Step 01
Pick a surface to test.
Decide what to test first. Painted trim. A vintage plate. A baby bottle. The windowsill where dust collects. Old, hand-painted, or imported is a good place to start. The surface must be dry.
-
Step 02
Apply the liquid to the surface and shine the light.
A spray or a drop, then the included 365 nm UV light. Green glow = lead. No glow = clean. Real time, with your own eyes. No app, no lab, no waiting.
What customers found in their homes.
Media sent in by real FluoroSpec users. Same glow, different places. The bright green is lead reacting in real time under UV.

What you can test.
One spray or one drop, then 30 seconds under UV. These are the five vectors where lead most often shows up in a household.
Most importantly.
33 million US homes still contain lead paint.
And 18 million of those have an active lead hazard.
The CDC has lowered the safe blood-lead threshold five times since 1970, and it keeps moving down. The dust on a windowsill is invisible. Standard hardware-store swabs were built to test paint chips, not the dust at the threshold of harm.

Before you buy.
How accurate is it?
FluoroSpec uses the same fluorescence chemistry that detects lead at parts-per-million levels in lab settings. It is approved for commercial sale by EPA under TSCA Sec 5 LVE L-25-0206 and detects below the HUD floor-dust standard of 10 µg per square foot.
What if it glows on something safe?
False positives are rare and usually trace to a small set of materials (some uranium glass, certain mineral pigments). The reference card lists them. When in doubt, request the free soil-style XRF mail-in for a quantitative reading.
How is this different from a hardware-store swab?
Rhodizonate swabs need a paint chip with raw paint exposed. The actual exposure path is dust at the threshold of harm. FluoroSpec reads the dust directly. The swab is asking a different, narrower question.
Is the chemistry safe for kids and pets?
The reagent is non-toxic at the dilutions used and wipes off most surfaces with water. The kit ships with full handling instructions. Keep the bottle out of reach the same way you would any household cleaner.
What does the soil test cover?
Lead, cadmium, arsenic, mercury, chromium, and 15+ other metals quantified in parts per million on a Niton XL5 Plus XRF analyzer. You get a written report by email, usually within a week.
Money-back guarantee?
30 days, unconditional. Return it (or don’t) for a full refund for any reason. No restocking fees, no questions asked.

Hand-me-down baby bottle from 1982. The graphics lit up. My toddler had been drinking from it.

Sprayed the windowsill in our 1948 house. The whole trim line lit up green. Called the abatement people the next day.
Marisa K., Portland OR
★★★★★
Found three mugs in my cabinet that lit up under the drip. Goodwill rim, vintage Fiestaware, and one I bought in Mexico. Tossed all three.
Dan R., Austin TX
★★★★★
My toddler had elevated blood lead. The kit found the source in an afternoon. Painted dresser in her room, the previous owner had stripped and repainted with what turned out to be old leaded paint underneath.
Jess T., Cleveland OH
★★★★★
Sent in a soil sample from our garden bed. Got a full XRF report back with lead at 380 ppm. Built a raised bed instead.
Kira H., Brooklyn NY
★★★★★
As a home inspector this thing is in my truck every day. Faster than a swab and it actually catches dust contamination.
Marcus L., licensed inspector

Tested the turmeric I brought back from a trip. Glowed. Found out later that brand had been recalled in two countries.
