Make mine myself and put in old Spray bottle. I've got through some cheapo gloves though. Strong ones are needed and yes, it needs to be locked away like other cleaning stuff. Normal stuff makes my eyes sting though but I still use that too for other jobs.
Find Borax very good for general cleaning and have got my bare hands in this before...is that corrosive/alkaline too Katy and Whizzz?
Think a bit of elbow grease is really honestly all you need most of the time TBH!
