ounce versus about $1.18 for the 500ml bottle. The formula itself is unchanged: pH-neutral, safe on every finish, dissolving embedded brake dust and rail dust from paint, wheels, glass, and chrome while shifting purple to show its progress. It's the exact product detailers made the industry benchmark — just bought the smart way.
Working From the Gallon
- Decant into a chemical-resistant spray bottle; the jug is a refill, not an applicator.
- Apply to washed, rinsed surfaces so it attacks embedded particles rather than road film.
- Give it time to react — purple runoff tells you where iron was hiding.
- Rinse completely, then move on to claying, polishing, or coating prep.
Gallon, Spray, or Paste?
If you decon one car a couple of times a year, the 500ml spray makes more sense. The gallon earns its keep once you're refilling that bottle monthly — shops, mobile detailers, fleet work. Pair it with IronX Paste for baked-on wheel contamination, or keep the Lemon Scent 500ml in rotation for indoor jobs.
Is the gallon the same formula as the 500ml IronX?
Identical. You're buying the exact same color-changing, pH-neutral decon chemistry, packaged as a refill instead of a ready-to-spray bottle.
I searched for a 5-liter iron remover — is this close?
The gallon (just under four liters) is the largest IronX format in our catalog, and it refills a standard sprayer many times over — it hits the same bulk-buying goal a 5L jug would.
How should I store it between details?
Keep the jug sealed, out of direct sun, and label any secondary bottles you fill from it — standard practice for any decon chemical.

Pro Detailer Tips
Patch Test First
Before applying any new product to a full panel, test on a small hidden area first — especially on older paint, vinyl wraps, or exotic finishes.
Read the SDS Sheet
Every professional detailing product has a Safety Data Sheet (SDS). Review it before first use to understand proper handling, dilution limits, and safety precautions.
Store Properly
Keep products in a cool, dry location away from direct sunlight and freezing temperatures. Extreme heat or cold can degrade chemistry and shorten shelf life.
