I am all for buying new toys, I mean tools. But how many bolts do you have to do? A plastic dishpan, a little gas, and a brush (and some good gloves) will do an excellent job. Followed by hot soapy water and a new brush. That is how I clean them before tossing them in my blasting cabinet. If you have a LOT to do, go for the new tool. If not, you can save the money.
