It will remove these stains no problem. The longer you leave them, the harder it will be to remove however. Basically it is a chlorine based cleaner so if you feel like using str8 chlorine go for it. DO NO USE HYDRO-CHLORIC ACID. Re: Timber stains on concrete...HELP! 12Nov 21, 2015 9:41 am I read that bleach works, so I went and grabbed the bottle from my cupboard and starting working. It was amazing how well it worked. The stains just disappeared at a touch or the sponge. Then my husband said he was smelling fish and chips, and looked at my container. It was plain old VINEGAR! But, believe it or not, It really works. Maybe I should do ad for @Spec savers. Re: Timber stains on concrete...HELP! 13Jun 13, 2018 8:21 am Tanin stains are Best removed with oxalyc acid. This is what timber coating products use as a prewash to remove the tannins as a base agent. It used to be called “oxalyc acid” by diggers in Bunnings. It’s now called “rust and stain remover”. Still made by diggers. It comes in a powder/granular form which you mix with water. Wet down surface to clean. Apply mix (use bucket and brush). Leave for 10 mins then thoroughly rinse with water. Repeat if necessary. ive been doing this successfully for 20 years.

A few days later...it pretty much rained from 8am to 7pm. Now I have timber stains all over the concrete. How can I/what can I do or use to get rid of these stains? If I don't, the missus will probably kill me considering the concrete is barely 3 months old. Thanks in advance. Hey mate, Did you manage to get the stains out?? I’ve got the same issue, have tried Oxcylic acid but it’s still there Clarendon Denton 24 | Gold Coast Status: Internal fitout!

It's called T Rex and will stick your timber to the concrete. Cheers Simeon 1 1551 |
