Fresh stain on concrete

[Mountain View]

What is the best way to remove relatively fresh stain (less than a week old) from concrete? I've tried stripper at about 4-5 oz/gal, nothing. Xylene, Acetone, nothing. Ran out of Mineral spirits but the little I had seemed to do so-so.

If the stain is already dried, which I'm suspecting it is mineral spirits won't do much for it. Try mixing your stripper strong & mixing in some butyl type degreaser and saturate the concrete. Best thing to do is mix it in a bucket and then just dump the bucket out on the concrete. A pump sprayer can't keep it wet enough in the hot sun. Let it dwell for 15 min.'s or so. Then use a surface cleaner if you have one or wand and wash it right off. You should get most of it out of the concrete.

It seems to be easier to clean concrete than pavers. I have some pavers to clean up stain drips from an employee who didnt bother to lay plastic. Needless to say he is no longer working with us but I need to get them cleaned up or pay to have the pavers replaced and I think I am going to get hosed for a lot of money.

it's one of many different brands of strippers, usually methylene chloride based. If you're using an oil based stain you shouldn't have to use anything like that. But in the worst case scenario go to Home Depot grab a can of Kleen Strip(the one with the little spray bottle attached to the side) and spray the areas of stain and pressure wash off, wear heavy duty chemical resistant gloves with that stripper.
