Where to buy caustic beads? Pressure Washing

16 oz per gallon of water water first add beads second stir slow.
Going to test this mix on my own driveway to test out with. It has VERY heavy bad oil spots so I hope this works well and can get some good/before after shots. What other precatuions should I look out for. Pre-wet the asphalt and landscaping and do a heavy rinse?
 
Yeap and dont put this mix on your back you will get injuries from this at these ratios.Mix in a pail then let it cool down then pour to sprayer.
 
Causitic is good for food grease.. butyl...sod metasilicate...and some others are better for oil. .caustic by itself will make the oil wiggle a bit and is a great additive for good oil removal soaps. ..russ has a pack that you can mix caustic with for a good oil removal..if it just a spot no need to put in a sprayer just mix in a bucket and scrub it in..works better with agitation anyway.
 
Hal that looks like very inclusive mix of everything needed to be a kick ass degreaser. Everything seems straightforward....enough...but couldnt track down stephonate 40 ..is that correct spelling. .we have been trying new blends for degreasing and would like to try the gimme you just layed out. have you been In the chemical industry before? Most pressure washers I talk with lately kinda cock their head sideways when you start talking abou a chelating agent and such
 
That's the generic name it helps the stuff blend together and clear up the mix.Its very good an it works well.I never have been in the chemical side of thing but it might be a avenue to explore.
 
Would you recommend the 16oz/1gal of water for a fast food drive thru area?
