Hello and good afternoon all, I hope everyone’s been out making the most of this weather.
Just a quick one to ask if people who have had experience cleaning bolt holes would recommend any brushes in particular.
I started using some old toothbrushes/boulder brushes, which worked pretty well but were slow and not very durable.
Then I moved onto a tea pot spout brush which was pretty effective but again not really designed for limestone in mind and so again not very durable.
Apparently some climbing gear manufacturers make a specific brush but it’s pretty pricey for what it is, has anyone got any better value but as effective suggestions or suggestions on how to compromise?
Oh and the bolt holes are 10-12mm.
Thanks in advance, Emilio.
