I’ve both there. Just never used them properly
Bought a proper lance last week so intend on at least attempting some safe washing over winter so the car doesn’t look like eff all by the time spring comes round.
if the car is caked in muck i usually spray articulate on then let it dwell. if its bad, i put foam on top
for a quick rinse mid week i would spray on articulate and power hose off - might take two passes with articulate but usually leaves the car clean - having the ceramic coating on the golf will make it a lot easier
