Starbrite Instant Fresh Toilet Treatment 946ml Lemon Grove is the sort of gear you throw in the locker and forget about until the tank hits around 80 litres and needs a dose. At 29.6ml per 18.9L it is easy to measure out with a basic cup and the 946ml bottle covers up to 1211L of tank capacity, so one container will get you through a solid run of weekends.

The biodegradable formula comes in a tough 946ml bottle that handles being knocked about in a hatch or caravan cupboard. The same chemistry is used across the 473ml, 946ml and 3.79L range, all locked to that 29.6ml per 18.9L ratio, so you do not have to relearn the mix if you upsize tanks. The lemon grove scent is made for tight cabins and vans where every bit of odour control counts.

Q: How many standard treatments can I get from one 946ml bottle?

You can get roughly 32 standard treatments from one 946ml bottle. Each treatment uses 29.6ml of liquid per 18.9L of tank capacity. If your tank holds around 75L you will use about 120ml per dose. That works out to several full tank treatments before you need to replace the bottle.

Q: Can this toilet treatment be used in cassette-style portable toilets?

Yes, it can be used in cassette-style portable toilets that accept liquid chemicals. The key is to size the dose to the cassette capacity using 29.6ml per 18.9L. Most cassettes are well under 100L, so only a small amount is needed. Always add the treatment to the waste tank side, not the flush water tank.

Q: Does the lemon grove scent overpower small cabins or caravans?

No, the lemon grove scent is mild and intended for confined spaces. It works to mask and reduce odours venting from holding tanks rather than flooding the cabin with perfume. With the correct 29.6ml per 18.9L dose you get odour control without a heavy fragrance. Overdosing can increase scent strength without extra benefit.

Q: How should I store the 946ml bottle between trips?

Store the bottle upright in a cool, dry spot out of direct sun. The screw cap should be closed firmly after each use to prevent spills in lockers. Keeping it away from food storage areas is good practice due to its chemical nature. A small plastic tub or tray can catch drips if the bottle is packed with other gear.
