Are there any plastic covers (or protectors or films) available that are more for long term (like about a year) as opposed to the short-term ones that last only 30-60 days.
We're about to rent a place, and the landlord has "no stains on carpet" demand. Since most of us are always at home and there are people who would certainly take food/drinks to their rooms, we are left with no choice but to cover up the carpet.
Yes, there are cleaning solutions available, but they are usually effective if you use them right away. Some of these people would completely forget about it for weeks.
Please understand that it can not be too costly. We'll there for a year or two, and we can not justify spending $500 for this cause.
Feel free to get creative. It does not have to be plastic, as long as food/spills don't reach the carpet.
