Tide, the purple if it won't cut but this stuff is just plain nasty and is a last resort cleaner for me.
Purple will cut just about anything, next step up is phosphoric acid, think good toilet bowl cleaner but you have you remove the oil first.
As in ultra cleaning parts its one side and then the other in the baths.
I wonder if a commercial building if dumping purple down the drain is legal. While you can buy this at Home Depot home use and commercial use fall under different rules.
Being a carbide shop I'm not allowed to dump
any shop mop water even with no soap into the drain or city system. (heavy metals like carbide bad, cobalt bad
)
Few ever get caught but a friend of mine did. Big fines.
We dump to a 500 gallon tank, filter and evap. Put the remains in the carbide sludge which is sold like most do with metal chips.
Yes it is a pain and cost but you get used to it. You learn very quickly to not overfill a coolant tank.
Once in a ever great while I have to prove that this is being done to some inspector.
It's like "Really........ I have to document and prove my mop water procedures"??
Tide laundry soap is gentle, not nasty to inhale and does a fair job. Other laundry soaps probably do just as well and may smell more to your taste.
If you do filter reclaim these all present a problem as they "wash" your filters so a whole new problem.
To me how the mop or clean the floors floors is a big problem.
