just had my lowers resprayed and there is a shedload of sand in the inside of them where they havent sealed the openings properly or something, anyone got any tips on how to get it out?

tried an air compressor but left a lot in, then some water in the lowers but theres still loads left.

anyone?

cheers, chris.

you could try a jet wash,, but there is the risk of getting the sand trapped even more,,
or find someone with an ultrasonic cleaner

Run a hose inside for a long time. Should eventually clear almost all of the sand.

What about a vacum cleaner, cobble & fudge a thin pipe to the vac hose & a bit of fork manipulation should see it out.

You could always heat them to 1500c but stiffness/strength could be compromised.
