Best ways to clean a carpet? My son has destroyed ours since he's the king of making a mess in three whole seconds. I vacuum every day but there are stains that I can't seem to get out of the carpet from things he's spilled that stained like instantly. He also cut his foot on a carpet staple and bled on the carpet. I had to take him to urgent care since he needed a tetanus shot since it was rusted to hell and back (we didn't know it was sticking up, it's been fixed). Well I obviously couldnt clean it up immediately so it dried and I can't get it out of the carpet with the regular carpet cleaner. Also having trouble with coffee stains since Henry's been in his stage where he just knocks mugs off of the computer desk. 😒 Violets already trying to push herself up with her arms during tummy time and already gets up on her elbows so I want to get he carpet deep cleaned and destained well before she's ready to crawl but none of the carpet cleaners Ive tried have worked. We don't have pets but I tried one for pet stains hoping it would be stronger and it didn't even touch the coffee stains let alone the blood smudge.
