Kärcher 62957570 3-in-1 Wood Plug and Clean Pressure Washer Detergent, 6.295-757.0

Does what it says on the tin; it really really worked on my decking, I had doubts on it because it said safe for plants so assumed weak, but I left it on decking for a couple of minutes then jetted it off and boy the decking was so clean, then I just poured teak oil over the decking and it looked lush. Great value for money too!

I'm happy for purchasing this item. It's a good quality item and it was delivered on time.

Does the job

It’s okay and works well with my Karcher but not sure it actually did anything that the jet wash would not have taken care of.

I have been using this to pre treat a very dirty and unloved deck.The deck has come up a treat, and I do think it helps to loosen the dirt that is to be washed away.When popped into the Karcher Pressure Washer the detergent only gets used when the lance is on low power and so it is very economical in use

Used on 9 year old decking. Pressure washed off heaviest algae first, then applied the cleaner and agitated it using a broom, then jet washed off 15 minutes later and reapplied remainder as per instructions. Cleaned up the decking well.

I am so pleased with the result - easy to apply - rinse - then left to dry and with a little more water and light scrubbing the stains/dirt was removed.

A very useful addition to use with my Karcher K4 jetwash.
