Be the grandparent who tests for lead before the kids visit.

You raised your kids in the era when nobody knew. You don't have to do the same to your grandkids.

A quiet fact about your generation

If you were a child in the United States between roughly 1940 and 1985, the average pediatric blood-lead level in your cohort ran 12–17 µg/dL. The CDC's current "elevated" threshold is 3.5 µg/dL.

That isn't a judgment of you or your parents. It's a fact about the era. Lead was in the gasoline, the paint, the food cans, the plumbing solder, the toys. Nobody told anybody to test for it because nobody had the tools to find it. Most of your generation grew up with measurable lead body burden that today's pediatrician would intervene on.

Your house is from that era too. The paint on the trim. The fixtures in the bathroom. The Pyrex on the shelf. The brass on the doorknobs. The decorative ceramics in the dining room hutch. The vintage toys you saved for the grandkids.

The lead is still there. The difference between then and now is that we have a 30-second consumer test that lets you find it.

Why this matters when the grandkids visit

Grandkids do three things in your house that put them at higher risk than they'd be in their own house:

1. They handle older items. The cup grandma serves their juice in. The vintage spoon. The decorative teapot they're fascinated by. The ceramic figurines.
2. They eat off your dishes. Your china, your bowls, your everyday set, most of which is older than the household they normally eat in.
3. They put their hands in their mouths in your space. Your house, your dust, your friction surfaces, your doorknobs, your brass cabinet pulls.

None of this means your house is unsafe. It means there are specific things worth checking before the kids show up, and once you've checked, you don't have to think about it again.

What Fluoro-Spec does

Fluoro-Spec is a methylammonium-bromide reagent that you spray on a surface and look at under a UV flashlight. If there's bioavailable lead, the surface fluoresces green. Thirty seconds. No lab.

It's the same chemistry that solar-cell researchers in the Netherlands published in Nature Chemistry in 2018. We refined the formula for consumer use and got it through EPA TSCA registration so it can be made and sold legally in the U.S. (LVE No. L-25-0206).

What's worth checking in your house

1. Decorated dishes and mugs you serve grandkids food in. Especially the painted band that contacts food or lips.
2. Vintage Pyrex and decorated cookware, exterior decoration is the issue, not the base glass. (See our vintage Pyrex guide.)
3. Pre-1978 paint surfaces, door frames, window sashes, baseboards in any room the kids spend time.
4. Brass fixtures in bathrooms and kitchens, particularly faucets if the grandkids drink from the tap.
5. Vintage ceramic figurines and decorative items the grandkids might handle.
6. Hand-me-down toys you've saved. Pre-CPSIA (pre-2009) painted toys are often elevated. (See our vintage toys guide.)
7. The kitchen faucet you fill the kids' water glass from, particularly if it's been sitting overnight.

A practical note on calm

This isn't about scaring you. It's about giving you the same thirty seconds of certainty about the painted bowl that you have about the smoke detector. The point of testing is to find the few items that are real concerns and retire them, not to live in fear of every old object in the house. That's the difference between practical lead safety and the influencer-driven panic that's become an industry.

For dose context, what an elevated test result actually translates to in terms of childhood exposure given how often the grandkids visit, use bloodleadcalculator.com. It's a free tool I built that does the math.

About me

I'm Eric Ritter. I've been making consumer lead detection products since 2019. The reason I built Fluoro-Spec is that the existing options for testing lead in your home, $300+ professional inspectors, $5 hardware-store swabs that miss what matters, or the social-media panic industry, were not serving the people who actually want a calm and accurate answer.

Fluoro-Spec is manufactured under U.S. EPA TSCA Low Volume Exemption No. L-25-0206. It's the first U.S.-compliant consumer perovskite-test product. Same chemistry the imported alternatives use, just registered, regulated, and shipped from the U.S.

FAQ

I'm in my 70s. Is this still worth it?

For yourself directly, the lifetime exposure question is answered by your blood test, and your doctor can tell you where you are. For your grandkids visiting your house, absolutely worth it. The biggest difference Fluoro-Spec makes is identifying which specific items in the house are sources, before the next visit, so you can take them out of rotation.

What if I find lead in my favorite vintage piece?

Display, don't use. The cultural and sentimental value of vintage decorated items is real. Keep them on the shelf or in the china cabinet. Just don't serve food or drink in them. That's the trade-off most collectors make once they know.

Is the reagent safe to have in my home?

Yes. It's a methylammonium-bromide solution in isopropanol, a small organic salt in rubbing alcohol. Per published safety data the reagent is corrosive but not acutely toxic at consumer concentrations. Standard handling: use the included gloves, wash hands, don't spray in your face.

Is this complicated to use?

No. Spray the surface, shine the UV flashlight, look. If it glows green, that's lead. If it doesn't, the surface is clean. Reading the test takes about 5 seconds.
