Here is a house in Bukit Timah that we recently had the pleasure of working with. The house was so cluttered and messy that we were not even able to open the front door! It resembled a dump yard. In their bedroom, the clothes were piled up to chest height.
This is what we did.
1) We took some kerosene
2) We lit the clothes on fire
3) We cleaned up the ashes
This is what the place looked like after we were done
