Montana Acetone Spray, also referred to as Cap Cleaner, is an essential universal thinner and cleaning agent. Its transparent formula is highly effective at removing stubborn residues such as paint, lacquer, silicone, wax, tar, and grease. This versatile spray can be applied to a range of surfaces, including porcelain, glass, ceramics, and bare metals. Particularly useful for cleaning clogged spray can nozzles, the spray helps prolong the life of your caps. Simply attach the nozzle to the acetone can and spray to remove blockages. However, always test on a hidden area first, as it may cause reactions, particularly on plastic surfaces, which could result in etching.
