Anti-mould stick - where can I find it?

Question:Hello,
A while ago I saw an ad in a daily newspaper for an anti-mould stick. You could simply apply it on your bathroom sealant, and it would prevent mould for a number of years. Now, I can not remember what it was called or where to get it. Any help?

I am looking for this stick - NOT for sprays/bleach/sealant etc.
Many thanks!

I truly have no real clue, sorry, but suspect any home improvement store might help.

MOLD can be easily maintained/prevented, by regular cleaning, and it seems that should be a prime directive for a bathroom anyway. Clorox Clean Up is a great product, used regularly, and not as damaging as straight bleach.

"Apply onto bathroom Sealant"? Sealed grout, or rather the intent of a grout sealer is to aid in keeping grout clean and SEALING aids in making anything that attacks grout, easier to clean.

With all due respect; products are HYPED so often beyond their capabilities or effectiveness.
