The time it takes to clean a greasy and messy one-bedroom apartment can vary depending on several factors, including the extent of the mess, the size of the apartment, the level of cleanliness desired, and the individual's cleaning speed and efficiency. However, I can provide you with a general estimate.
For a moderately messy one-bedroom apartment, it may take anywhere from 2 to 4 hours to clean thoroughly. This estimate includes tasks such as decluttering, dusting, vacuuming or sweeping, mopping floors, cleaning surfaces, scrubbing greasy areas, cleaning the kitchen appliances, sanitizing the bathroom, and taking out the trash.
If the apartment is exceptionally greasy or heavily soiled, it might require additional time and effort. In such cases, it could take 4 to 6 hours or longer to clean the apartment thoroughly.
It's important to note that these are rough estimates, and the actual time required can vary based on the factors mentioned earlier. Additionally, having a systematic approach, using the right cleaning products and tools, and working efficiently can help reduce the overall cleaning time.
