Why It Happens
Why the smell comes back on hot, humid days
When urine dries, it leaves behind uric acid crystals that are insoluble in water — a normal cleaning, even a thorough one, doesn't dissolve them.
Those crystals sit dormant in the carpet fiber and seat foam until humidity — South Florida weather, a spilled drink, even body heat on a hot seat — reactivates them and releases ammonia gas again. That's the classic "old urine" smell returning weeks later, even though the seat looks perfectly clean.
Baking soda absorbs moisture on the surface, but it doesn't break the crystal structure underneath, so it's a temporary fix at best. This applies the same way whether the source was a pet accident or a child.

Why baking soda and carpet shampoo don't fix it
Baking soda
Absorbs surface moisture and some odor short-term, but does nothing to the uric acid crystals already bonded to the carpet fiber and seat foam.
Carpet shampoo
Cleans the visible surface but can't dissolve uric acid crystals — they're insoluble in water, so shampooing alone leaves the source intact.
What actually works
Enzyme treatment formulated to break down uric acid and protein, followed by peroxide oxidation and professional ozone that reaches crystals deep in the foam — not just water and soap.
The Real Process
6 steps. Every urine odor job.
The exact sequence DShine uses — same products, same order, every time. $349 flat, travel included.
Step 1 — Enzyme Treatment
P&S Terminator
A broad-spectrum enzyme package that breaks down organic protein, fat, and starch-based contamination at the molecular level, so it can't re-volatilize — meaning it can't release odor again later. This goes first because it's the only product in the process that breaks the organic bond itself, rather than just lifting surface residue. This step is the one that actually matters for urine: dried urine leaves uric acid crystals that are insoluble in water, and only an enzymatic breakdown — not baking soda, not a water-based cleaner — dissolves the crystal structure itself, so it can't reactivate with humidity later.
Step 2 — Citrus Degreaser
P&S Carpet Bomber
A citrus-based degreaser and cleaner that cuts through grease, oils, and general grime bonded to carpet and upholstery fibers — loosening what the enzyme treatment didn't target, and prepping the material for extraction.
Step 3 — P&S Finisher
Peroxide Treatment
A mild oxidizer (P&S Finisher Peroxide Treatment) breaks down remaining organic residue and odor-causing compounds left after the enzyme and degreaser stages. It breaks down into oxygen and water — no chemical residue left behind.
Step 4 — Deep Clean
Meguiar's APC + Steam
Meguiar's All Purpose Cleaner foams into every interior surface — fabric, vinyl, leather, headliner, door panels — while steam heat activates the cleaner and drives it into the fibers across the whole cabin, not just the odor zone.
Step 5 — Ozone (O3)
Professional Ozone Treatment
With surfaces clean and residue removed, the final two steps target what's left in the air and ductwork. The vehicle is sealed with a professional ozone generator for 2–4 hours. Ozone oxidizes bacteria and volatile organic compounds at the molecular level in places physical cleaning can't reach — seat foam, headliner, HVAC ductwork. Any ammonia gas left over from broken-down uric acid gets neutralized here too. Not a masking fragrance. Safe to drive after 30–60 minutes of airing out.
Step 6 — Final Pass
Odor Eliminator Mist
A final one-time-use Meguiar's Whole Car Air Re-Fresher Odor Eliminator Mist is released with the A/C on high and recirculation on. Doors stay closed 10–15 minutes so the mist reaches the ventilation ducts and headliner, then the vehicle airs out 10–15 minutes. It eliminates remaining odor at a molecular level as a final pass — not just fragrance.
