Washing your triangle powder puff is an essential routine to maintain hygiene and extend its lifespan. Here are some tips to do it effectively:

1. Use Gentle Soap: Opt for a mild, fragrance-free soap or a specialized makeup brush cleaner. These products are designed to break down makeup and oils without damaging the material of your puff.

2. Warm Water Rinse: Start by rinsing your puff under warm water. The warmth helps to open up the pores of the puff, allowing for a more thorough cleanse.

3. Lather: Apply a small amount of your chosen cleaner onto the puff and gently work it into a lather. Be sure to reach all areas of the puff, especially those that come into direct contact with makeup.

4. Rinse Thoroughly: Rinse the puff under warm water until all the soap is removed. It's crucial to ensure no soap residue is left behind as it can irritate the skin and affect the performance of your puff.

5. Squeeze Out Excess Water: After rinsing, gently squeeze out any excess water. Be careful not to twist or wring the puff as it can damage its shape and structure.

6. Air Dry: Lay your puff flat on a clean towel and let it air dry naturally. Avoid using a hairdryer or placing it directly under the sun as extreme heat can damage the material.

7. Regular Cleaning: Depending on how often you use your puff, aim to clean it at least once a week. Regular cleaning prevents the buildup of bacteria and extends the life of your puff.

Remember, the key to effective cleaning is gentleness. Harsh cleaning methods or products can damage your puff and reduce its efficacy.
