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.

One bottle does your entire house.
170 sprays. Every dish, every windowsill, every cabinet pull, every painted doorframe. One Saturday, every surface that touches the grandkids.
Test with Kits, Not Kids.
I'm Eric. I spent four years getting obsessed with one question, how do you actually find lead in a house before the kid finds it first.
Most of my early customers found me only after their kid's blood test came back elevated. By that point the lead had been in the body for months. The dish. The cabinet. The window sill. Sometimes it was on the dollar-store toy in their backpack. The pediatrician's blood test is a smoke alarm that goes off after the fire.
I spent over $200,000 on XRF spectrometers, mass-spec analyzers, and reference standards because I wanted to know exactly what lead does inside a house, where it hides, how it transfers, when it actually shows up in a kid. I knew the answers had to fit in a $75 bottle, or nobody outside a lab would ever use them.
You may know me from Instagram, @ericeverythinglead. I've tried every way I can think of to get this test kit in front of the people who need it. But here's what I learned along the way: just having the test kit isn't enough. So I built free digital companion tools to go with it, the baby-food database, the Universal Food Calculator, the Lead Framework field manual. The kit shows you where lead is. The tools tell you what to do about it. Together they solve the whole problem, not just half of it.
The new way is simple. You test the house before the kid arrives. You find it. You remove it. The kid never has to be the test.

It's not just the dishes.
If your home was built before 1978, the odds are stacked. About 87% of homes built before 1940 still contain lead-based paint. Roughly 35% of all US homes pre-1978 still have it somewhere on the interior or exterior, often in the doorframes, the windowsills, the kitchen baseboards, the closet trim, the spots that lose paint when a door rubs them.
The decoration on the bowl is one path. The chipped paint where the closet door scrapes the frame is another. Sometimes both are in the same kitchen. The kit checks both in the same afternoon.
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:
- They handle older items. The cup grandma serves their juice in. The vintage spoon. The decorative teapot they're fascinated by. The ceramic figurines.
- They eat off your dishes. Your china, your bowls, your everyday set, most of which is older than the household they normally eat in.
- 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.

"My dishes have been fine for 40 years."
For an adult, mostly. A two-year-old is not an adult. Their brain is still building, they put hands and toys in their mouths, and the lead is in the painted decoration that touches food, not the dish itself. "We all turned out okay" was never tested on a toddler's developing brain. Thirty seconds tells you for sure.
"I'm not techy. I'll mess it up."
If you can hold a flashlight, you can do this. Spray the spot, shine the light, look. Lead glows green. No app, no numbers to read, no chemistry. The instructions are one page and the reference card shows you exactly what a positive looks like.
"I'm not throwing out my mother's china."
You don't have to. Finding lead doesn't mean the trash. It means you take the few real pieces off the table the grandkids eat from and keep them on the shelf where they belong. Most of what you test will be clean, and now you'll know which is which.
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).
Audit every dish, window, and cabinet in your house for lead by Sunday dinner. Without a contractor, a lab bill, or throwing out the china your mother gave you.
The kit. The book. The database. Everything you need to know what to swap, what to keep, and what to put on a high shelf, before the next visit.
If you find lead in your house, you're already ahead. The cheapest single-sample lab test is $35. You'd pay $175+ just to do your kitchen. You did your whole house in one afternoon.
If you don't find lead in your house, mail the kit back. We refund the $75. You keep the book. You keep the database. No survey, no email asking you to reconsider, no win-back coupon. Either way you walk away knowing.
Soil-analysis bonus is included free through May 31. After that it's $40.
What's worth checking in your house

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

Questions grandparents ask
★★★★★"I keep finding all of the lead in my late parents' house. Thankfully I'm able to chuck most of the items. Highly recommend!!"
— Marcella B., verified buyer · May 2026
★★★★★"Works as expected. I confirmed lead in some antique dishes I was suspicious of, and have peace of mind about the cookware and dishes I use."
