Years ago I was buying a tip sold at Home Depot or Lowes that could flesh a deer cape in just a few minutes! It just ate the gunk right off a cape like a razor! They stopped selling those and I have bought at least a half dozen other types, some of them over $100 and NOTHING works like those old ones! My pressure washers are in the 3800 to 4000 range. Any suggestions on specific name brands or sizes for that range of washer?
