Wellgler's 200pcs Foam Cleaning Swab ,Lint Free Swabs,for Electronics Cleaning, Precision Equipment, aotomotive Detailing, Gun Cleaning, Effective Cleaning for Thin Groove Space(Blue)

I've used these religiously when the solder joints on PCB. Paired with 99% isopropyl alcohol cleans the solder flux flawlessly.

Good for cleaning USB ports. The spiral groove works well to extract dust etc. They hold up well when using alcohol, contact cleaner etc.

Use it for my baseball card restoration. Works well, wish it had a bit more foam on tips.

I was going to use this for cleaning small lenses. The material on the tip is so thin I am concerned it would scratch rather than clean. I used them to clean the interior of a 3mm copper pipe. It was okay but required several to do what I could do with another similar type swab.

I don't use this as intended but as a makeup correcting tool. I had thought to myself one day that I wished there was a Q-tip that was foam as regular Q-tips don't hold there shape so not very concise. Sometime after putting on lipstick or eyeliner you notice that it didn't go one side of your lip like the other or one eye has thicker liner than the other and I dip this into a little makeup to remove the part that is messed up. Works great. Just what I was looking for.
