Are you having trouble removing the oily solvent from your base? Is your attachment not as good as it could be? This kind of problem bothering some people for a long time, but that’s not a big deal.
There are a few things to remember any time that you're rinsing a lay space. you want to make sure that you're washing it base side up. If you would wash the A side system, it's going to cause the hair to come down through the lace and once it does that you're not able to fix it so number-one rule of thumb is to keep the B side up throughout this process. And if you're washing a base with long hair, you want to make sure that you're braiding the hair first, this will protect the hair and keep it from tangling.
You should have already removed as much adhesive as possible from your base. It's very important to remove all of the solvent or your adhesive will not stick for your next attachment. If the tape is on the lace part of the hair then gently brush the adhesive residue from the lace areas with a nail brush. For the residue on the skin areas of the hair piece, use a teaspoon or your fingernails to scrape it off.
Firstly, apply some soap, don’t use too much or will dry the hair out. Next using a slow stream of cold water and work the soap into the base using your thumbs as if there were a sting that you were trying to get out of the piece of clothing. Just continue with the cleaning process, and if you soak the hair in solvent, you may need to complete this process twice so that you remove all of the solvent from the base. Last, rinse it until there are no more suds in the system. Ta DA~ your hair system will be as good as new.
Little tips here, keep one direction when you rinse the item and all the steps must be gentle.
