if your grout had not been seal then it will be hard to clean and if you clean with acid the grout will be change color.
You need to use a stripper. Home depot has great tile cleaners and strippers. You must reseal the tile and grout after use. It is a big job, but it works. When we moved in our house the tile was white with black grout. Moved the fridge to find that the grout was lt. grey. Used this method and the grout came clean. Good luck
You remove oil based paint on tile floors by using a strong detergent mixed with water and a soft cloth
First, clean the tile and grout with a harsh cleanser such as T.S.P. Next, apply a bonding primer to the tile with a brush or roller. It can be oil-based or water-based, and you can thin it slightly if needed to get a smooth, even coating. Once the primer is dry, apply your alkyd (oil-based) paint over the primer with brush or roller.
Remove the oil pan from the engine and clean it with kerosene.
I recommend consulting the flooring manufacturer, however, my experience suggests that the application you describe is an acceptable risk. Adhesion of floor tile to grout is more important than the grout's adhesion to the painted concrete substrate. Uniform stability is very important, and you have that with your painted concrete slab. When I had my tile done, the company used a primer to rough up the smooth surface.
In an engine, the oil filter, but only for a limited time.
Assuming you mean oil pump, changing the engine oil and oil filter on a regular basis with quality motor oil will help keep the internal engine parts as clean as possible.
Oil contains detergents that clean your engine and suspend soot, deposits, & dirt in the oil. The air and oil filters remove most of the larger particles but some get in the engine and stay suspended in the oil which causes it to turn black. Oil is not only a lubricant and helps cool the engine, but it also keeps the engine clean.
You might have to much oil in the engine. Check oil. Clean spark plugs. (remove and use sand paper to clean)
First, you need to clean the tiles with a product that will remove soap scum. Scrub or brush both the tile and its grout. Then spray a bleach solution (1cup of bleach to 1 gallon of hot water) and let sit awhile. Do this only in well ventilated areas. Wear gloves, and old clothes you don't care about in case the bleach splashes. Depending on how long since the grout has been cleaned, you may need to repeat the process several times. If you notice the grout is cracked, or missing you will need to scrape it out (an old screwdriver works well) and replace the grout when the whole area is dry.
Not far, anyway. The engine flush is not engine oil ... its only purpose is to, hopefully, clean the inside of the engine areas. That's why it's called "Engine Flush" and not "Engine Oil". Get it out and put the new oil in soon.
AnswerIf it's a hard, smooth glazed finish, you should be able to remove it with whatever it says on the stain can to thin or clean up with. Probably mineral spirits.If it has a more porous or pitted surface, you can probably forget it.PhilI found this solution completely by accident after spilling 8 oz of red mahogany stain on while tile/grout walls etc.. after cursing like crazy and googeling-- which I found nothing except how to remove stain off of hands-- Olive Oil. Works absolutely wonderfully, I wiped up as much as I could with paper toweling, dumped olive oil on the floor and started wiping (while still cursing). Stain came off of everything including the white walls. Then I used really hot water and dawn dish soap to get off of oil. Good Luck!!
