:The last time I bought a gallon of mineral spirits (about 18 months ago, :I believe) it cost $2.50. That was very high I thought at the time. :Yesterday in Lowe's, I noticed the cheapest brand was selling for $8.00! : Is there any reason for this other than plain greed and price gouging? :Paul in San Francisco
I haven't bought any paint thinner for a number of years. I remember it being pretty cheap, maybe $2/gallon, and I have two gallon cans (one metal the other plastic), in varying degrees of fullness. I generally pour a little off into glass jars from which I get whatever paint thinner I need for a variety of purposes.
I usually recycle my paint thinner. Thus, if I clean a brush with paint thinner, I pour the liquid into another jar which is kept for the purpose. After a time, clear liquid rises to the top and the impurities settle to the bottom and form a firm substance. Thus, I can decanter off what is essentially simply clear paint thinner from that jar when I next need a bit of thinner. Using this practice is a big part of the reason I don't need to buy thinner very often. I even reuse thinner I use to clean the chain on my bike, after the sediment has settled out. Reusing it is also better for the environment, certainly better than pouring it down the drain or allowing it to evaporate (unburned hydrocarbons).
