If you are a landlord who has been left with a filthy rental then you will want to have the rental back in proper shape as quickly as possible, so you can move another renter in. If you have decided to take on the task of cleaning the rental unit yourself to save some money, then you can follow the tips here to have the rental unit ready for a new family as quickly and as hassle free as possible.
Start with junk removal
Before you start cleaning anything, you are going to want to remove everything from inside the unit. It's going to be much easier to get the whole place clean once it is completely vacant. You want to make sure you have a couple of safety items for this job. You should be wearing gloves if the place is a total disaster, so you don't get cut on anything. Also, if you find that the previous renters were drug addicts, then you should be using a pick-up stick to pick up any drug paraphernalia.
Rent a dumpster
Renting a dumpster, such as from Michael's Rolloff Solutions, is going to be the simplest way for you to get rid of all the junk since most garbage companies have limits on the amount of trash you can throw out at the street for them to pick up. When you have a dumpster, there will only be a small list of items you can't throw away, such as batteries, electronics, tires furniture, etc.
Make a list for repairs
Go through each room and make a note of every little thing that needs to be repaired or replaced. In many cases, knowing you are going to have to replace something will save you from cleaning it, so you aren't wasting time and energy. For example, you may take time to clean a ceiling fan only to find that when you go to turn it on it is broken and needs to be repaired or replaced.
Take care of the repairs
Have all the repairs taken care of first. This way, any dust, dirt, wood shavings or other messiness from the repairs won't fall on the floors you just spent a lot of time cleaning.
Clean the unit
Once you have done all of the above, you will finally be ready to scrub everything and get the unit ready for the next family who will hopefully take better care of the unit.
