The brown patch can also be seen on 1032J...
Many of the KJ buses have problems in cleaniness...
1157H is more like SP sided over to 67...
But over the day, and particularly for A/P buses, more litter and
dirt forms up...
To a lesser extent, the S buses, while at depot, collects dust and
'kah zhua' from open doors and window(s). Thats why S and SP buses
dun really escape from the wrath of dirt and little/large
insects...
