Before you use a solvent, make sure it's safe for the purpose and isn't going to damage your gun. These substances are typically flammable. If used for the wrong purpose they can combust or cause an explosion. Common uses and potential issues are described below.
GUN BORE CLEANER : Standard bore cleaners aren't generally suggested for airguns but can be used in certain cases. It can dissolve o-rings so it shouldn't be used for models like Marauder Rifle, Marauder Pistol or Bulldog .357 which have o-rings inside the back of the barrel. It could also seep down around the transfer sleeve in 13XX, 22XX and PCP models causing damage to the gasket. We suggest removing the barrel for cleaning and removing the internal o-ring where applicable. Bore cleaner is corrosive to brass barrels and other parts made from, or plated with, soft metals.
In general airgun barrels should be cleaned with airgun oil only. They don’t generally develop lead fowling like firearm barrels do but tend to accumulate dust and particles that should be removed periodically. Petroleum-based airgun oils work better than silicone types for this application. For PCP and break-barrel models that require silicone oil for maintenance, petroleum airgun oil is only safe for cleaning the barrel and oiling pellets. It should not be used inside a compression chamber, pressure tube, fill nipple, valve, filling equipment or any other component that contains or develops high pressure. For CO2 and variable-pump models petroleum-based airgun oil is safe for internal components and works the best.
PENETRATING OILS : WD-40, Liquid Wrench and similar petroleum solvents are highly flammable. These should not be used to lubricate any part of an airgun, tank, pump or introduced into any pressurized component. Doing so could cause an explosion.
ACETONE : Commonly used to clean metal parts for touch-ups and refinishing. It will dissolve many plastic parts, paints and coatings. This includes grips, forearms and some of the markings on sights. Acetone is flammable and the fumes are explosive.
ISOPROPYL ALCOHOL : Commonly used to clean parts, removes oil and grease. It won't dissolve plastic or paint. It's flammable and can produce explosive vapors in a small enclosed space.
DISH SOAP : This is an excellent parts cleaner that dissolves oil and grease. It can be used undiluted or mixed with varying amounts of water and easily rinses clean. Steel parts should be dried immediately and oiled to prevent corrosion.
