It's really not a minimal extra cost. PBW is $20 for 4 lbs ($5/lb), Oxiclean is $6.50 for 2.5 lbs ($2.60/lb) or $11 for 96 oz. ($1.83/lb) and apparently "Sun Oxygen Cleaner" is the same as Oxiclean and is available for $1/lb.
I'm not trying to convince you to use oxiclean, or anything else, but PBW is way more expensive.

LLC is a 38% solution of sodium hydroxide.
PBW is not caustic. I didn't say it was. I was simply pointing out that you can buy ACTUAL
caustic at your LHBS.
