Most LFS's will carry the razor cleaner tools....I see them at my favorite LFS in Lubbock all the time. Long green handle...comes with razor....under $5.00...not a bad deal at all.
I seldom use the razor myself...only when the coraline has accumulated to the point that the magnet and/or credit card can't remove it all easily. Most of the time daily use of the magnet and weekly cleaning with a old credit card.:thinking:
