I didn't go out, since there wasn't anything that really interested me. Anddd, I should be saving money! But I did recently buy a palette (that I will do another post on soon) from Marshalls. I hesitated a little since it was open, but it didn't look like it had been touched. Plus, it was a really great deal, compared to the original price! Besides, all the eyeshadows were in order, no cracks or missing pieces or dips in the product, etc. But I thought I'd be safe and disinfect them. Just in case, since it's better safe than sorry.
I remember reading somewhere that you could take a tissue with alcohol on it and wipe the top layer of your powder products. But, I wasn't exactly sure and didn't want to ruin the product before I had a chance to use it, so I Googled it. Found my answer and thought I'd share!
Basically, you spray your products with 91% isopropyl alcohol (rubbing alcohol) and let it dry. No damage done and you've got clean products! If you can't find the 91%, I read that you can also use 70%, which is more widely available and what most people have in their medicine cabinets/bathrooms. From what I read, the percentage is just how fast the alcohol will dry; higher percentage dries faster. Hope this helps~
