I have a cheap bong with a 6 arm percolator. The resin makes the bong taste and look bad. Ive had this bong for 8 months and have cleaned it with 420 cleaner, grunge off, iso and salt and gasoline which worked the best but the perc is stain really bad with resin even tho i empty water after every session. I scrub it with a baby bottle scrubber which gets my other clear bong spotless but I don't want to break the percolator. Any tips would be appreciated.
