Hello: I have a leaky tub spigot and I think the issue is the valve behind the handle. I just can't get an traction with any allen wrenches in the hole shown -- I think this is because of grime/mineral deposits/whatever that are caked over what I believe is a hex screw. I've tried digging through it with a random objects, have sprayed some chemical cleaner down it, and have had my friend and dad take a look too. We just can't get the handle off. Any ideas?
I've considered just paying a plumber, but everyone I call either wants to charge an outlandish amount upfront, won't come because it's in a condo so I can't guarantee a great spot to park their truck, or they just seem completely insane and scare me when they start asking personal questions and talking about Jesus. I'm a first time home owner, this can't be how life really is. Driving me insane! Any help is much appreciated.
