Cleaning and Maintaining your Peak SqueezeUpdated 2 hours ago
Regular cleaning and backwashing help maintain flow rate and reduce clogging in your LifeStraw Peak Squeeze.
How to Clean Your Peak Squeeze
1. Backwash the filter
Backwashing helps keep the membrane microfilter clean and supports normal flow.
- Disconnect the membrane microfilter from the top cap by twisting counterclockwise.
- Screw the included backwash accessory onto the membrane microfilter.
- Place the open end of the filter into drinking water.
- Pull water up through the filter by pulling the syringe upward until it reaches the edge of the housing.
- Push water back through the filter by pressing the syringe downward until the water has fully passed through the other side.
- Repeat several times.
Routine Cleaning
1. Rinse the bottle components
We recommend rinsing the inside of the bottle, top cap, and mouthpiece after use and before storage.
2. Disinfect for deeper cleaning
For more thorough cleaning, disinfect the system as follows:
- Mix 1/4 teaspoon of household bleach with 1 to 2 cups of water.
- Submerge the end of the filter into the bleach solution so the end is fully covered.
- Use the backwash accessory to push and pull the solution through the filter several times.
- Rinse with tap water.
- Clean all mouthpieces, caps, and removable parts for more complete disinfection.
Storage Reminder
To help maintain performance during storage, avoid letting the membrane dry out completely. Storing the filter with a saline solution made by mixing 1 teaspoon of salt with water helps support the hydrophilic properties of the membrane and may also help prevent mold or algae growth during long term storage. If the membrane becomes completely dry, it can be difficult to get water to flow through again.
Important Care Notes
- Backwash the filter before storing it.
- Rinse the bottle, cap, and mouthpiece before storage.
- Clean removable parts thoroughly during routine maintenance.
- Avoid allowing the membrane to dry out during long term storage.
