This stuff is ridiculously good.I’m usually pretty cheap when it comes to getting supplies so products like this would typically not get any attention from me and I would get plain acetone or alcohol for cleaning. However, this stuff has taught me I just made more work for myself.You do not need very much of this product to clean a lot. I have had this gallon for a couple weeks now and have used it to clean a lot of stuff (in the middle of a kitchen remodel). For example, I used a rag lightly dampened with this product and was able to clean 12 cabinet doors throughly without needed to reapply the product.The thing it cleaned that surprised me the most was my commercial deep fryer. I got it used from a restaurant that recently upgraded their equipment. When I got it, there was several areas that the old grease was so thick on that even a pressure washer couldn’t budge it. I took a rag saturated with this product and left it laying for 15 minutes on an area that was giving me trouble getting h clean. After that, all the old caked on grease loosened up and I was able to wipe the bulk of it away with a rag before finishing with my pressure washer.The product is so powerful you will need to make sure you have the appropriate PPE while using it. I suggest safety glasses and acetone resistant gloves at the bare minimum and ideally also using a chemical resistant apron, respirator and a face shield. Also, make sure you use this in a well ventilated area away from any open flames. If you use this indoors, make sure you open the window and place some fans to make a draft to get the fumes out. If you don’t, you will be smelling this solution for a long time.Only thing I wish to see some improvement with is the spout and lid. Once you beak the metal tamper seal, you will constantly smell the solvent unless you reseal it somehow like I did. However, this is not a deal breaker to me.Considering everything I said and my past experiences using other products, I do think this is worth every penny. Especially when considering the time you will save compared to cleaning with other products.
