I have done a lot of non acrylic brush painting over the decades; used to buy and resell bikes at schoool, painted 6 cars and a lot of interior house work striving for brush mark free finish although with modern paints largely despair of the latter. I scrape paint out of the brush using the rounded back edge of a knife, wash successively in used turps and finally clean turps. Brushes which have become clogged are combed with a coarse wire brush, commecing above the bristles so these are not stabbed and severed.
A lot of amateurs seem to abandon the brush at end of task!
A workshop tool I have found very useful is a quality 8 inch direct reading vernier calliper. Instantly adjustable. Keeps the brain nimble and does not give a false sense of accuracy. Easier to hold than 6 inch. Can quickly sort dia and tpi for screws
Turpentine (which is also called spirit of turpentine, oil of turpentine, wood turpentine, terebenthene, terebinthine and (colloquially), turps) is a fluid obtained by the distillation of resin harvested from living trees, mainly pines. It is mainly used as a solvent, and as a source of material for organic syntheses.
White spirit (UK) or mineral spirits (US, Canada), also known as mineral turpentine (AU/NZ), turpentine substitute, and petroleum spirits, is a petroleum-derived clear liquid used as a common organic solvent in painting. There are also terms for specific kinds of mineral spirits, including Stoddard solvent and solvent naphtha (petroleum). Mineral spirits are often used as a paint thinner, or as a component thereof, though paint thinner is a broader category of solvent. Odorless mineral spirits (OMS) have been refined to remove the more toxic aromatic compounds, and are recommended for applications such as oil painting.
