I know about nasty stains. We have had two dogs and two cats, the dogs from pups to death, and the cats from teens to senility and death. There have been careless people in our houses. We have been careless at times.
I think I am repeating myself, but I wrote a long time ago about when I stepped off a ladder onto a full tin of paint and tipped it over. No more painting was done that day as I spent the rest of the day cleaning up, almost successfully.
Of course it is a natural reaction to yell at a dog if it does something wrong, so when he stepped into the paint tray and I yelled, he took off, leaving a wonderful trail.
We were in the middle of polishing woodwork when friends called in and one of them kicked over the bottle of Marveer. That was fairly challenging.
Another friend used to like to make us and himself coffee when he visited. He would overfill the mugs and then carry them with his less than steady hands to us. Much coffee dribbling.
Little Jo has caused her fair share. Stains on the carpet were almost a thing of the past until she arrived. The latest was a cup of milk.
The mega stain was when R dropped a bottle of red wine on the kitchen floor tiles, next to the carpet. As well as staining the white tile grout, it flowed onto the carpet. Not quite as bad as upending the paint tin, but pretty bad. The paint was on old carpet though, the red wine here. Bleach cleaned the grout.
In times past, I sometimes used to step in grease at work, and then walk it on the carpet. That actually was easy to clean.
You only really need two things to spot clean carpet, white spirits, aka Shellite, for grease stains, and wool wash for the rest. Bleach to clean the grout was a one off.
If none of those work, you just live with the stain.
So, c'mon. Fess up. What is the killer stain you have made?
