Manual caulk guns are the most basic type, requiring physical effort to operate. They consist of a trigger mechanism that pushes a rod forward, dispensing the caulk. These are cost-effective, lightweight, and suitable for small to medium projects. However, they can cause hand fatigue with prolonged use and may not provide consistent flow. Cordless caulk guns are battery-operated, offering more convenience and ease of use compared to manual ones. They provide a consistent flow of caulk with minimal effort, making them ideal for larger projects or professional use. The speed and pressure can often be adjusted, allowing for precise application. However, they are more expensive, heavier, and require battery maintenance. Air-powered caulk guns, also known as pneumatic caulk guns, use compressed air to dispense caulk. They are highly efficient and provide a smooth, consistent flow, making them suitable for industrial or large-scale applications. They require an air compressor, which adds to the cost and limits portability. These guns are less physically demanding but require some setup and maintenance of the air system.

To clean a caulk gun after use, follow these steps: 1. **Release Pressure**: Immediately after use, release the pressure on the caulk gun by pressing the release lever. This prevents more caulk from being pushed out and makes cleaning easier. 2. **Remove the Cartridge**: Take out the caulk cartridge from the gun. If there is any leftover caulk, seal the cartridge with a cap or plastic wrap to preserve it for future use. 3. **Wipe Excess Caulk**: Use a rag or paper towel to wipe off any excess caulk from the nozzle and the gun. Be sure to clean the trigger and any other areas where caulk may have dripped. 4. **Clean the Nozzle**: If the nozzle is removable, take it off and soak it in warm, soapy water. Use a brush or a toothpick to remove any dried caulk from inside the nozzle. 5. **Use Solvent for Stubborn Caulk**: For stubborn or dried caulk, use a solvent like mineral spirits or rubbing alcohol. Apply the solvent to a cloth and rub the affected areas. Be cautious and follow safety instructions when using solvents. 6. **Clean the Plunger**: Extend the plunger rod and wipe it down with a cloth soaked in warm, soapy water or solvent. Ensure all caulk residue is removed to prevent it from hardening and affecting future use. 7. **Rinse and Dry**: Rinse all parts with clean water to remove any soap or solvent residue. Dry thoroughly with a clean cloth to prevent rusting. 8. **Reassemble and Store**: Once all parts are clean and dry, reassemble the caulk gun. Store it in a dry place to keep it in good condition for the next use.

Accessories for caulk guns enhance their functionality and ease of use. Here are some common ones: 1. **Nozzle Tips**: These come in various shapes and sizes to control the flow and application of the caulk. They can be cut to different angles to suit specific tasks. 2. **Extension Tubes**: These are used to reach tight or awkward spaces that are difficult to access with a standard nozzle. 3. **Caulk Smoothers**: Tools like caulk finishing tools or spatulas help in smoothing out the caulk for a clean finish. 4. **Caulk Caps**: These are used to seal the nozzle between uses, preventing the caulk from drying out. 5. **Caulk Removers**: Tools designed to remove old caulk efficiently without damaging the surface. 6. **Dripless Mechanisms**: Some caulk guns come with or can be fitted with mechanisms to prevent excess caulk from oozing out after the trigger is released. 7. **Battery Packs**: For electric or battery-operated caulk guns, additional battery packs can be useful for extended use. 8. **Hanging Hooks**: These allow the caulk gun to be hung on a ladder or tool belt for easy access. 9. **Carrying Cases**: Protective cases for storing the caulk gun and its accessories, keeping them organized and safe from damage. 10. **Cleaning Tools**: Brushes and other cleaning tools help maintain the caulk gun and prevent clogging. 11. **Replacement Parts**: Such as plungers, rods, and springs, which can wear out over time and need replacement.
