Cleaning Concrete From Your Tools

Difficulty Level (Easy, Medium, Hard, Insane):
Easy

Story:
I bought a bunch of tools at an auction lately and some of the concrete tools had old hard concrete plastered all over them. Obviously, they didn't take care of them very well. I also bought a 4' bull float with five 6' extensions and that one was pretty bad as well.

After building a little frame out of 2x4s and placing some plastic in the middle, I put the tools in the trough and poured 6 liters of white vinegar in it. All I had to do is let it soak for 10 minutes and scrub off the old concrete with a paint scraper and a wire brush.

The acidity of the vinegar dissolved the concrete to the point where it came off really easily. Best trick ever!

Amazon Debacle

I bought my wife an overhead projector because she's always wanted one and decided I was going to buy a spare bulb in case the current one broke. Luckily I found one on Amazon for $19.95 (US) with free shipping to Canada.

About an hour after purchasing and feeling great about it I got an invoice for $86 (CAD) and I was like "what???". Immediately I canceled the order thinking it would all be great and dandy, just to get an email that evening saying my order ha shipped. Again, I was like "what???"

I contacted the seller and they said to simply return it and they'd refund it. About a week later I got my package (it was about 3" by 3" by 3" and weighed less than 200g). I didn't even open the package but did a "return to sender".

Today, I got a notice that they reimbursed me, except, they only reimbursed me for $19.95.

After calling the credit card company, they said they can't dispute shipping charges and amazon said that I agreed to pay the $45 (US) WHICH I DID NOT.

Here's a screen shot of what I ordered as proof. Now it's back to amazon to see what they can do. What a crock!!!
