Shave Away Stains
You can try rearranging the furniture to cover up that spot on the rug, but you'd have better luck trying to get the stain out first. If it's just a little spill, water and a cloth might take it out, but for tougher stains, such as red wine or pet urine, you'll need a tougher solution. You don't have to look far; the solution is right in your shower!
A good spot cleaner for carpet stains is shaving cream. Take an old shaving brush or purchase a small, cheap paintbrush (that you keep just for this purpose) and use it to work the shaving cream into the stain. Then use a clean, damp rag to wipe up the shaving cream and the remnants of the stain. Blot the area dry with a clean, white or color-fast cloth.
