For those that do not know, Groutmaster is a great and safe shower cleaner too. Very safe & profitable also. Here is a testimonial with pics that I got... “I used 2 scoops of (Groutmaster) to 1 gal water, sprayed, let sit 5 mins or so hit real quick with grout brush then rinsed with truck mount. Walls were hit once floor was hit 3 times to remove layers of build up”. By the time the sun came out it was dry and the colors popped like new! https://shop.truckmountforums.com/products/copy-of-groutmaster
