Teak garden furniture is strong and durable, but mould can develop in damp or shady weather. With a simple method your furniture will quickly look fresh and clean again, and you can prevent new growth. Looking to expand or replace your set afterwards?

Step 1: Thorough cleaning for mould

Method
- Mix vinegar and warm water in a bucket.
- Fully dissolve the oxygen bleach powder.

- Wet the furniture and brush the mixture in with the grain.
- Let it sit for 10-15 minutes, keeping the wood damp.
