How to Clean and Maintain Your OUAI Refillable Bottles for Long-Lasting Use

Refillable bottles are a sustainable choice that reduces waste and lets you enjoy your favorite OUAI products again and again. But to keep them performing well and your formulas fresh, regular cleaning and maintenance are essential. Whether you're refilling your shampoo, conditioner, or body wash, a little care goes a long way.

In this guide, we'll walk you through the best practices for cleaning and maintaining your OUAI refillable bottles, so they stay hygienic, functional, and beautiful for years to come.

Why Clean Your Refillable Bottles?

Over time, residue from products can build up inside your bottles, leading to clogged pumps, bacterial growth, or changes in the product's texture and scent. Regular cleaning prevents these issues and ensures each refill feels as fresh as the first use. Plus, it's a key part of a sustainable beauty routine—by taking care of your bottles, you reduce the need to buy new plastic containers.

OUAI refillable bottles are designed for durability, but they still need a little TLC. Whether you're using them for your shampoo, conditioner, or body cleanser, a quick clean between refills will keep them in top shape.

• Prevents product buildup and clogging
• Maintains hygiene and prevents bacteria
• Extends the life of your bottles

Step-by-Step Cleaning Guide

Start by emptying any remaining product. If the bottle has a pump or nozzle, remove it if possible. Rinse the bottle and cap with warm water to remove loose residue. Then, fill the bottle with warm water and add a few drops of mild dish soap. Screw the cap back on and shake vigorously for about 30 seconds. Let it sit for a few minutes, then rinse thoroughly with clean water.

For stubborn residue, use a bottle brush to scrub the interior. Pay special attention to the neck and threads where product can hide. Rinse again until no soap remains. For pumps or nozzles, soak them in warm soapy water for 10 minutes, then rinse and dry completely before reassembling.

Allow all parts to air dry upside down on a clean towel. Make sure there is no moisture inside before refilling—this prevents dilution and bacterial growth.

• Use mild dish soap—avoid harsh chemicals that can damage the bottle
• A bottle brush helps reach tight spots
• Dry thoroughly to prevent mold

How Often Should You Clean?

We recommend cleaning your refillable bottle every time you finish a product and before adding a new refill. If you use the same product consistently, a monthly deep clean is still a good habit. For products with thicker formulas like conditioners or cleansing balms, more frequent cleaning may be needed to prevent buildup.

If you notice changes in the product's smell, texture, or performance, it's a sign that your bottle needs a clean. Don't wait—a quick wash can restore your experience.

• Clean after each refill for best results
• Monthly deep clean for consistent use
• Watch for signs of buildup or odor

Tips for Maintaining Your Bottles

To keep your OUAI refillable bottles looking and working like new, avoid using abrasive sponges or brushes that can scratch the surface. Store bottles away from direct sunlight and extreme temperatures, which can degrade the plastic over time. Always ensure the cap is tightly closed when not in use to prevent leaks and contamination.

If your bottle has a label, try not to soak it in water for too long to prevent peeling. Most OUAI bottles are dishwasher safe on the top rack, but hand washing is gentler and recommended for longevity. For pumps, a quick rinse after each use can prevent clogging.

By following these simple care tips, your refillable bottles will serve you well for many refills, supporting a more sustainable beauty routine.

• Hand wash recommended for longevity
• Avoid direct sunlight and heat
• Tighten cap after each use

Refilling Your OUAI Bottles

When it's time to refill, choose your favorite OUAI product in a refill size. For example, the Thick Hair Conditioner - Travel is a convenient option for on-the-go or to try before committing to a full size. Simply pour the product into your clean, dry bottle, and you're ready to go.

If you're switching product types, make sure to clean the bottle thoroughly to avoid mixing residues. This is especially important when moving from a shampoo to a conditioner or vice versa. A clean bottle ensures the integrity of your new product.

• Use refill sizes to reduce waste
• Clean thoroughly when switching product types
• Dry bottle completely before refilling
