Immediately absorb the spilled fluid with a towel or paper. Do not twist the material used for absorption, push it with your full weight instead, and when it impregnates, replace it again. Repeat this process until the tucker does not become wet anymore. If you remove all moisture, then 95% of the stain can be removed without chemicals, and the removal of the residuary becomes easy. Already dried stains are hard, or even impossible to remove. Never scrub or scour the stain, the stain area!
If a bigger amount of fluid spilled out onto the carpet, mop up the most of the fluid with wet vacuum cleaner. Then the above described tucking process shall be started.
Scratch the contamination with a knife of spatula, then hoover it, if no traces left. Remove the residual contamination according to the attached list.
