Here's and interesting solution to an age old problem.

This tip is from a fellow landlord named Mike.

Soap scum is a problem to get out of tubs and off of shower glass, and sometimes we are forced to buy expensive cleaners, 

NO MORE.

I accidentally discovered several years ago that charcoal lighter fluid melts soapscum, it just wipes off and rinses clean, and you can get a container of the cheap stuff for $1.00  or so, just dont smoke until you rinse it away, it wont harm surfaces either.

Thanks Mike.
