One thing I must mention is that you should never mix it with hot water. This is clearly written on the bottle by the manufacturer. If you mix it with hot water, it turns into wax and this wax can melt and damage your pipes.

It is however slow in its operations and may take some time to actually clear away the pipes that have been clogged, but it will do this very well, so the delay is well worth it.

Bottom line: This is one of those products with very positive customer feedback. If you have sinks that keep clogging, I highly recommend this product as it will not disappoint. Everyone who used it had lots of positive things to share about it.
