GOTTA remember this!!! Easy way to get rid of mold in shower caulk - Someone else said: "I just tried it and OH MY does it work! I left it two hours and the mold was completely GONE!"...for clients who may be at their wit's end...or for yourself. :-)
a dried out marker and some white vinegar. Dip the tip of your marker into some vinegar. And your marker will work again! This has worked for me about 99% of the time. when it doesn’t it’s time to make water colors from your old markers. Most if not all, water based washable markers will work for this.
