Review on 🧪 Efficient Lead Testing: 3M LeadCheck Swabs, Instant Lead Test, 8-Pack by Weng Ercoli

Expensive but useful. I use it not only to inspect the structure of my home, but also to detect lead in household items. Some surprises: A negative sample can become positive after eight hours when dried on lead ceramic tiles and in a bath. What a disappointment to know that newer homes still use lead products in the bathrooms! Good to know when renovating. Downloaded a negative onto a brass door hinge that should have enough lead to recognize it. The positive smeared on a few dust particles! Now we are shoes at the door of the house. As expected, a positive result was found on the ammunition body. As expected, it turned deep red on the stained glass. Metal kitchen pulls, I trust this result. I downloaded a negative for an old plaster, brass paint or gilding (metal) photo frame and clay - I'm not sure, I might want to repeat the test. Tip: You can get more tests by squeezing the contents into a four q glass measuring cup and using immediately. Cons: Sometimes turns bright orange, which is difficult to distinguish from red. A red color appeared on the gold portion of the "vegetable dyed" wool oriental rug (lead oxide?), but not on the smear itself, which does not confirm the results. At the same time, it distances itself from the children. Sometimes the stick itself remains negative while the liquid on the test object changes. Abuse may not always be accurate. May not show on all metals, may be slow or not show on ceramics. Orange Glowing Juice can be annoying to remove after testing
