waltin,
It is according to how strong it is. It may have to be diluted a good bit to use, or maybe not. The percentage of acetic acid is in Vinegar is around 8%, but you would need it down to that percentage range. Its pretty mild, as the amount of Chlorine in bleach isn't that strong. A too strong amount of any acid could damage wood fibers when applied, and what you have, I couldn't say. See the two links below;

This is from the article on Bleach from Wikipedia:
"Chlorine-based bleaches"
"Chlorine-based bleaches are found in many household cleaners. The concentration of chlorine-based bleaches is often expressed as percent active chlorine where one gram of a 100% active chlorine bleach has the same bleaching power as one gram of chlorine. These bleaches can react with other common household chemicals like vinegar and ammonia to produce toxic gases. Labels on sodium hypochlorite bleach warn about these interactions".
And,
"Sodium hypochlorite"
Main article: Sodium hypochlorite
"Sodium hypochlorite is the most commonly encountered bleaching agent, usually as a dilute (3-6%) solution in water. This solution of sodium hypochlorite, commonly referred to as simply "bleach", was also one of the first mass-produced bleaches. It is produced by passing chlorine gas through a dilute sodium hydroxide solution"
