These lead test swabs are easy to use & serve their desired purpose! Not to mention they are quite affordable too!

Hard to say if it worked? Said no lead in the paint of an old metal toolbox, so that's good? I had to do it twice, first time looked like a positive result, but surface was not clean enough. After a very thorough cleaning, came back negative. Bottom line, make sure you fully clean the surface first.

Safe to say by the testing of paint at Matsons bathroom with this product . Lead was at its minimum

I’d like to trust these swabs, but I’m not sure what they’re reacting to. I tried several tests. I started by rubbing the swab on a piece of lead-free electrical solder (wire), and got pretty much no reaction. Then I tried leaded solder (wire) and did get a reaction. So far, so good.Then I tried a joint on an exposed copper pipe in my basement. This is in a house built around the year 2000 which should have lead-free soldered joints. The swab reacted a deep red. This got me worried. I’ve had my water tested for lead previously and it showed no problems. I raised a kid in this house who is turned out pretty smart. I’m not so smart, but that might be for other reasons. I’m not so smart, but that might be for other reasons. I’m not smart…So, I did some more experiments and discovered that the test reacted to the bare copper pipe. True, the pipe was kind of grimy looking. I took a scrap piece of ½” copper plumbing pipe with a soldered elbow and cleaned it up shinny and rinsed it thoroughly. I tested the bare copper section as well as the soldered section. The copper once again reacted strongly, so checked the soldered joint which also showed a reaction. Oh, and this time I used distilled water instead of tap water to activate the swab.I figure, if the test is reacting to copper than how can I know if the soldered joint is reacting as well, and not just the copper? I kind of don’t think the copper pipe has too much lead, it’s made for drinking water systems. One more test; I took a piece of bare copper clad printed circuit board. It too showed a reaction, turning red after a short time.I’d like to have a test for the test.So, this test has raised more questions for me than it answered. It sent me down a rabbit hole looking for stuff about the active ingredient, Sodium Rhodizonate. Not clear, I found one reference that said these tests don’t work, but who knows? I don’t know, I’m not a chemist, I only play one on TV.Thus, I give this product a neutral rating for now and wouldn’t trust it with my brain. With my brain. Did I say that already? Can’t remember.

Used it on counters, windows, walls and peeling paint in a old house. It determined everything was lead free with exception of the rail of the staircase!
