Wipe up as much of the spill as possible using old towels or newspaper. Mix detergent and water. Use a scoop of detergent per gallon of water.Scrub the area with the soapy water mixture and a soft bristled brush or a cloth. Rinse the area well with clean water and allow it to dry. Scrape away as much of the paint as will readily come off with a paint scraper or razor blade. Apply paint stripper or acetone with a brush per the manufacturer's instructions. Scrape away the remaining paint using the help of the paint stripper or acetone to soften it. Allow the area to dry and dispose of any residual bits of paint.
There are some commercial stain removers like "Gunk"™ that may or may not remove embedded fruit stains. For that, you may have to use Muriatic Acid. This is mean stuff ... try a dilution of 4 to 1 at first (four parts water, one part muriatic acid). Very important when mixing these two solutions: always pour acid into water - never pour water into acid. Muriatic acid cleans by etching the concrete, so you will want a method of rinsing the area off just as soon as the stain dissappears. If the 4 to 1 mix doesn't solve it, try 2 to 1, or as a last result, full strength from the bottle. Please be very careful ... the fumes from Muriatic Acid can be deadly.
As always, with any chemical, protect yourself (eyes, hands, face, etc) ... acid, if it gets onto your clothing or skin will immediately burn and you will require serious medical attention immediately.
Use a power-washer. It can be rented or bought in a hardware store. The power from a power-washer is high and will clean almost anything.
Stained concrete can be cleaned up quickly with just water and the correct pressure washing technique. Unfortunately, these older and more porous surfaces can also be damaged by the wrong tip or technique more quickly.
That is why aside from the regular nozzles used for pressure washers, it is best to use a Pressure Wash Surface Cleaner attachment from bestcargurus in cleaning flat surfaces such as brick and concrete.
A pressure washer surface attachment gets cleaning jobs done up to 4X faster than the usual spray nozzles. The splash-free skirt keeps you dry while you clean and you wonβt experience any streaking problems due to its ability to keep nozzles at a fixed height from the surface.
Stretch pantyhose, or some kind of mesh fabric to rub up and down on the deodarent stains.

You can remove stains or blemishes from a polyurethane watch by scrubbing it with a wet terrycloth that has been dipped in a solution of warm water and liquid dish soap. For tough stains, dip a melamine foam sponge into the solution, ring out and wipe the watch gently. Dry well with a clean towel.
For blue/pink stains on concrete, use a 25% solution of bleach (1/4 cup bleach with 3/4 cup water). Pour on stain, cover with kitty litter, wet litter with more solution. For lighter stains, allow to sit 15 minutes or so; for tough stains, leave overnight. Bleach may be harmful to plants growing near the treated area. Use Caution!
