Spray Bottle Kit
Mist a wall, a baseboard, a windowsill. Shine the light. If it glows green, it is lead. About 170 sprays, or 500 with the included ring.

What is in the box
01
A fine mist that covers area fast. Roughly 170 full sprays out of the box.
02
Snaps on and takes the same bottle to about 500 sprays without losing sensitivity.
03
Tuned for this reagent and in the box. The glow only reads true under the right light.
04
A non-toxic card that shows you exactly what a real lead-positive glow looks like, so you are never guessing.
What the spray is best at
How it works
A light, even spray over the spot you want to check. You do not need much.
Any true 365 nm light works. The kit includes one. Give it a few seconds.
A bright green glow is a positive. No glow, no lead at the surface you tested.
The honest part
It is built for area. For dishes, mugs, glaze lines, painted toys and small items you can hold, you want the drip tip, it is precise and goes much further per bottle. Same liquid in both, so they refill each other. When you check out you can add the drip-tip bottle for $16.
Your problem is my problem
I built this because I was tired of watching kids get poisoned by things nobody thought to check. Buy the kit, and if you ever hit something you cannot read, mail me a sample and I will run it on my XRF for free. There is never a charge for follow-up. I learn from every weird case, and it makes the next version better.

Quick FAQ
Around 170 full sprays out of the box, or about 500 once you snap on the included extender ring.
A FluoroSpec reagent. It binds to lead and fluoresces bright green under 365 nm UV light. The reference card is non-toxic.
You need a true 365 nm light. The kit includes one tuned for this. Most cheap "UV" flashlights are the wrong wavelength and will not read correctly.
Yes, used as directed. It is a light mist, not a fog. Spray the surface, read the glow, wipe it down. Open a window if you are doing a whole room.
Yes. Refills are sold separately, and because the spray and drip share the same liquid they top each other off.
A light mist. The light. A straight answer in about thirty seconds.
Get the spray kit · $50 →the number that matters
The FDA Interim Reference Level is 2.2 µg/day for a child, 8.8 µg/day for an adult. That’s the daily intake your body can clear without measurable harm.
A single painted plate at the rim can leach enough lead in a meal to put a 2-year-old over the line. One dusty windowsill in a pre-1978 home can do it in a week. One solder joint in a kitchen faucet can do it every glass of water.
ppb on a lab report is concentration. µg/day is dose. Concentration tells you lead is present. Dose tells you whether the source matters. This kit finds the source.

If all this did was find the windowsill dust that was putting your kid over 2.2 µg/day, would it be worth it?

“Spray bottle found dust we missed.”
Marc · Mar 2026 · verified · judge.me
XRF'd the house last year, clean-ish. Sprayed the window trough and the dust lit up bright green. The XRF reads the paint, the spray reads the dust that blew off the paint. Both matter.
“75-year-old house, finally a straight answer.”
Andrew · Jun 2025 · verified · amazon
I've tried every lead test on the market over 20 years. This method blows them all away. Results in seconds, no false positives, and I can trust what I'm seeing.
“Lead was only in one specific area.”
Emily · Jan 2026 · verified · amazon
It helped us identify that lead paint was only in one specific area (our closet), and now we know exactly what to address. The swabs gave false positives, this is far more reliable.
