Lead Test Kit Swabs Lead Paint Test Kit for All Painted Surfaces, Dishes, Metal, Toys, Wood, Test Results in 30 Seconds (30pcs)

I don't really have anything to compare it to. So far no lead.

The result is hard to explain, such as whether it is with water or vinegar, you can not get the right result, it will be false alarm. The quality is also very poor, get the goods feel very disappointed

I read up on using these test strips and found out they are not as reliable as we are told.I tested a few old coffee cups and while they said nothing to worry about, if the method of testing is not highly recommended am I really safe.. It worked as advertised, until I find out differently, it worked...

In general-They arrived with a manufacture date of 3 weeks prior to delivery-Claim to be good for two years from the date of manufacture-Package makes no mention of using the product within any time frame from opening the container-The container features an air tight foil seal under the lid-The instructions make no mention of using distilled water or otherwise trying to prevent contamination of the water from potentially producing false positives for lead in test items-The instructions make no mention of a time frame one can continue to search for a lead reaction so if you keep testing more items you do so at your own risk. This worked well for me howeverMy tests and resultsI ran a single swab over six pieces of Corelle Corningware arranged from newest to some of the first Corelle made. When I got to the oldest and most worn piece, the portion of the swab in contact with the test item flagged as containing lead, see the first orange tip photo. I then used the opposite surface of the swab yet unchanged in color to test a few more pieces which were lead free, then I wiped that unreacted spot on a lead pipe joint in the basement most certainly joined with leaded solder and that is the really deep color result in the second photo. That pipe was roughly the 10th item tested with the same swab.I used a second swab to check the first and got identical results except for that one I did not use a lead pipe. I let the swab sit in the open air for 10 minutes then rubbed it on known leaded electrical solder. The small area of the swab exposed to the solder quickly turned a fresh blood red.Note that the stick that the swab is fastened to will sometimes streak red. I believe that can be ignored. The result you are looking for will be where the swab touched the test piece and only where the swab touched the test pieceSo no fooling- these work. I would recommend using distilled water to prevent false positives from any possible lead in the water5 stars

I found this test kit easy to use but I didn’t find anything with lead. Even the item I suspected. I found the color never changes. I can’t really say if they work or if they don’t.

It did not change color to mustard yellow to do the test

I’ve used lead test swabs before. I recommend these because they are simple to use, perform well, and deliver accurate results in 30 seconds. I tested them by swabbing a piece of antique pottery that I know has lead in its glaze. As expected, the swab turned pink almost instantly, then a deep purple after about 30 seconds. The results can be read by comparing the swab to the color band at the top and bottom edges of the label. I encourage everyone to test household items, especially those items that are handled often by people or pets or are used for food and drink. A tip for testing: Make sure the surface is clean. Dish soap is not enough sometimes, especially if the item is metal. Clean the item with a powdered cleanser, like Comet or Bar Keepers Friend, or a metal cleaner that removes oxidation. Why? All metal oxidizes, just some oxidize very slowly and it’s not noticeable to the eye. The swab will pick up oxidized particles, so you may end up with a black swab that’s hard to read if an oxidized surface isn’t cleaned well before testing.

I believe that I now don't have anything around my house that I know for certain contains lead. I have repeatedly used these strips on some really old paint from the 1930's on my foundation walls, which I expected to indicate the presence of lead: they did not. I am under the impression that these strips may not render the most definitive results, but remain hopeful that they are accurate, which would mean that I do not have anything in my house that contains lead (we rebuilt, with only the basic frame and foundation remaining).After using this kit I did some reading up on testing for lead in your paint. I found that such tests are not considered to be reliable. At the same time, it is my impression that if it does show the presence of lead, then there is a pretty good chance that there is lead. So---in my case, I will still need to send a paint chip out to a testing laboratory or have a person come to the house with an XRF gun that can check for what elements are in the paint. If your test turns positive, it can save you a bit of money.

I dipped these in vinegar as the seller description states, rather than water as the instructions on the bottle. That should help any lead dissolve into the liquid and trip the test. I tested some solder I knew had lead in it first and it tripped the test. I also was able to identify an old door that was painted with lead paint, it turned dark immediately. In short these seem to do the job, though if the lead is under glaze / other layers of paint it might be hard to tell. If it is positive it certainly has lead in it. If it is not, it is hard to be certain there is not some there. It could be under the top layer.
