Our refill sizes are a great option if you're an existing Foster customer, as they allow you to refill your current bottle up to 4 TIMES.
To help you get the most out of your bulk products, here is our guide to refill at home like a pro:
-
SHAKE your refill bottles to mix ingredients before refilling your empty bottles. This is the most important step to ensure each of your refill has the correct ratio of ingredients.
-
Pour using the measuring device that is sanitized. Be sure to leave some space in each bottle for the lid to prevent overflowing.
-
Do not back pour.
-
Tightly screw on lid and store.
-
Store your bulk bottles in a cool, dark, dry place to preserve the ingredients.
