When looking for something as simple as paint thinner (mineral spirits), it can be tempting to go for the cheapest option in a given item’s range. And for odorless mineral spirits at my local store, Masterpiece was the cheapest brand there. Should I have gone with the more expensive option? Let’s see.
The container is fairly standard for a quart size bottle. The front label doesn’t have much art but gives enough information, and the back label gives enough “if you destroy property or yourself with this it isn’t our fault” warnings that you get the point. I’m not here to give safety advice but it should be said this stuff is very flammable and could do damage to you if used in a non-ventilated area.
There is a handle on the container for east carry that works fine. The only problem I have with it is the seal and handle conspire to make pouring difficult. It tends to “glug” which is something I’d be wary of.
The thinner itself works very well. When used on colored pencils (a trick I just found out about recently), it dissolves the wax and allows for easy blending. When used with paint, it does indeed thin oil-based paint quickly and is good for cleaning brushes and facilitating mixing. In regards to it being odorless it is, basically, though you will be able to tell if you’re in a room with an open container of the stuff, which is good to prevent too much inhalation.
Overall, it works, and I don’t regret going with the least-expensive option. I like it, and it’s far superior to turpentine (which is the stuff of the devil). It might not be the purest form of mineral spirits, and some are likely better. But for a beginner it certainly is effective at what it is advertised to do.
