|Disagreed, use base cleaner, yeah they may dry out hte base but wax replenishes it anyways. I have been using base cleaner my whole life over 20 years of skiing and tuneing and my skis are always faster than my bro in laws. He uses his method I use mine. Don't get me wrong here either, I do not use cleaner every single time I wax. When it is needed only. Experience will let you know when that time comes.
See that is the great thing about America, everyone is entitled to their own opinion.
Please tell me who here is at the world cup level and is going to notice a difference. I am willing to bet Noone here is!
When is it needed? And how can you damage your ski hot-scraping them (you said that before)?
Seriously, base cleaners have their place unless you're racing, but once you start worrying about having a fast ski for the day, they become a non-option as they eliminate all the waxing that has been done to the ski beforehand. Sometimes, this can be good (the snow is at -20F and all the base layers are very soft wax), but most of the time it'll be detrimental, both in time spent (imagine having to saturate the ski over again!) and ski performance.
Also, hot-scraping, in racing, does not only serve as a way to clean the ski, but to also remove strcture fuzz and small base irregularities : the more you hot scrape, the smoother the base, the faster you'll be, period.
Also, this guy does advise to hot-scrape in order to clean base and he DOES work on the WC.http://www.racestocksports.com/Text/...aintenance.pdf
