See more Review: Effective and Convenient Toilet Maintenance - I prefer cleaning products that work consistently between deep cleans. This cistern block helps keep the toilet clean, fresh, and hygienic. Pros: β€’ Long-lasting and gradually used β€’ Water turns dark blue, making it easy to tell when it’s depleted β€’ Keeps the toilet looking clean between scrubs β€’ Pleasant but not overpowering smell β€’ Affordable and great value for the price β€’ Can be paired with other cleaning products Cons: β€’ Fragrance is subtle, which might not be enough for those looking for a stronger scent β€’ Last for approximately 4-5 days Review: great at hiding skids - Smells OK, last longer than the small size, and as expected leaves a pleasant blue colour in the bowl. The key strength of these though is their ability to hide even the meatiest of peanut butter highway marks. They also seem to help the water release particularly stubborn, stuck-on clangers, most often found after a day of high meat intake, such as a summer BBQ. Too early to tell if they will help with the hard water marks (but these are often impossible to see anyway due to the layer "mud" left behind the morning after a great chicken jalfrezi from Akbar's) ## Features - Causes serious eye damage. - Causes skin irritation. - Harmful to aquatic life with long lasting effects. - May cause an allergic skin reaction. - Foams for up to 8 weeks - Blue water - Safe to use with septic tanks and all other toilet cleaners - Store spare blocks in their pack in a cool, dry place ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00G9Y0T2U | | ASIN | B00G9Y0T2U | | Best Sellers Rank | 28,848 in Grocery ( See Top 100 in Grocery ) 300 in Toilet Cleaners | | Brand | Bloo | | Country of origin | United Kingdom | | Customer Reviews | 4.3 4.3 out of 5 stars (773) | | Customer reviews | 4.3 4.3 out of 5 stars (773) | | Date First Available | 12 Nov. 2015 | | Format | Foam | | Is discontinued by manufacturer | No | | Item model number | 100445613 | | Manufacturer | Jeyes Limited | | Manufacturer contact | Jeyes Ltd, Brunel Way, Thetford, Norfolk, England, IP24 1HF. | | Product Dimensions | 2.2 x 10.5 x 15 cm; 70 g | | Storage Instructions | Store in a cool dry place. | | Units | 70.0 Grams | | Weight | 50 g | ## Product Details - **Brand:** Bloo - **Item form:** Foam - **Item weight:** 70 Grams - **Material feature:** Long lasting - **Number of items:** 1 - **Scent:** Fresh - **Special feature:** Concentrated, Prevents Limescale - **Specific uses for product:** Toilet - **Surface recommendation:** Toilet - **Unit count:** 70.0 Grams ## Images ![Max In Cistern Original, 70g - Image 1](https://m.media-amazon.com/images/I/717IUJIjH5L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Effective and Convenient Toilet Maintenance *by C***T on 16 November 2024* I prefer cleaning products that work consistently between deep cleans.
