Today after doing some Mexican tile cleaning I left some wand skip marks...Not good...Maybe happening more as lighting in the home can be a real issue, however, my vision even with glasses might leave your areas unsightly...I run into this problem when moving too fast, or uneven edges of tile and grout...
Kinda sucks when you make a difference on someone's floors and leave any of these marks...Most don't even alert you to let you know of these problems...Looks like I'll be making a trip back to this home clear across town, or potentially lose a client...
