    Default Muratic Acid

    I'm finally getting around to using what I bought last week. My question to those who have used it. I've read the MSDS sheet for it and was wondering, What's your guys process for using it?

    I've got a 5 gal container with lid. I put in about a quarter of a gal of distilled water and about a half gallon of the muriatic acid in this container. Then I put a couple of coupons that had some rust and mill scale on them in there and in about 3 minutes they were clean as a whistle

    Is it good enough to put those coupons in a gallon of fresh water and then pull them out to dry and then weld them?

    Default Muriatic

    You just put metal in an acid. You have to nutralize the acid before you do anything. Put them in a tub of baking soda and water. Remember your basic chemistry,(acids and bases). This should make the coupons ok.

    What are you using to handle the parts?
    Syncrowave 250DX
    Invison 354MP
    XR Control and 30A

    Airco MED20 feeder
    Thermal Dynamics Cutmaster 81
    Smith O/A rig
    And more machinery than you can shake a 7018 rod at

    I bought a pair of gloves that's made to handle muratic acid. They were like $7 or something like that.

    I'm not sure but as quick as it took off the rust and that wasn't even full strength! I would say it would. I have more coupons to do today so I'll try it
