    If you have a whiteboard marker, you can draw over it and then erase it. Works wonders.

    Alcohol or other solvents like Acetone work, but another easy trick a lot of people aren’t aware of is to go over a permanent marker with a dry erase marker, and then wipe it off.

    I shit you not, it works. We tested this across several whiteboards. First in inconspicuous spots, then on main parts of the board. Occasionally there was some residue remaining if the permanent marker stayed on for long, but the solvent they use in dry erase markers also erases permanent marker material.

    YMMV on a tape measure though…

      Even though this is a dick joke, I’d use isopropyl or ethanol no higher than 70%. Acetone tends to strip/degrade paint and if on a plastic substrate could degrade the plastic.

      Source: I work in an analytical lab for plastics and paints and I have made many mistakes.

        Acetone will work if nothing else works, but it’s just as likely to strip the underlaying paint off. You can mostly use alcohol to clean it and apply some acetone just on the actual stain with a qtip, that makes it less likely to be noticeable.

          Itll work but…It’s sharpie. I can take sharpie off a smooth surface with a kimwipe and elbow grease. Acetone is overkill and likely to damage your surface if it’s paint or plastic yo. Use a less aggressive solvent. Also we’ve destroyed a whiteboard or two with acetone.

      I’m surprised that someone isn’t selling measuring devices specifically for the penis

        I used to joke with a friend that we should start a business selling rulers that were inaccurate so that there was about 1/2 to 3/4 inch between the inch marks. We could have been rich

          I understand it with teenage boys, but I have always been fascinated with guys being so obsessed over how big their cock is. Seems to be common knowledge that women don’t really care because it feels no different to them. You will rarely hear a women talk about one that was so big that it hit their cervix.

            Or when you do, they talk about it negatively like “ouchie it was too big.” Sometimes ppl do prefer a girthier hog though.

        I recall a website from the web 1.0 days that sold rulers, soda cans, and other common everyday objects that were specially manufactured to be smaller than the actual object. The intent was to show someone your penis pic with an undersized soda can to make it look bigger.

    That took me a while. My first thought was it was an ad hoc durometer gage for cushion foam or jello or something, but the scale was backwards…

    Anyway. Isopropanol/isopropyl-alcohol/that-shit-in-the-medicine-cabinet will take care of it. I use it all the time.
