Plenty of rain over here (UK) to get you rope clean, dismantling an ash with a dogs leg over a stagnant pond, had a section of rope trail in the water (my fault not the groundies) therefore really began to smell and for the sake of a quick wash i'd rather do that then have a pile of stagnant water run into my lap, or down the arm is one of the worst!!
Tree was also located on a muddy bank and try as you might to keep the line in the rope bag is just wasn't happening, so rather than leave the grit and dirt in the line thought i'd wash it, washed and dry ready for next day.
Pre use inspection of kit is important to me and want to be able to see what is going on beneath the grim, also believe in the fact that many climbers set an example to those who work within your team, when you try and teach the guys about respect for kit (especially when it's yours and your bills) how can you expect them to conform if you can't set the example.
Do as i say, not as i do !
