Wet & Forget promo code - November 2026

Black Friday pricing has landed and the headline cuts are reaching the 50% mark on selected outdoor cleaning lines. This is the time of year where the 5L concentrate bottles and combo roof-and-deck kits get their steepest markdowns. Stock tends to thin out quickly on the larger sizes during this window, so if you've been holding off on a full-property clean-up, this is the moment to move

A cashback offer is currently active that returns 20% of your order value as credit toward a future purchase. It's not an upfront discount - you pay full price at checkout and the credit lands in your account afterwards. This one suits repeat buyers who know they'll need another round of cleaner in a few months, since the credit only has value if you come back to spend it

The deepest discount currently floating around is 35% off, and it's tied to bundle purchases rather than single bottles. Pairing the outdoor concentrate with a dedicated sprayer or the roof cleaning kit is what unlocks this rate - individual items won't trigger it. Worth checking whether the bundle already includes a discounted sale item, since that's where the compounding savings get serious

Tradies, property managers, and anyone buying in volume can tap into the trade pricing tier this month. The discount applies to bulk concentrate sizes and multi-packs - the sort of thing you'd want for doing a full roof or deck restoration rather than a small spot clean. You'll need to hit the trade qualifying spend, but the per-unit price drops considerably once you're through that gate

Right now there's a sitewide deal knocking 20% off when your cart hits NZD60 or more. That's a solid chunk off outdoor cleaners, sprayers, and roof treatments - enough to stock up on the larger concentrate bottles where the per-litre value is already strong. Threshold includes sale-priced items, so stacking this on top of marked-down stock is where the real savings sit
