Best thing to do often is to disassemble yourself - give to them in parts all in a tray, all in separate bags and all labelled up for each cylinder and valve.
They'll then clean it for you and re-assemble - then you know it went back together right.
If you do decide to remove valves yourself - don't bother with getting a spring compressor - remove bucket, get a socket and a strong magnet - place magnet up end of socket and secure with glue or similar - place socket over valve retainer and twat with hammer. Collets fly off, stick to magnet - bam easy.
