Stylus Cleaning Rituals

"Stylast is supposed to extend stylus life x10."

Given the scale size of the forces operating between stylus and groove and the fact that the groove travels more than half a kilometer past the stylus for just one side, can the above statement be remotely credible?
Stylast is a good product but the claim is snake oil.

Just a swipe with LP#9 between sides.  Never had any problems with  a dislodged stylus or anything migrating up the cantilever. 

After every side, using discwasher stylus brush, and when needed discwasher stylus fluid. The aforementioned products are the original versions. Sometimes I’ll use my vibrating stylus cleaner and fluid for stubborn gunk. Otherwise a few swipes with dry discwasher stylus brush. I always inspect stylus using a 10× Russian made jewelers Loupe.

There are different methods on mounting styluses now. Many still use the old technique of pressing the stylus through a hole in the end of the cantilever. It is harder to hurt this kind of mount. Unfortunately, with many of the modern materials used for cantilevers you can't mount the stylus this way and you have to resort to mounting the stylus in a notch at the end of the cantilever with glue. Any glue can be weakened buy the right solvent. 
For just dust a dry artist brush works great and it is very hard to damage the cantilever with one although I am sure millercarbon will find a way. 
For more stubborn deposits a very weak solution (20%) of isopropyl alcohol is distilled water will work fine. NEVER use denatured alcohol in any concentration as it will melt epoxy. Lyra makes a great stylus cleaning solution (I was given a bottle) but it is silly money.

brush like artist brush.. dirt sometime micro hairs move above the stylus... 

once a while 30 percent alcohol solution if accidently goop up
