Most plastic bottles use a pump dispenser, but the exact term can vary based on how it works:

• Lotion pump: Common for soap, shampoo, and conditioner; dispenses a measured amount per press.
• Foaming pump: Designed to aerate diluted liquid soap into foam; needs a thinner formula.
• Airless pump: Uses a vacuum system (no dip tube) to dispense creams or serums and help reduce exposure to air.
• Locking pump: A lotion pump with a twist-to-lock feature for travel or reducing mess.

Product listings typically specify the pump type, so checking the description can help you match the pump to your intended liquid.

There isn’t a set “expiration,” since lifespan depends on use and care. Many bottles used for home soap or shampoo can last months to years. Durability can vary by material (like PET or PP), the liquid inside, and how often the pump is used.

• Care matters: Keep bottles out of direct sun and high heat, and rinse between refills.
• Watch for wear: Look for sticking pumps, cracks, discoloration, or leaks.
• Replace parts: If the pump tires out, swapping the pump or bottle can be practical.

Checking the product description for material details and handling tips can help you estimate longevity.

Choose a size based on where you’ll use it, how often you refill, and the liquid’s thickness.

• Sink-side hand soap: 8–10 oz keeps counters tidy and refills manageable.
• Bathroom shampoo/conditioner: 12–17 oz is common; larger sizes reduce refills.
• Shower or household cleaners: 16–32 oz suits frequent use.
• Travel or minis: 1–3 oz or around 100 ml for portability.

Foaming pumps can stretch diluted soap, so you may not need a large bottle. Measure your space (countertop or wall area) and check capacity in the product specs to avoid oversizing.

Routine cleaning can help pumps work smoothly and keep bottles looking fresh. Here’s a simple approach:

1. Empty any remaining liquid and rinse the bottle with warm water.
2. Wash the bottle and pump parts with mild dish soap; avoid very hot water.
3. Press the pump several times in clean water to flush the dip tube.
4. For foaming pumps, run warm water through to help prevent clogs.
5. Rinse thoroughly, then air-dry completely before refilling.

Some bottles may be top-rack dishwasher friendly, but plastic types vary. Checking care notes in the product description and avoiding harsh chemicals can reduce wear.

Adhesive holders make wall-mounted pump bottles quick to set up without tools. A general process is:

1. Clean and dry the mounting surface; smooth tile or glass usually adheres best.
2. Peel the adhesive backing and press firmly for the recommended time.
3. Wait per the instructions before loading bottles, so the adhesive can set.
4. Place the bottles and test the pump gently.

Weight limits and surface compatibility can vary by product. For textured walls or humidity-prone areas, following the specific instructions and avoiding overloading can help the holder stay put.
